“…The bacterial library (58 clones sequenced in total) contained three phylotypes belonging to two phyla: Firmicutes (52 clones, 90% of the clones analyzed) and Thermodesulfobacteria (6 clones, 10% of the clones analyzed). In comparison with the anodic consortia of mesophilic and thermophilic MFCs, [16][17][18] the anodic consortium of the hyperthermophilic MFC showed limited diversity. Sequences related to known exoelectrogenic microorganisms were not detected.…”

We examined whether a hyperthermophilic microbial fuel cell (MFC) would be technically feasible. Two-chamber MFC reactors were inoculated with subsurface microorganisms indigenous to formation water from a petroleum reservoir and were started up at operating temperature 80 °C. The MFC generated a maximum current of 1.3 mA 45 h after the inoculation. Performance of the MFC improved with an increase in the operating temperature; the best performance was achieved at 95 °C with the maximum power density of 165 mWm−2, which was approximately fourfold higher than that at 75 °C. Thus, to our knowledge, our study is the first to demonstrate generation of electricity in a hyperthermophilic MFC (operating temperature as high as 95 °C). Scanning electron microscopy showed that filamentous microbial cells were attached on the anode surface. The anodic microbial consortium showed limited phylogenetic diversity and primarily consisted of hyperthermophilic bacteria closely related to Caldanaerobacter subterraneus and Thermodesulfobacterium commune.

“…Studies are demonstrating that any compound degradable by bacteria can be converted into electricity [20]. The range of compounds include, but by no means limited to, acetate [21,22], glucose [23], starch [24], cellulose [25], wheat straw [26], pyridine [27], phenol [28], p-nitrophenol [29] and complex solutions such as domestic waste water [30,31], brewery waste [32], land file leachate [33], chocolate industry waste [34], mixed fatty acids [35] and petroleum contaminates [36]. Within these systems less biomass is also generally produced then their equivalent aerobic processes and without the need for an energy intensive aeration process less energy is required [7].…”

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.

“…These microbes help in degrading the organic pollutant present in the wastewater. Phenol is a very common effluent coming out of industries, including polymeric resin production, coal gasification, pharmacy, fertilizers and other chemicals [6]. Phenol can be toxic to aquatic organisms at a concentration beyond 5 mg/liter and gives an objectionable taste to drinking water at far lower concentrations.…”
