Harnessing beneficial bacteria to remediate antibiotic-polluted agricultural soils: integrating source diversity, bioavailability modulators, and ecological impacts

  • Unit for Environmental Sciences and Management, North-West University, Potchefstroom, South Africa

Abstract

Antibiotic contamination in agricultural soils, primarily from manure application and wastewater irrigation, has emerged as a critical threat to food security, environmental health, and public safety due to the proliferation and persistence of antibiotic-resistant genes. This review examines the diverse sources and ecological impacts of antibiotics in soil, including their alteration of microbial community structures, promotion of horizontal gene transfer, and subsequent risks to plant and human health. It further evaluates how soil properties, such as pH, organic matter content, and texture, influence the bioavailability of antibiotics and modulate their degradation dynamics. Emphasis is placed on the bioremediation potential of beneficial bacteria, detailing key mechanisms such as enzymatic biodegradation, biosorption, biofilm formation, and the formation of synergistic microbial consortia capable of utilizing antibiotics as nutrient sources. In addition, the manuscript critically discusses the regulatory, technological, and scalability challenges inherent to deploying microbial bioremediation strategies, including integrating gene editing and systems biology approaches under a One Health framework. By synthesizing molecular insights with environmental and policy considerations, this review provides a comprehensive assessment of current bioremediation strategies and outlines future directions to mitigate the ecological and health risks associated with antibiotic pollution in agricultural ecosystems.

Introduction

The discovery of penicillin marked the beginning of modern medicine (Hutchings et al., 2019), which has led to antibiotics being used as a basic method of treating diseases in people and animals for decades (Xie et al., 2018). The expansion of large-scale animal production systems has raised the demand for veterinary antibiotics, which are used not only to treat infections but also to prevent disease and promote growth. Many veterinary antibiotics are supplied in animal feed at subtherapeutic levels to promote growth (Gonzalez Ronquillo and Angeles Hernandez, 2017; Caneschi et al., 2023). However, many antibiotics are excreted intact or as active metabolites because they are not entirely absorbed (Tiedje et al., 2023). Antibiotic use in farm animals creates an environment that promotes the formation of antibiotic-resistant bacteria (ARBs), which spread through manure and the surrounding ecosystem.

Agricultural soil is crucial to preserving food security and ecological balance. It is a critical resource for crop production, influencing crop yield, quality, and environmental health. The United Nations Sustainable Development Goals (SDGs) emphasize the need for sustainable agricultural practices in ensuring food security, especially considering the world’s growing population and the increasing constraints of climate change. Among the many challenges confronting agricultural systems, antibiotic contamination poses a significant threat to soil health and food safety, raising concerns about the emergence of antibiotic-resistance genes (ARGs) in agricultural ecosystems. The SDGs, particularly goal 2, seek to eliminate hunger, ensure food security, and promote sustainable agriculture by 2030. This goal acknowledges that sustainable agriculture is critical to ensuring food security and promoting nutrition. However, the presence of antibiotics in agricultural soils, commonly caused by manure application and the use of wastewater for irrigation, affects this goal. The widespread use of antibiotics in livestock farming has resulted in the accumulation of these substances in the environment, which can harm soil microbiota and disrupt essential soil functions like nutrient cycling and organic matter decomposition (Udikovic-Kolic et al., 2014; Christou et al., 2017; Checcucci et al., 2020). Beneficial microbes that have developed resistance can spread through the food chain to humans through the consumption of affected crops (Pepper et al., 2018; Lima et al., 2020; Fatoba et al., 2021). Studies have demonstrated manure to be a hotspot for spreading ARGs, promoting horizontal gene transfer among soil bacteria (Deng et al., 2024; Wang S. et al., 2024). Antibiotics in soil alter microbial community structure and functional capabilities, potentially reducing soil fertility and increasing vulnerability to pests and diseases (Yang et al., 2016; Cycon et al., 2019). The persistence of these antibiotics in the soil is affected by environmental factors such as soil type, pH, and organic matter content, thereby affecting their bioavailability and degradation (Li et al., 2022; Liu et al., 2022b; Cui et al., 2023). Antibiotic resistance spreading through the food chain is a major public health concern, as infections caused by resistant bacteria are often more challenging to treat, resulting in increased morbidity and mortality (Han et al., 2022; Elder et al., 2023). Hence, there is a critical need for integrated methods to address antibiotic usage in agriculture, promote sustainable farming techniques, and protect soil health to secure food for future generations.

One of the sustainable solutions to combat this issue is the use of beneficial microbes. Beneficial microbes offer an environmentally friendly and sustainable solution for detoxifying antibiotics in agricultural soil. The effect of the increased concentrations of these antibiotics on soil microbial abundance, diversity, and communities, as well as microbial functions and processes in the soil, can be ameliorated by microbial bioremediation. In relation to antibiotic stress, beneficial microbes have been reported to improve soil health and alleviate plant stress through various mechanisms, such as siderophore production, biotransformation, biosorption, and biodegradation. Many soil contaminants, including antibiotics, pesticides, heavy metals, oil spillage, etc., have been biodegraded using beneficial microbes. For instance, the bacterium Cupriavidus metallidurans strain MSR33 has demonstrated significant potential in remediating mercury-contaminated soils, showing the ability to tolerate heavy metals and positively influence the nitrogen cycle in the soil ecosystem (Bravo et al., 2020). In another study by Xu J. et al. (2021), engineered strains were developed to enhance the degradation of p-nitrophenol through specific enzymatic pathways, which are crucial for breaking down complex organic molecules. Therefore, beneficial bacteria can be used to mitigate the effects of these contaminants. In addition to their bioremediation properties, they help improve soil and plant health, promoting plant growth and improving food security (Olanrewaju et al., 2017, 2024a).

Since the increased accumulation of antibiotics on agricultural soil is fast becoming a cause for serious concern because of their detrimental effect on soil microbiome and their role in increasing antibiotic resistance, it is of paramount interest to find a way to alleviate these impacts using an eco-friendly and sustainable approach. Keeping this in mind, this review attempts to present an environmentally sustainable approach to mitigating the effects of these antibiotics on agricultural soil, soil microbial community, and, ultimately, plant health.

Sources and ecological impacts of antibiotics on agricultural soil

Sources of antibiotics in soil

Anthropogenic activities are the primary sources of antibiotics in the soil. Human activities have been the primary cause of major disasters such as climate change, flooding, loss of agricultural soil, etc., affecting the environment. Antibiotics are meant to address various medical concerns in humans and animals. However, some antibiotics find their way into agricultural soils in their active forms, which is a serious cause for concern. We look at the sources of antibiotics in agricultural soil. Antibiotics in agricultural settings have complex and significant ecological effects across several environmental compartments, including soil and water (Table 1). Antibiotics used extensively in crop and animal production have generated questions about their environmental persistence and possible disturbance of the ecological equilibrium.

(2021), and Qian et al. (2022)

Sources of antibiotics in agricultural farms.

The sources of antibiotics in the agricultural field are multifaceted and involve various practices that contribute to the presence of these compounds in the environment (Table 1). Antibiotics in agriculture primarily stem from their application in crop management through direct application, manure application (Muhammad et al., 2020; Khmaissa et al., 2024), and wastewater irrigation (Li T. et al., 2024; Phan et al., 2024), which raises significant concerns regarding antibiotic resistance and environmental health.

One of the primary sources of antibiotics in agriculture is the use of these compounds in livestock. Antibiotics are administered to animals for therapeutic purposes, growth promotion, and disease prevention. Reports indicate that agricultural antibiotic use accounts for a substantial portion of total antibiotic production, with estimates suggesting that it may represent up to half of all antibiotics produced in the United States (Looft et al., 2012). This extensive use creates a reservoir of ARB and ARGs in animal waste, potentially contaminating soil and water systems (Williams-Nguyen et al., 2016; Zhao et al., 2023). Manure application from livestock operations to fields is a direct pathway for introducing these antibiotics and their associated resistance traits into agricultural ecosystems (Udikovic-Kolic et al., 2014; He et al., 2020).

In addition to livestock, the use of antibiotics in crop production is another significant source. Some antibiotics, such as oxytetracycline and streptomycin, are applied to control bacterial diseases in plants, the uptake of these antibiotics by crops can lead to their accumulation in edible plant tissues, raising concerns about food safety and potential health risks to consumers (Yin et al., 2023).

Furthermore, applying treated wastewater for irrigation, which often contains residual antibiotics, introduces additional sources of these compounds into agricultural soils (Sorinolu et al., 2021) (Table 1). The presence of antibiotics in irrigation water can stem from municipal wastewater treatment plants that discharge effluents containing various pharmaceuticals, including antibiotics, into water bodies used for agricultural purposes (Khan et al., 2020; Gworek et al., 2021).

In addition to direct application, manure application, and wastewater irrigation as major sources of antibiotics in agricultural farms, other not-so-common/reported sources include biosolids, sludge, compost, and pharmaceutical waste application (Table 1).

Ecological impacts of antibiotics on agricultural soil

The environmental persistence of antibiotics is a critical factor that exacerbates their impact. Studies have shown that antibiotics can remain in agricultural soils for extended periods, mainly when introduced through manure or sludge (Ghirardini et al., 2020; Buta et al., 2021) (Figure 1). This persistence facilitates the continuous selection of antibiotic-resistant bacteria and contributes to the spread of ARGs within the soil microbiome (Kaviani Rad et al., 2022). The interaction between antibiotics and soil contaminants, such as heavy metals and organic fertilizers, further complicates the dynamics of antibiotic resistance in agricultural settings (Topp et al., 2018). Moreover, the role of agricultural practices in disseminating antibiotic resistance cannot be overstated. The misuse and overconsumption of antibiotics in agriculture have exerted selective pressures on microbial communities, driving the evolution of resistance (Sanderson et al., 2018). The presence of high levels of antibiotic resistance in both urban and rural soils highlights the widespread nature of this issue, indicating that agricultural practices significantly contribute to environmental resistance (Osbiston et al., 2021). The connection between antibiotic use in agriculture and the emergence of resistant strains of bacteria directly threatens public health, as these pathogens can be transmitted to humans through the food chain (Iwu et al., 2020; Samreen et al., 2021) (Figure 1). The implications of antibiotic use in agriculture extend beyond the immediate agricultural environment. ARGs are transmitted from agricultural settings to human populations through various pathways, including consuming contaminated food products, direct animal contact, and environmental exposure. The interconnectedness of agricultural practices and human health underscores the need for comprehensive strategies to mitigate the risks associated with antibiotic resistance. This includes implementing better antibiotic stewardship practices, reducing unnecessary antibiotic use in livestock, and enhancing the monitoring of antibiotic residues in agricultural products (Topp et al., 2018).

Figure 1

The occurrence of antibiotics in soil and water systems has been reported in various studies (Bilal et al., 2020; Kovalakova et al., 2020; Lyu et al., 2020; Snow et al., 2020; Jia et al., 2023), with studies indicating that these compounds can persist and accumulate, posing risks to non-target organisms and disrupting essential ecological processes (Du and Liu, 2012; Danner et al., 2019) (Table 2). For instance, it is reported that the limited understanding of the ecotoxicological relevance of antibiotics, particularly in agricultural organic fertilizers and plant-based products, can lead to unintended exposure to various organisms (Du and Liu, 2012). Introducing antibiotics into the environment can significantly impact microbial communities, which are critical in nutrient cycling and decomposition of organic matter. In their study, Danner et al. (2019), emphasized that non-target organisms, integral to ecological processes, are inevitably exposed to antibiotics when these substances enter surface waters. This exposure can lead to shifts in microbial community structure, resulting in decreased biodiversity and altered ecosystem functions. The disruption of microbial communities can hinder nutrient cycling processes, such as nitrification and denitrification, which are vital for maintaining soil fertility and water quality (Ding and He, 2010; Cycon et al., 2019). In addition, the presence of antibiotics in agricultural settings has been linked to the emergence and proliferation of ARB and ARGs. The use of antibiotics in livestock farming creates selective pressure that fosters the development of resistance among microbial populations. The environmental pollution caused by antibiotic residues is particularly concerning, as it can spread resistant strains into the food chain and water supply, posing a significant public health risk (Kraemer et al., 2019; Wu et al., 2022). The impact of antibiotic pollution extends beyond microbial communities to include aquatic and terrestrial organisms. Studies have shown that exposure to sub-lethal concentrations of antibiotics can induce physiological and behavioral changes in various species. Such findings underscore the need for comprehensive assessments of the ecological risks associated with antibiotic use in agriculture. In addition to direct effects on organisms, antibiotics can interact with other environmental pollutants, leading to synergistic or antagonistic effects that complicate risk assessments. The study by Kraemer et al. (2019) highlights the potential for antibiotic pollution to influence human health through environmental pathways, emphasizing the importance of understanding the interactions between antibiotics and other contaminants. The cumulative effects of multiple antibiotics in the environment can lead to increased toxicity, further exacerbating the ecological impacts.

Effects of antibiotics on soil microflora.

Effect of antibiotics on ARGs, ARBs, soil microbiome, and plant health

When animal-administered antibiotics find their way into the soil through manure application, they place greater pressure on ARG selection because of their prolonged stay in the soil. Although they are in small doses, the impact of the duration of exposure on ARG and the microbiome is more adverse than their impact on animals because the duration of exposure in animals is short. Studies have been conducted to show the effects of antibiotic exposure to ARGs in soil, for example, a study by Zhu et al. (2013), investigates the prevalence of ARGs in soils associated with large-scale Chinese swine farms. Using a high-throughput quantitative PCR, the study reported 149 unique ARGs, many significantly enriched compared to control soils, with fold increases reaching as high as 28,000. Similarly, studies have shown that using antibiotics in livestock creates selective pressures that favor the proliferation of resistant bacteria, leading to increased ARG abundance in fecal matter (Storteboom et al., 2010). The continuous application of antibiotics in agriculture selects resistant strains and facilitates horizontal gene transfer among microbial communities, amplifying the spread of resistance traits (Gromala et al., 2021; Larsson and Flach, 2022).

Manure is often nutrient-rich and serves as a reservoir for various antibiotics, which can significantly influence the soil microbiome. Studies have shown that introducing manure into soil can increase the abundance of ARGs, as these genes can be transferred among microbial populations through horizontal gene transfer mechanisms. For instance, the study by Zhu et al. (2019) demonstrated that the trophic transfer of ARGs occurs within soil detritus food chains, indicating that organisms feeding on manure can acquire these resistance genes, amplifying their presence in the soil microbiome. Furthermore, Negreanu et al. (2012) noted that while the application of manure with high levels of ARBs initially increases resistance in the soil microbiome, this resistance often returns to baseline levels within six months, suggesting a dynamic equilibrium influenced by environmental factors and microbial interactions. The persistence and spread of ARGs in soil are influenced by various factors, including the type of manure applied and the microbial community structure. Hilaire et al. (2022) found that subsurface manure injection can reduce the surface transport of ARGs but may create localized hotspots of resistance within the soil. This phenomenon underscores the complexity of manure application practices and their varying impacts on soil health. Additionally, Xu H. et al. (2021) highlighted the role of soil bacteria as carriers for plasmids that harbor ARGs, facilitating their transmission to plant endophytic bacteria, which can further propagate resistance within plant microbiomes. This interaction between soil and plant microbiomes is crucial, as it can lead to the establishment of resistant strains in crops, posing potential risks to food safety and human health.

The soil microbiome itself is significantly affected by manure application, which can alter microbial diversity and community composition. Banerjee and Heijden emphasized that urban soil microbiomes often contain higher levels of ARGs and genes associated with human pathogens, likely due to anthropogenic influences such as manure application (Banerjee and van der Heijden, 2023). The introduction of manure can enhance microbial diversity, as reported in the study by Sun et al. (2021), which reported that manure application introduced specific resistance genes to surface soils, thereby reshaping the microbial landscape. This alteration in microbial communities can have cascading effects on soil health, nutrient cycling, and plant interactions, ultimately influencing agricultural productivity. The impact of manure-derived ARGs on plant health is a critical area of concern. Research indicates that ARBs in the soil can affect plant growth and health, potentially leading to reduced crop yields. Muurinen et al. (2017) reported that while manure application does not permanently alter the resistance profile of soils, the cyclic changes in the resistome can affect plant health over time. Similarly, Jauregi et al. (2021) also reported that the mobility of antibiotic resistance from manure to soil and vegetable microbiomes is a significant risk factor, as it can lead to the contamination of food crops with resistant pathogens. This highlights the need for careful management of manure application to mitigate risks associated with antibiotic resistance in agricultural systems. Environmental factors and management practices further complicate the dynamics of ARGs and ARBs in manure-amended soils. For example, Wang E. et al. (2024) noted that long-term manure application can change bacterial communities in the rhizosphere, which may influence plants’ uptake of contaminants such as heavy metals and pathogens. This interaction between soil microbiomes and plant health is critical, as it can determine the overall resilience of agricultural systems to stressors such as disease and nutrient deficiencies. Additionally, heavy metals in manure can exacerbate the risks associated with antibiotic resistance, as these metals can co-select for resistant strains.

Besides manure application, antibiotics can be introduced into agricultural soil through irrigation. About 70% of freshwater globally is being used for irrigation, meaning that water demand will increase in the near future (Sharma et al., 2020). This has made wastewater irrigation a valuable resource for water shortage, especially in developing countries, and this may be more common in the near future (Tian et al., 2021). Although wastewater irrigation offers positive advantages as it contains nutrients important for soil fertility and plant health, it also contains pollutants (Kodesova et al., 2024), including heavy metals (Ahmed et al., 2023; Ugulu et al., 2024) and antibiotics (Mehanni et al., 2023; Mohy et al., 2023), which are environmental risks. Antibiotics in wastewater can increase the dominance of ARBs through selective pressures and horizontal gene transfers (Guo et al., 2017). Therefore, this poses a health risk to humans as these strains can be acquired through the food chain. As a matter of concern, reported exposure to ARBs through the food chain from agricultural soils irrigated (Rahman et al., 2021; Geng et al., 2022).

Potential risks of antibiotics in agricultural soil to food security and human health

The soil consists of diverse microbial communities, and bacteria have been reported to be the most abundant (Olanrewaju et al., 2017). Bacteria carrying ARGs are also present in the soil. However, the introduction of antibiotics through manure application and wastewater irrigation systems, albeit in small concentrations, for a prolonged period, exerts selective pressure on the soil microbiome (Banerjee and van der Heijden, 2023). In response, as a survival mechanism, the soil microbial community develops resistance to these antibiotics to protect itself. This increases the presence of ARBs and ARGs in the soil microbiome. In addition, the manure and wastewater can carry ARBs and ARGs, which are directly transferred to agricultural soil (Mohy et al., 2023; Zhang Y. et al., 2023). Hence, although beneficial to plant growth, these activities are key to disseminating ARBs and ARGs in agricultural soil. However, studies of the potential spread of antibiotic resistance in the environment have mostly focused on the evolution of antibiotic resistomes in soil and wastewater, with little attention paid to the subsequent spread of antibiotic resistance via plant microbiomes. Many studies have investigated the potential dissemination of antibiotic resistance in the environment (including agricultural soil and wastewater) using qPCR, genomics, metatranscriptomics, and metagenomics (D'angelo, 2023; Ferreira et al., 2023; Kim et al., 2023; de Farias et al., 2024; Molale-Tom et al., 2024; Olanrewaju et al., 2024b,c). This indicates the urgent need for proper waste disposal and recycling for sustainable agriculture (Chen et al., 2019).

Soil microbiomes enter the plant endosphere through the root surface. The plant consists of the endosphere and the ectosphere. The endosphere is inside the plant tissues, while the ectosphere is further categorized into the plastisphere (leaf surface), the capisphere (fruit surface), and the rhizosphere (root surface). The most affected plant compartments in the agricultural fields are the rhizosphere, plastisphere, and capisphere, depending on irrigation and manure application. The microbiome in soil finds its way to the rhizosphere, and when the microbiome is abundant in ARBs, these also make their way to the rhizosphere. Likewise, ARBs in irrigation wastewater are attached to the plastisphere and capisphere, the plant’s above-ground parts. Irrigation affects above-ground and below-ground plant compartments, while manure application affects the below-ground part because it is applied directly to the soil. The entry of the microbial community from the ectosphere into the endosphere provides a transfer route for ARBs and ARGs from manure and wastewater to the soil and the plants (Scaccia et al., 2021). This has been reported in many studies, for example, according to the study by Xu H. et al. (2021), soil bacteria can transfer plasmids harboring ARGs to plant endophytic bacteria, especially those belonging to the phylum Proteobacteria, which contains a variety of plant and human pathogens. This transfer risks human health and agricultural output by making these pathogens more antibiotic-resistant and virulent. These transfers have significant ramifications, indicating that soil management techniques may unintentionally contribute to the spread of antibiotic resistance in agricultural systems. In addition, the composition of the soil microbiome plays a crucial role in determining the health of plants (Banerjee and van der Heijden, 2023). The initial soil microbiome was reported on plant health (Wei et al., 2019), with shifts in microbial communities occurring due to root exudates that alter the microbial landscape. Therefore, the soil microbiome’s initial state can influence the types of bacteria that colonize the plant endosphere, including those that may carry ARGs.

Upon entering plants, these ARBs and ARGs can further find their way into humans through consumption. Although the direct transfer of ARBs and ARGs from plants to humans has not been fully substantiated, this possibility is very high, especially in leafy vegetable crops such as spinach, lettuce, etc., which are often consumed uncooked or partially cooked. Even when washed, the endosphere remains unaffected. Hence, antibiotic-resistant endosphere bacteria in the vegetables can be problematic when ingested by humans. Apart from causing issues, they can also transfer ARGs to the human gut microbiome through horizontal gene transfer (HGT) via plasmids and mobile genetic elements (MGE) (Rossi et al., 2014; Mafiz et al., 2021). This is a big cause for alarm from one health perspective because studies have shown that consumption of these vegetables is a possible route of ARGs from the soil microbiome to humans (Zhang Y. J. et al., 2019; Mafiz et al., 2021; Rahman et al., 2021). In addition, apart from taking up ARBs, plants can also take up antibiotics directly from the soil amended with manure or irrigated with wastewater (Azanu et al., 2016; Gu et al., 2021; Tadic et al., 2021), which may also exert selection pressure on the plant endosphere microbiome and increase the possibility of the development of a more resistant microbiome, which can be transferred to humans upon consumption. Due to its findings in many studies, the class I integron gene (intI1) and genes encoding transposases are common in harvested vegetables (Freitag et al., 2018; Urra et al., 2019; Zhang Y. J. et al., 2019; Yuan et al., 2022), indicating the possibility of HGT in the phyllosphere. The phyllosphere and rhizosphere may be key areas for HGT in plant and soil habitats because of the high possibility that cells cluster, forming biofilms in the phyllosphere, and bacterial metabolic rates and the mobility of bacteria and MGEs are high in rhizospheres (Chen et al., 2019). Using a functional metagenomic screen of soil-inhabiting bacteria, a significant nucleotide identity (>99%) was observed between resistance cassettes in multidrug-resistant bacteria from soil and those in human pathogens from clinical environments, indicating the occurrence of HGT between these microorganisms (Forsberg et al., 2012). In the screen, two class 1 integrase genes (intI1) from the soil bacteria and clinical pathogens were adjacent to the ARGs, facilitating a shared mechanism of HGT between these two bacterial groups. Class 1 integrons, containing the gene intI1, play an essential role in integrating multiple ARGs on the same genetic locus, generating multidrug resistance in bacterial genomes. The integrons have been observed as prevalent carriers of multiple ARGs in natural and anthropogenically influenced environments (Guo et al., 2017). Based on a study with archived soils, manure applications substantially increased the abundance of soil intI1 (Urra et al., 2019).

The interplay between soil microbiomes, agricultural practices, and human health reveals a critical need to rethink soil and plant management approaches. Harnessing beneficial microbes presents a viable, environmentally sustainable solution to counteract the spread of antibiotic resistance while improving plant productivity. The subsequent discussion focuses on the promising role of these microbes in fostering agricultural sustainability.

One-health synthesis: linking residues, resistance, and mitigation

Antibiotic residues from manure and wastewater often persist in soils at sub-inhibitory levels that both select for resistant bacteria and elevate horizontal gene transfer, including conjugative plasmid transfer across environmental microbiomes. Laboratory work shows that sub-MIC exposures to aminoglycosides, carbapenems, fluoroquinolones, and cephalosporins increase conjugation frequencies, mechanistically supporting resistance exchange at environmental concentrations below MICs. Related studies report fluoroquinolone-driven, dose-dependent increases in RP4 plasmid transfer from E. coli to P. aeruginosa at sub-MICs, highlighting a realistic pathway for ARG dissemination under low-level exposures (Ding et al., 2022). Beyond antibiotics, heavy metals common in agri-food systems (Cu, Zn, Hg, Cd) act as co-selectors that stabilize and enrich ARG-bearing elements even when antibiotic concentrations are low, reinforcing persistence across soil-crop-animal-human interfaces (Shun-Mei et al., 2018). Field evidence from raw-wastewater-irrigated agriculture shows soils with elevated transferable ARGs, including ESBLs, and community functional shifts, documenting an environmental conduit consistent with the mechanistic data (Bougnom et al., 2020).

Actionable implications follow directly. First, benchmark effluents and manures against predicted no-effect concentrations (PNEC) for resistance selection thresholds, which are typically lower than ecotoxicity PNECs; compound-specific PNEC resistance values have been proposed to guide emission limits (Bengtsson-Palme and Larsson, 2016). Where antibiotic-specific data are lacking, a default target of 0.05 μg L−1 has been recommended for antibiotics to minimize selection pressure (Vestel et al., 2022). Second, treated manures in multi-omics field trials show composting reduces total ARGs and resistome risk relative to raw manure, although marker-specific exceptions warrant reporting treatment stage and verifying with sentinel ARGs (Keenum et al., 2021). Together, source control (including co-selectors), evidence-based waste handling, and targeted surveillance at high-risk nodes operationalize a one health response that links mechanistic insight to practical mitigation in agricultural landscapes (Bougnom et al., 2020).

Bioavailability of antibiotics and bioremediation efficacy: exploring the link

The behavior and fate of antibiotics in the environment are not only determined by their physicochemical properties, which include volatility, lipophilicity, water solubility, and sorption capacity, but also determined by various environmental factors, including the different soil properties such as pH, ionic strength, organic matter content, and cation exchange capacity, and the ecological climatic conditions (Figure 2). As a result of these factors, antibiotics can remain in the environment for a short or extended period. Understanding these interactions is essential in assessing the environmental impact of antibiotic residues, particularly in agricultural settings.

Figure 2

Effect of soil parameters on antibiotic bioavailability in soil

Soil pH plays a pivotal role in determining the adsorption and desorption of antibiotics. Studies have shown that the adsorption capacity of antibiotics such as ciprofloxacin and trimethoprim varies with soil pH, indicating that lower pH levels can enhance the mobility of these compounds in the soil environment (Rodríguez-López et al., 2024). The ionic state of antibiotics, influenced by pH, affects their solubility and interaction with soil particles. For instance, acidic conditions can increase the solubility of certain antibiotics, thereby enhancing their bioavailability (Pauletto and De Liguoro, 2024). Conversely, higher pH levels can increase adsorption onto soil particles (Yuan et al., 2024), reducing their bioavailability and potential ecological impact.

Organic matter content is another critical factor affecting antibiotic bioavailability. The presence of organic matter causes the formation of complexes between organic molecules and antibiotic compounds. This interaction leads to a decrease in the mobility of antibiotics, thus reducing their bioavailability to soil microorganisms and plants (Li H. et al., 2024). For example, biochar, a form of carbon-rich organic matter, has been shown to significantly reduce the bioavailability of antibiotics in soil by adsorbing these compounds and preventing their uptake by plants (Pan et al., 2023). The effectiveness of biochar in mitigating antibiotic pollution is attributed to its large surface area and the presence of functional groups that facilitate adsorption (Haider et al., 2024; Jia et al., 2024).

Soil texture, which refers to the size distribution of soil particles, also influences antibiotic bioavailability. Soils with a high clay content typically exhibit greater antibiotic adsorption capacities than sandy soils. This is due to the clay particles’ larger surface area and higher cation exchange capacity, which can bind antibiotics more effectively (Jorge et al., 2024). For instance, studies have demonstrated that clay minerals can significantly influence the retention of antibiotics like tetracycline in soil, affecting their bioavailability and persistence (Li S. Y. et al., 2023). The interaction between antibiotics and soil minerals is complex and can be influenced by factors such as ionic strength and competing ions in the soil solution (Xiao et al., 2023).

Other contaminants, such as heavy metals, can also impact the bioavailability of antibiotics in soil. Heavy metals can compete with antibiotics for adsorption sites on soil particles, potentially altering the adsorption dynamics of antibiotics (Nkoh et al., 2024). Additionally, the co-occurrence of heavy metals and antibiotics can lead to synergistic effects that enhance the persistence of both contaminants in the soil environment (Zha et al., 2023). For example, the adsorption of antibiotics can be influenced by heavy metals, which may either enhance or inhibit the mobility of antibiotics depending on the specific interactions involved (Shu et al., 2025).

Microbial communities in the soil are also affected by the bioavailability of antibiotics. Continuous exposure to antibiotic residues can lead to shifts in microbial community composition, which may affect the degradation and transformation of these compounds (Qiu et al., 2023). The physicochemical properties of antibiotics, such as their hydrophobicity and molecular structure, play a crucial role in determining their bioavailability and the ability of soil microorganisms to degrade them (Nkoh et al., 2024). For instance, antibiotics with higher hydrophobicity tend to adsorb more strongly to soil particles, thereby reducing their bioavailability for microbial degradation (Deng et al., 2024).

Moreover, the dynamics of antibiotic bioavailability in soil are influenced by environmental factors such as moisture content and temperature. Increased soil moisture can enhance the mobility of antibiotics by facilitating their transport through soil pores, while higher temperatures may accelerate the degradation processes (Yang et al., 2024). These environmental conditions can significantly alter the bioavailability of antibiotics, impacting their ecological risks and potential for contaminating groundwater and surface water (Luo et al., 2024).

Linking bioavailability to bioremediation

Bioavailability refers to the extent to which an antibiotic present in soil can be utilized or broken down during bioremediation. When antibiotics are readily accessible, bacteria can degrade them efficiently, thereby contributing to the remediation of soil environments. However, the process may be impeded if they are difficult to access, such as when adhered to soil particles. The increased availability of antibiotics facilitates a more rapid degradation by bacteria, thereby enhancing the efficacy of bioremediation processes. For instance, water-soluble antibiotics present a more accessible option for bacterial utilization and degradation. However, if these antibiotics are firmly adhered to the soil matrix, the accessibility for bacteria diminishes, thereby impeding the remediation process. Research indicates that soil can diminish antibiotic efficacy, resulting in a reduced availability for bacterial interaction.

Bioavailability denotes the degree to which an antibiotic present in soil can be absorbed or engaged with living organisms, especially bacteria. This factor is essential for the process of bioremediation. Bioremediation refers to how microorganisms, particularly bacteria, facilitate the degradation or transformation of environmental pollutants, including antibiotics, into less harmful substances. Antibiotics manifest in multiple forms in the soil environment, whether dissolved in the soil water, adsorbed onto soil particles, or complexed with organic matter. Each of these states significantly influences their bioavailability for bacterial degradation processes.

Antibiotics’ bioavailability is a crucial factor influencing bioremediation efficiency, as bacteria need access to the antibiotics to commence the degradation process. When an antibiotic exhibits high bioavailability, indicating its ready accessibility within the soil solution, bacteria can degrade it effectively, thereby improving the cleanup rates. On the other hand, if it is firmly adsorbed or bound, its bioavailability diminishes, which may impede or restrict degradation processes as fewer bacteria can engage with it.

In addition, antibiotics’ bioavailability directly impacts the rate and efficiency of bioremediation processes. The enhanced bioavailability promotes a more rapid degradation process, allowing bacteria to absorb and metabolize the antibiotic efficiently. For example, antibiotics soluble in water, such as sulfonamides, exhibit greater bioavailability and are consequently more readily degraded by bacterial action. In contrast, less soluble antibiotics like tetracyclines tend to adhere to soil particles, affecting their degradation dynamics, hence, the degradation rate of antibiotics in soil is contingent upon their bioavailability (Cycon et al., 2019). Specifically, adsorbed antibiotics exhibit reduced accessibility for microbial degradation, which may subsequently diminish the efficiency of bioremediation efforts (Hong et al., 2020).

Furthermore, low bioavailability, frequently attributed to robust adsorption to soil constituents, can significantly impede bioremediation efforts by restricting bacterial accessibility. This observation holds significant importance for antibiotics characterized by elevated partitioning coefficients, exemplified by tetracyclines, which tend to associate with soil preferentially. This affinity contributes to their extended persistence and hinders degradation, as discussed by Cycon et al. (2019). Nevertheless, certain bacterial species can surmount low bioavailability by synthesizing biosurfactants or enzymes that promote desorption, thereby augmenting degradation rates. This indicates that the composition and activity of microbial communities play a pivotal role in influencing the effects of bioavailability on bioremediation processes. An intriguing aspect is that low bioavailability may play a role in disseminating ARGs (Li Q. et al., 2024). For example, residual antibiotics in soil, attributed to their low bioavailability, increase the level of soil ARGs by favoring the proliferation of resistant bacterial populations (Chen et al., 2017; Liang et al., 2017), thereby presenting significant ecological risks. The interplay of hindering degradation and the potential dissemination of resistance introduces significant complexities to bioremediation strategies, necessitating meticulous management practices.

Bioremediation efficacy of beneficial bacteria

Antibiotics have been used extensively in agricultural techniques, which has led to the accumulation of these compounds in soil, resulting in significant environmental problems. The existence of these antibiotics is a cause for great concern since it has the potential to result in the development and dissemination of bacteria that are resistant to antibiotics, which poses substantial dangers to the health of both humans and animals (Guo, 2021). At the same time, there has been a growing interest in employing beneficial bacteria for bioremediation to degrade these compounds. This is a practical approach that has attracted a lot of attention. Their roles and limitations for bioremediation must be better understood for effective utilization.

Bacterial bioremediation represents a highly effective, cost-efficient, and environmentally sustainable approach for removing antibiotic contamination from soil environments, utilizing the metabolic capabilities of specific microorganisms to degrade persistent pharmaceutical compounds (Mokrani et al., 2024). The three distinct mechanisms used by beneficial bacteria in bioremediation processes are bioaugmentation, which involves introducing specialized microbial strains or consortia with enhanced biodegradative capacities, biostimulation, which enhances indigenous microbial activity through nutrient supplementation, and bioattenuation, which relies on natural biological transformation processes. Research has demonstrated remarkable success with specific bacterial strains, such as Burkholderia cepacia immobilized on sugarcane bagasse, which effectively degrade tetracycline antibiotics under optimal conditions, including temperatures of 28–43 °C, slightly acidic pH levels (4.5–6.5), and inoculation doses of 15% (Hong et al., 2020). The significance of this approach extends beyond simple contaminant removal, as tetracycline antibiotics, for example, exhibit the highest soil partitioning coefficients among pharmaceutical compounds (Chen et al., 2024), leading to prolonged environmental persistence and serious ecological threats, including alteration of microbial community structures, enhancement of ARG abundance, and bioaccumulation in soil organisms. Furthermore, bacterial bioremediation offers substantial advantages over traditional remediation methods such as adsorption and photocatalytic degradation, which often prove inadequate due to high costs, generation of toxic byproducts, or ecological hazards, making bacterial approaches particularly valuable for addressing the growing environmental challenge of antibiotic contamination that poses long-term threats to ecosystem security and public health.

Mechanisms of bioremediation by beneficial bacteria

Manure and wastewater-related antibiotic pollution of agricultural soils helps ARGs to spread and change microbial ecosystems. By producing degrading enzymes, using antibiotics as a nutrient source, producing biofilms, acquiring biodegrading genes through HGT, and participating in cooperative activities (Figure 3; Table 3), beneficial bacteria help reduce this threat.

Some studies on bacterial bioremediation of antibiotics.

Enzymatic degradation

Enzymatic degradation is a critical process in the bioremediation of antibiotics, where bacteria produce specific enzymes to break down these compounds, making them inert. Bacterial enzymes can break down antibiotic molecules, rendering them inert (Figure 3). The unique genetic composition of the bacterial species involved impacts the efficacy of these enzymes, thereby exposing a complicated relationship between microbial genetics and bioremediation capacity (Elarabi et al., 2023). This method is essential for reducing antibiotic residues in the environment and preventing the spread of antibiotic resistance. For β-lactam antibiotics, such as penicillins, β-lactamases hydrolyze the β-lactam ring, inactivating the antibiotic, with over 890 known variants, including extended-spectrum β-lactamases and carbapenemases (Bush, 2010). Tetracyclines are degraded by enzymes like those encoded by the tetX gene, which are flavoenzymes that inactivate them through oxidation, as shown with environmental isolates in the study by Gasparrini et al. (2020). Aminoglycosides, like kanamycin, are modified by the enzymes acetyltransferases, adenyltransferases, and phosphotransferases, altering their structure to reduce efficacy, with a specific example being a periplasmic dehydrogenase complex that initiates kanamycin deglycosylation (Chen et al., 2023). Another example is Arthrobacter nicotianae, which breaks down tetracyclines (Zhang et al., 2021). General enzymes like oxidoreductases, laccases, and hydrolases are also explored for their role in degrading a broad range of antibiotics, though their specific contributions are less defined (Karigar and Rao, 2011; Bhandari et al., 2021). Understanding these enzymatic mechanisms is crucial for developing effective bioremediation strategies, allowing the selection of appropriate microorganisms or enzymes based on the type of antibiotic and environmental conditions, enhancing cleanup efforts, and reducing environmental impact.

Using antibiotics as a nutrient source

Bacteria can harness antibiotics and various pollutants as nutrient sources, specifically for carbon and energy, which facilitates the degradation of these compounds and mitigates their environmental consequences. This process entails the presence of bacteria that harbor specific enzymes or metabolic pathways capable of degrading antibiotic molecules, thereby utilizing the resultant degradation products for their growth and proliferation. For example, Pseudomonas fluorescens has been documented to utilize oxytetracycline as its exclusive carbon source, fully mineralizing it into carbon dioxide and water (Egorov et al., 2018). Comparably, Pseudomonas putida can degrade penicillin-G through hydrolysis, forming penicilloic acid and phenylacetic acid. This microbe subsequently employs phenylacetic acid as a carbon source (Al-Ahmad et al., 1999). This mechanism is similarly relevant to a range of pollutants, including petroleum hydrocarbons, where bacteria like Pseudomonas putida employ these compounds as carbon sources for their growth, illustrating a well-documented bioremediation strategy (Cui et al., 2020). The application of this nutrient presents significant benefits for bioremediation, as it leverages the natural metabolic processes of bacteria to restore contaminated environments, particularly those impacted by antibiotic-laden wastewater or soil. By meticulously selecting or engineering bacterial strains that exhibit distinct degradation pathways, it is possible to formulate bioremediation strategies specifically designed to target particular pollutants. For example, studies have effectively isolated bacterial strains capable of degrading sulfonamides, fluoroquinolones, and other antibiotics, using these compounds as carbon sources, which enhances remediation efforts (Fu et al., 2022; Wang et al., 2023; Zhang M. et al., 2023; Rodrigues et al., 2025; Zhu et al., 2025) (Table 3).

Nevertheless, one must consider the significant challenges, including the specificity exhibited by various bacterial strains toward certain antibiotics and the potential to spread ARGs. It is essential to recognize that not all antibiotics function as suitable carbon sources. The effectiveness of this application depends on the distinct chemical composition of the antibiotic involved, alongside the specific bacterial strain under investigation. Moreover, bacteria that possess resistance mechanisms, such as the production of beta-lactamases, can transfer resistance genes to other microorganisms in their surroundings, thus posing considerable threats to ecological systems (Markley and Wencewicz, 2018). Ongoing research endeavors are concentrated on enhancing this methodology, exploring the domain of genetic engineering to augment degradation efficiency while considering the possible risks associated with resistance.

Biofilm production

Biofilms, complex communities of microorganisms, play a significant role in bioremediation by degrading a wide range of environmental contaminants, such as petroleum hydrocarbons and heavy metals, due to their resilience to harsh conditions like toxic chemicals, desiccation, and UV radiation, as supported by studies like Ian W. Sutherland’s work on biofilm exopolysaccharides (Sutherland, 2001). Their extracellular matrix contains functional groups that bind and immobilize hydrophobic compounds, facilitating degradation, as shown in the study by Mangwani et al. (2016), making them suitable for cleaning up contaminated sites, as noted by Das and Dash (2014). Natural attenuation, where indigenous microbes degrade contaminants without intervention, can be slow, especially in newly contaminated sites (Sara, 2003), but can be accelerated through biostimulation, adding nutrients like nitrogen or carbon, and bioaugmentation, introducing specific degradative microorganisms (Tyagi et al., 2011; Sonawane et al., 2022). Additionally, changes in biofilm physiology and morphology can detect contaminants, such as heavy metals, microplastics, and other pollutants in water (Syed et al., 2021; Luo et al., 2022), serving as indicators, offering a promising approach for bioremediation with ongoing research focused on optimizing these processes.

Consortia mechanisms

Microbial consortia, defined as cooperative assemblies of microorganisms, play a crucial role in bioremediation by collaboratively degrading environmental pollutants that individual strains may struggle to address (Cieplik et al., 2019) (Figure 4). Their effectiveness is attributed to their ability to participate in diverse metabolic processes, which enables them to adjust to complex combinations of pollutants and varying environmental circumstances, as evidenced by studies showing enhanced degradation rates in areas impacted by oil contamination (Valentine et al., 2010). For instance, naturally occurring bacterial consortia, exemplified by Alcanivorax borkumensis, have been instrumental in the bioremediation efforts following the Deepwater Horizon oil spill in 2010, resulting in a notable decrease in the environmental repercussions of crude oil. The collaborative endeavors evident within these consortia manifest in diverse manners, enhancing their potential for bioremediation. Some microorganisms are recognized for their ability to synthesize biosurfactants, such as rhamnolipids, which emulsify hydrophobic pollutants like oil, thus improving their bioavailability for degradation by other constituents of the microbial community (Zeng et al., 2018). Sequential degradation serves as a crucial mechanism within microbial ecology, where an initial microorganism commences the breakdown of a pollutant, thereby enabling a subsequent organism to complete the degradation process. An illustrative example can be found in the bioremediation of polychlorinated biphenyls, where anaerobic bacteria first engage in dechlorinating these compounds, after which aerobic bacteria mineralize the resulting intermediates (Lin et al., 2024). This collaborative methodology enables a more comprehensive dissection of complex pollutants, surpassing the efficacy of singular strains.

Figure 4

Engineered microbial consortia are presently being developed to target pollutants precisely, thus offering tailored bioremediation solutions. For example, studies have demonstrated that a consortium of Pseudomonas putida and Acinetobacter sp. achieved enhanced phenol degradation rates compared to either strain alone, highlighting the benefits of combining complementary metabolic pathways (Xu et al., 2024). These methodologies present considerable promise for addressing emerging contaminants, such as pharmaceuticals and pesticides, especially in cases where natural consortia may demonstrate insufficient activity. Despite these advantages, challenges remain in applying microbial consortia for bioremediation efforts. It is essential to ensure the stability of a consortium when faced with fluctuating environmental conditions, as competition among its members or changes in the environment can greatly compromise cooperative interactions (Bernal and Llamas, 2012). Moreover, it is imperative to contemplate the possibility of propagating antibiotic resistance genes or other unfavorable traits within the consortium, which could result in ecological consequences (Piazza et al., 2019). Such challenges necessitate careful supervision and strategic administration to ensure effectiveness and safety. In considering the trajectory of future advancements, it is evident that the domains of synthetic biology and genomics are poised to revolutionize the approaches utilized in the design and optimization of microbial consortia. Researchers can develop more efficient and manageable bioremediation strategies by engineering microbes to exhibit specific degradation pathways or enhance their cooperative behaviors through genetic modifications (Singh et al., 2011). The engineering of synthetic consortia is designed to degrade a broader spectrum of pollutants, thus offering scalable methodologies for environmental remediation.

Molecular methods versus established bioremediation technologies

Targeted molecular tools such as CRISPR-Cas systems delivered by bacteriophages or conjugative plasmids can selectively remove ARGs or be used to control ARG-carrying hosts (e.g., plasmid curing or sequence-specific killing), offering precision with minimal collateral damage to non-targets when delivery succeeds. Proof-of-concept studies show >99.9% elimination of targeted resistant E. coli in vivo using conjugative CRISPR-Cas9 in the gut microbiota (Neil et al., 2021), phage-delivered CRISPR that degrades plasmid-borne ARGs without killing hosts (Tao et al., 2022), CRISPR systems (e.g., VADER) that degrade ARGs in wastewater matrices (Li X. et al., 2023), and engineered anti-biofilm phages that outperform wild-type phages in vitro and reduce intestinal E. coli in animals (Gencay et al., 2024). However, soil deployment remains nascent: reviews emphasize delivery barriers in complex matrices, risks of escape mutants/off-target effects, and biosafety/regulatory uncertainties, arguing that near-term use is likeliest in contained nodes (e.g., digesters, WWTPs) rather than open soils (Mayorga-Ramos et al., 2023).

By contrast, established feasible treatments are field-ready but less specific. Manure composting often reduces ARG loads and resistome risk relative to stockpiling, though marker-specific rebounds can occur; performance depends on temperature profiles and process control (Keenum et al., 2021; Sun et al., 2024; Wang G. et al., 2024). Biochar amendments can sorb antibiotics, shift microbial communities, and lower ARG abundances in soil-crop systems, but long-term persistence and trade-offs remain under study (Choi et al., 2024; Li H. et al., 2024). Advanced oxidation processes (AOPs) such as ozonation, UV/H₂O₂, and photocatalysis efficiently remove antibiotics in water (Cuerda-Correa et al., 2020; Zhang Y. et al., 2022; Pastor-Lopez et al., 2024) and, in some cases, reduce ARB/ARGs, making them suitable upstream of land application; however, limitations include energy cost and by-product control, and they are not directly applicable in soils. Overall, gene-editing tools are promising and precise but currently best suited to contained treatment applications; composting/biochar/AOPs remain deployable at scale for agricultural settings, with method choice governed by matrix (manure, soil, wastewater), cost, and risk targets (Mayorga-Ramos et al., 2023).

Regulatory considerations and practical challenges on the application of beneficial microbes in bioremediation

Bacterial bioremediation can help clean antibiotic-polluted farm soils, but it has significant regulatory and practical challenges. Tight rules on genetically modified organisms (GMOs), different ways to manage antibiotics, and ecological uncertainties make deployment tricky. Practical challenges like microbial survival, cost-effectiveness, and soil variability limit scalability. Hence, we examine barriers, highlighting their impact on microbial solutions and the need for integrated strategies to realize the bioremediation potential of beneficial bacteria.

Regulatory frameworks for antibiotic use and microbial bioremediation vary widely from country to country and region to region, creating uneven landscapes for implementation. In the European Union (EU), strict regulations, such as Regulation (EU) 2019/6, have banned antibiotic growth promoters in livestock since 2006 (Topp et al., 2018; Mdegela et al., 2021; Farrukh et al., 2025). However, therapeutic use remains high, with 131 mg/kg of poultry biomass treated annually, maintaining ARG hotspots (Checcucci et al., 2020). In regions like South Asia and parts of Africa, lax oversight allows subtherapeutic dosing, with up to 70% of veterinary antibiotics excreted unchanged, boosting soil ARG loads by 103 copies/g (Muhammad et al., 2020). This disparity hampers consistent bioremediation strategies, as bacterial strains face different antibiotic pressures in their immediate environments.

Also, the regulations surrounding genetically modified organisms impose additional constraints on using CRISPR-edited bacterial strains. The European Union’s Directive 2001/18/EC categorizes CRISPR-modified strains as GMOs (Okoli et al., 2022), necessitating extensive risk assessments and public approval processes. This affects the benefits of this technology. For example, the field trials of Pseudomonas with a silenced intI1 gene were postponed, notwithstanding the success observed in laboratory settings (Ferreira et al., 2023). On the other hand, the USDA’s streamlined process under the “SECURE Rule” permits certain gene-edited microbes to bypass GMO labeling in the United States, provided that no foreign DNA is present. This facilitates pilot tests of Bacillus subtilis that have been enhanced with the tetX gene (Kim et al., 2023). In developing nations, it is evident that regulatory frameworks frequently exhibit significant deficiencies, thereby posing a risk of uncontrolled release and subsequent ecological damage. Achieving coherence among these policies has the potential to establish a standardized approach to safe deployment, however, one must acknowledge the ongoing political and economic obstacles.

In addition, the cost of production is a major barrier to widespread adoption. Smallholder farmers, common in developing regions, often lack access to expensive technologies needed for production. Around 80% rely on manure without remediation (Muhammad et al., 2020). Scaling requires reducing costs, such as optimizing bioreactor yields (101⁰ CFU/mL) or using local isolates, but infrastructure gaps remain. Soil variability makes scaling even more challenging. For example, sadA-expressing Pseudomonas degraded SMX 70% faster in acidic loams (pH 5.5, 5% organic matter) than in neutral clays (pH 7, 10% organic matter) due to sorption issues (Rodríguez-López et al., 2024). Also, in another study, field trials across ten sites showed consortia efficacy ranging from 20 to 80% in ARG reduction, linked to specific microbial interactions in the soil (Wang S. et al., 2024). Hence, tailoring strains to local conditions through omics-guided selection could enhance results, but this requires extensive regional data and adaptive formulations, which are expensive.

Finally, addressing these challenges needs integrated strategies. These strategies can transform lab research into practical applications, but coordinated efforts across microbiology, policy, and agriculture are crucial.

Conclusion and future recommendations

This review has comprehensively examined the challenges of antibiotic contamination in agricultural soils and the promising potential of beneficial bacteria in bioremediation. By detailing the complex sources of antibiotic pollution, the influence of soil parameters on antibiotic bioavailability, and the mechanisms by which microbial consortia can degrade antibiotics (e.g., enzymatic biodegradation, biofilm formation, and cooperative metabolism), the manuscript demonstrates how integrating molecular insights with practical remediation strategies can address both ecological and public health concerns. The discussion underscores that despite the encouraging laboratory-scale findings, challenges such as scalability, cost-effectiveness, and potential environmental risks associated with deploying engineered microbes persist.

The symbiotic association between plants, soil, and beneficial microbes has been shown to play a pivotal role in bioremediation and plant health improvement. However, a lot of information is still missing to make more positive developments from these interactions. A good bioremediation strategy involves a well-designed and targeted approach involving various approaches to achieve sustainable bioremediation (Figure 4). For full acceptance of beneficial microbes in bioremediation and sustainable agriculture, more insight is needed into the comprehensive tripartite interactions between plants, microbes, and their environment. Knowledge of microbial functions for bioremediation purposes is also very critical. Identification of candidate genes involved in antibiotics degradation and their characterization are necessary to allow for possible manipulation and editing of these genes for improved bioremediation potential and plant health promotion. Several regulatory mechanisms should also be looked into regarding genetically modified organisms for the safety of potential bioremediation potentials in the environment, since they will be deployed in the field to ascertain their potential fully.

At the center is the core objective of sustainable antibiotic bioremediation. Surrounding this are key components: (1) Optimized Microbial Consortia—featuring multi-functional degrader bacteria engineered for complementary metabolic capabilities, (2) Plant-Microbe Partnership Systems—emphasizing rhizosphere engineering to enhance plant-microbial synergies in the root zone, (3) Bioavailability Optimization Strategies—focusing on soil amendment design that considers pH, clay content, organic matter, and moisture effects, (4) Monitoring and Assessment—employing metagenomic surveillance to track antibiotic resistance genes and remediation progress, (5) Genetic Engineering Tools—utilizing CRISPR-based systems for enhanced degradation capabilities, and (6) Regulatory and Policy Framework—implementing a One Health approach aligned with Sustainable Development Goals 2 (Zero Hunger), 3 (Good Health and Well-being), and 15 (Life on Land).

Looking forward, future research should prioritize a few key areas. First, experimental approaches must be refined to quantify better how specific soil properties (pH, organic matter, texture) modulate antibiotic persistence and degradation rates, leveraging advanced metagenomic and metabolomic tools. Second, further characterization and optimization of microbial consortia, potentially through synthetic biology and gene editing, will be crucial in enhancing bioremediation efficacy while ensuring biosafety. Third, extensive field trials under diverse agricultural conditions are needed to validate laboratory findings and to tailor remediation strategies to local contexts. Finally, harmonizing regulatory frameworks internationally, supported by comprehensive risk assessments and stakeholder engagement, is essential to safely advance the application of natural and engineered microbial remediation methods (Figure 4). These integrated strategies can significantly contribute to sustainable agriculture and environmental protection under a One Health framework by bridging molecular-level research with policy and field implementation.

To chart a path forward, we propose key unanswered questions that can bridge laboratory insights and field realities. These targeted research priorities will help focus efforts on linking soil properties, microbial dynamics, and stakeholder needs for effective, scalable bioremediation.

  • How do combined soil parameters, i.e., pH, organic matter, and texture, interact to modulate in situ degradation rates of distinct antibiotic classes?

  • Which native microbial consortia optimize the co-degradation of multi-class antibiotic occurrences under field conditions?

  • What is the extent of horizontal gene transfer of ARGs during bioaugmentation with introduced versus indigenous bacteria?

  • How does plant–microbe–soil feedback influence the long-term stability of bioremediation efficacy and crop uptake of antibiotic residues?

  • What socio-economic factors most strongly predict smallholder farmer adoption of microbial bioremediation technologies?

  • Can metagenome-informed predictive models accurately forecast bioremediation outcomes across diverse agroecosystems?
