About this Research Topic
A wide range of solid materials have been tested for improving the efficiency of biological conversions in treatment and recovery of resources from wastewater and on site bioremediation. Most of the applications rely on their capacity to act has electron shuttles (or redox mediators) facilitating electron transfer to and from bacteria and thus accelerate biological conversions. It has also been proposed that solid materials can facilitate direct interspecies electron transfer, which can potentially be more effective than mediated interspecies electron transfer that rely on the diffusion of metabolites generated by one organism and consumed by other. In addition, other interactions related to materials surface morphology/chemistry, absorption capacity and conductivity may improve biological conversions by stimulating microbial growth and/or activity. Current research focus on the development of modified materials to improve the interaction material-microorganism in several biotechnological applications. Efficient developments on this area requires a deeper understanding of the mechanisms underneath the specific required interactions.
This Research Topic aims at providing the readers with insights on the complex interactions occurring between the biological interface (microorganism) and material interface in environmental biotechnology processes. We welcome original research articles, reviews and perspectives highlighting the current advances in our understanding of the microbial-material interactions and the progresses on microbial-material interactions based applications.
More specifically, this Research Topic will cover:
-Impacts of (engineered) materials on microbial community structure and function
-Mechanisms of interaction between microorganisms and materials
-Molecular aspects of microorganisms-materials interaction
-Novel and modified materials for improved biological conversions
-Novel biotechnological applications of (engineered) materials for improved biological conversions
Keywords: Materials, Catalytic redox activity, Electrical conductivity, Biostimulation
