principle of microbial fuel cell Electrochem Commun 8:489–494. For example, if a microbial fuel cell were to reduce carbon dioxide to make electricity, not only would there be a renewable source of fuel, but the excess carbon dioxide put into the atmosphere by burning fossil fuels could be used. Moreover, as denitrification uses the electrons obtained from the separate oxidation of organic matter present in the wastewater, the MFC system can operate very efficiently at low COD/N ratios. Application of microbial fuel cells (MFCs) to wastewater treatment for direct recovery of electric energy appears to provide a potentially attractive alternative to traditional treatment processes, in an optic of costs reduction, and tapping of sustainable energy sources that characterizes current trends in … ACS Appl Mater Interfaces 7:20657–20666. doi: Deval AS, Parikh HA, Kadier A, Chandrasekhar K, Bhagwat AM, Dikshit AK (2016) Sequential microbial activities mediated bioelectricity production from distillery wastewater using bio-electrochemical system with simultaneous waste remediation.

For this reason, there is no industrial application of MFC to date. In contrast, electrode-oxidizing organisms use electrons from the cathode to reduce substances in the cathode chamber. Synthetic biology may help in developing robust exoelectrogens with perfect electron-exchange properties. These types of studies should identify ways to optimize the reactions to get the most energy from the bacteria. 24) were performed with D. desulfuricans and concerned with the effects of H2S removal and type of provided carbon source on the current production (Cooney, Roschi, Marison, Comninellis, & von Stockar, 1996). doi: Venkata Mohan S, Chandrasekhar K (2011a) Self-induced bio-potential and graphite electron accepting conditions enhances petroleum sludge degradation in bio-electrochemical system with simultaneous power generation. A multitude of choices may be made for the nature of the catalyst at the anode and the cathode as well as the reducing power and the membrane, some of which are indicated. The anode of a microbial fuel cell is not a natural electron acceptor, and thus it is unlikely that there has been significant selective pressure on Geobacter species to optimize current production under the conditions found in microbial fuel cells (Lovley, 2006a). doi: Evelyn Li Y, Marshall A, Gostomski PA (2014) Gaseous pollutant treatment and electricity generation in microbial fuel cells (MFCs) utilising redox mediators. Many researchers have started focusing on the ability of microorganisms to produce electric energy in biological systems (Potter, 1910). © 2020 Springer Nature Switzerland AG. Biofuel Res J 1:7–15. A review. Applied interest in microbial fuel cells also arises from the idea of an environmentally sustainable production of chemical commodities, e.g., from waste (Logan & Rabaey, 2012; Lovley & Nevin, 2013). Israel-based company, Emefcy, named as a play on the acronym for microbial fuel cell (MFC), starts with the same principle as most wastewater treatment—water is aerated so … Bioresour Technol 97:621–627.

Because of unlimited availability and positive redox potential, oxygen is mostly widely considered as the favorable electron acceptor for practical applications. Trends Biotechnol 29:41–49. In fact, biofuel cells with a power density greater than 1 mW/cm2 may already be powerful enough for cellular phone chargers [133]. However, these amounts of electric energy are typically sufficient to power small devices such as radio sensors or meteorological buoys in remote areas and the deep ocean (Tender et al., 2008; Thomas et al., 2013). Every fuel cell has two electrodes called, respectively, the anode and cathode. More recently, microbial fuel cells employing SRB have been used to test coupling of sulphur pollutant removal with the generation of electricity. There may be significant potential for increasing the current output of microbial fuel cells via strain selection/design (Izallalen et al., 2008; Yi et al., 2009). 2010.

The use of microbial fuel cells is still not optimized, and the level of electric current generated by such systems is low, but the potential for such systems is great. Table 5 summarizes the general performance of typical biofuel cells reported so far. As a result, a lifetime of months or years is typically expected of, Metabolite quantification detected accumulation of isopentenyl pyrophosphate, indicating that NudB was a bottleneck enzyme in engineered heterologous MVA pathway. An enzyme's lifetime can be extended upon immobilization. Additionally, to increase the voltage of the cell, permanganate, dichromate, peroxide, and ferricyanide are being used as a part of MFCs in light of their high redox potential (Yang et al., 2011). Wiley-Interscience, Hoboken. Performance of typical biofuel cells reported recently. In the near future, MFCs might be developed to such a phase, to the point that they can give a sensible and usable power yield per unit the MFC volume.
