“…is added [63]. Pure cultures capable of producing current in a MFC include representatives of the Firmicutes [64] and Acidobacteria [65], four of the five classes of Proteobacteria [59,[66][67][68][69][70][71][72] as well as the yeast strains Saccharomyces cerevisiae [73] and Hansenula anomala [74]. These organisms interact with an anode through a variety of direct and indirect processes producing current to varying degrees.…”

Microbial fuel cells (MFCs) are devices that can use bacterial metabolism to produce an electrical current from a wide range organic substrates. Due to the promise of sustainable energy production from organic wastes, research has intensified in this field in the last few years. While holding great promise only a few marine sediment MFCs have been used practically, providing current for low power devices. To further improve MFC technology an understanding of the limitations and microbiology of these systems is required. Some researchers are uncovering that the greatest value of MFC technology may not be the production of electricity but the ability of electrode associated microbes to degrade wastes and toxic chemicals. We conclude that for further development of MFC applications, a greater focus on understanding the microbial processes in MFC systems is required.

“…The E. coli being a major group was likely because the soil was from a farmland which was fertilized with manure. The enrichment of E. coli on the anode was due to extracellular electron transfer (Zhang et al, 2008;Qiao et al, 2009). The number of clones with > 97% similarity to Deltaproteobacteria was 5 from the anode and 2 from soil.…”

There is limited information about the factors that affect the power generation of single-chamber microbial fuel cells (MFCs) using soil organic matter as a fuel source. We examined the effect of soil and water depths, and temperature on the performance of soil MFCs with anode being embedded in the flooded soil and cathode in the overlaying water. Results showed that the MFC with 5 cm deep soil and 3 cm overlaying water exhibited the highest open circuit voltage of 562 mV and a power density of 0.72 mW m −2 . The ohmic resistance increased with more soil and water. The polarization resistance of cathode increased with more soil while that of anode increased with more water. During the 30 d operation, the cell voltage positively correlated with temperature and reached a maximum of 162 mV with a 500 Ω external load. After the operation, the bacterial 16S rRNA gene from the soil and anode was sequenced. The bacteria in the soil were more diverse than those adhere to the anode where the bacteria were mainly affiliated to Escherichia coli and Deltaproteobacteria. In summary, the two bacterial groups may generate electricity and the electrical properties were affected by temperature and the depth of soil and water.

“…4A), implying that current production is beneficial for the survival of antibiotic resistant E. coli, likely because they have the opportunity to respire the anode electrode during electricity generation. Previous studies have demonstrated that E. coli release electron shuttles to the anode electrode for extracellular electron transfer (Zhang et al, 2006;Zhang et al, 2008). Moreover, prior research indicates that E. coli is likely capable of using electron shuttles released by exoelectrogens (e.g., riboflavin) for respiration Wang et al, 2014).…”
