Climate Change and Soil Microbial Control of Carbon Sequestration
Soil microbe, as the primary regulator for soil organic carbon (SOC), plays an important role in various of biochemical reactions. Energy exchanges across ecosystems and trophic levels are fundamental modes of interactions. A new viewpoint refers to that the organic matter entering soil is mostly utilized by microbes as energy instead of as a carbon (C) source. Although microbial biomass represents merely 1%–3% of SOC, microbes drive the oxidation-reduction cascade processes changing the state of C oxidation, which is associated strongly with the energy storage capacity. With this energy applied to soil, the C cycle-related energy conversion is evident due to the plant storage of organic C energy through the chemical bonding between organic compounds, which can subsequently be utilized by microbes within food webs. Therefore, partial control of energy content along with fluxes in soil is achieved by the same processes as in the case of SOC (such as accumulation and mineralization). However, the microbial energy metabolism guaranteeing the soil functioning is still unknown.
During the past several decades, there have been intensive explorations focusing on the impact of soil microbes on C cycling. The emphasis on investigating the global C cycle due to its association with microbes led to a growing number of studies concerning microbes. In addition, it has been universally acknowledged that the microbial involvement determines the extent of soil SOC reservoir, because the soil C dynamics ultimately originate from the growth and activity of microbes. Nevertheless, the effect of microbial energy metabolism on soil C stabilization remains elusive.
This Research Topic of Frontiers in Environmental Science-Soil Processes emphasizes soil carbon sequestration along with microbial energy metabolism. We welcome Brief Research Report, Hypothesis & Theory, Methods, Revision, Editorial, Data Report, Mini Review, Opinion, Policy and Practice Reviews, Policy Brief, Review, Systematic Review, Original Research, Perspective, Technology and Code for submission to this research topic. Papers proposing innovative models or approaches within environmental sciences, microbial ecology and soil science are also welcome. We encourage submissions involving transdisciplinary associated research areas covering plant science, soil science, ecology, agricultural meteorology, agronomy, environmental science and climate change biology, opening novel avenues for microbial carbon understanding.
Topics of interest for this Research Topic include, but are not limited to:
1. How microbial energy flows and stores in the forms of soil organic carbon;
2. Soil carbon dynamics and flux in microbial network;
3. Soil microbial energy metabolism during carbon sequestration;
4. The function and structure of soil microbes in carbon sequestration;
5. The new methods explore the energy to soil organic carbon;
6. Interactions among soil microbial community function.
