“…Adding an external carbon source, such as glucose or compost, performance of terrestrial MFC electroactive bacteria can significantly improve [ 21 , 104 , 105 , 106 ]. Among abiotic factors, water content is another key limiting parameter for an appropriate functioning of this technology [ 107 ].…”

Electroactive bacteria (EAB) are natural microorganisms (mainly Bacteria and Archaea) living in various habitats (e.g., water, soil, sediment), including extreme ones, which can interact electrically each other and/or with their extracellular environments. There has been an increased interest in recent years in EAB because they can generate an electrical current in microbial fuel cells (MFCs). MFCs rely on microorganisms able to oxidize organic matter and transfer electrons to an anode. The latter electrons flow, through an external circuit, to a cathode where they react with protons and oxygen. Any source of biodegradable organic matter can be used by EAB for power generation. The plasticity of electroactive bacteria in exploiting different carbon sources makes MFCs a green technology for renewable bioelectricity generation from wastewater rich in organic carbon. This paper reports the most recent applications of this promising technology for water, wastewater, soil, and sediment recovery. The performance of MFCs in terms of electrical measurements (e.g., electric power), the extracellular electron transfer mechanisms by EAB, and MFC studies aimed at heavy metal and organic contaminant bioremediationF are all described and discussed.

Summary The employment of soil microbial fuel cells (SMFCs) has become popular recently due to it's dual properties of energy production and soil pollutants treatments. In SMFCs, the main problem is to attract the exoelectrogens to the anode in solid medium rather than in aqueous medium of MFCs. So, the subsequent research should focus on developing anode materials that can not only promote the aggregation of exoelectrogens, but also cost‐effective, and so as to facilitate the removal of pollutants from contaminated soils and the power generation for low energy accessories. Recent studies have reported that the modification of traditional anode materials makes the SMFCs to obtain excellent performance, especially the use of renewable raw materials. This review summarizes the advancements of biochar, metals, graphene (Gr), carbon nanotubes (CNTs) and their derivatives as anode materials in SMFCs. Furthermore, the performance improvements of SMFCs by using the novel or possible future anode materials in the removal of pollutants and shifting of bacterial community were described. Finally, the future trends of anode materials for SMFCs were prospected. Novelty statement The short of comprehensive review on the anodic materials limited the research and application of SMFCs. This work not just summarized the current used anodic materials, but also highlighted the possible future anodic materials, which should be helpful for comprehensive understanding and be beneficial to advance future research on SMFCs.
