“…Iron powder treatment was found to be effective in enhancing electricity generation in MFCs by lowering the redox potential and promoting the growth of anaerobes [39]. Generally, exo-electrogenic bacteria can reduce Fe (III), and Desulfobulbus uses both sulfate and Fe (III) as an electron acceptor [40].…”

This study explores the complex relationship between soil electricity generating capacity, bacterial community dynamics, and soil chemical and physical properties across diverse regions of Japan. First, soil samples were systematically collected and analyzed. Subsequent investigations evaluated soil microbial biomass carbon, dissolved organic carbon (DOC), and total dissolvable iron (DFeT) concentrations. In the experiments, soil samples underwent a rigorous 60-day microbial fuel cell trial, wherein power density and total energy output were measured. Significant variations in power density were observed among different soil samples; specifically, a sugarcane field designated as Okinawa-3 and a peach orchard soil as Nagano-2 demonstrated relatively high total energy output. Analysis of soil bacterial community structures identified some families which showed positive correlations with increased electricity generation capabilities. Correlation analyses revealed associations between these bacterial communities and key soil parameters, particularly with DOC and DFeT concentrations. Redundancy analysis revealed intricate connections between soil properties and electricity generation capacities. Particularly noteworthy was the positive correlation between Acidobacteriaceae and DOC, as well that between Sphingomonadaceae and electricity generation, highlighting the crucial roles of soil microbial communities and chemical compositions in driving electricity generation processes.

“…They also reported that the surface of the modified anode was rough and bacteria were evenly attached on the whole surface of anode as compared to unmodified anode. Matsumoto et al 30 reported that the power output (130 mW/m 2 ) by using ZVI‐based anode was three times higher than unmodified anodes (43 mW/m 2 ) in rice paddy‐field MFCs. The oxidation/reduction reactions around the anode lowered because ZVI activates the aerobic microbes.…”

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.
