The mechanism of electron transfer can occur by three different pathways (Fig. Compared to the performance of biofuel cells two decades ago, the power density of newly developed biofuel cells was about 1–2 orders of magnitude higher [52, 97, 124, 132]. Accordingly, microbial biofuel cells are preferred for the applications where the volume and weight of cells are not of concern; while enzymatic fuel cells can be designed to supply power for compact devices. Enzymatic biofuel cells often last from hours to days [44, 47, 130]. Ralf Rabus, ... Inês A.C. Pereira, in Advances in Microbial Physiology, 2015. Environ Sci Technol 40:5181–5192.

In most cases, the stability of biocatalysts is largely the determining factor. MFCs are one of the widely studied technologies that have potential for waste valorization into energy in the form of bioelectricity production (Koók et al., 2016). Among the few materials used for the electrodes, carbon-based materials, like graphite and carbon with metal-based impregnations or coatings, were observed to be economical and proficient for bioelectricity production (Xie et al., 2010; Mohanakrishna et al., 2012). doi: Rismani-Yazdi H, Carver SM, Christy AD, Tuovinen OH (2008) Cathodic limitations in microbial fuel cells: an overview.

ED glycolysis increased only lightly despite its ability to generate both NADPH and acetyl-coA for fatty acid synthesis, making ED glycolysis a potential target for metabolic improvement, GC-MS, steady-state isotopic labeling, 13C MFA, Increased carbon and redox demands of mevalonate over production were met by conversion of NADH to NADPH via transhydrogenase. Combined overexpression of glucose-6-phosphate dehydrogenase and 6-phosphogluconolactone resulted in the highest PPP flux and the highest expression levels of recombinant protein, Flux modeling of central carbon metabolism verified the absence of ED glycolysis and oxidative PPP and showed high TCA cycle flux, Flux modeling of central carbon metabolism revealed noncanonical TCA cycle reactions, generation of C1 from pyruvate, and isoleucine production via citramalate synthase, GC-MS, parallel steady-state isotopic labeling, 13C MFA, Flux modeling of central carbon metabolism showed that the TCA cycle and oxidative PPP are responsible for NADPH production during growth on xylose, 13C fingerprinting based on labeling patterns of only a few amino acids was used to assess the metabolic activity of EMP and ED glycolysis, gluconeogenesis, glyoxylate shunt, anaplerotic pathways, and amino acid synthesis in a nonmodel organism, GC-MS, parallel steady-state isotopic labeling, 13C fingerprinting, Expression of heterologous xylose reductase (XR), xylitol dehydrogenase (XDH), and xylulose kinase enzymes led to increased flux through the oxidative PPP and TCA cycle to meet increased NADPH and energy demands, limiting ethanol production, GC-MS, steady- state isotopic labeling, 13C MFA, Yeast strain with xylose isomerase (XI)-based xylose assimilation did not exhibit high flux through oxidative PPP suggesting that XI ameliorates the redox imbalances seen in XR-HDH strains. In comparison to a standard hydrogen electrode, this fuel cell produces −400 mV. Thus, living microbes are advantageous since they have the ability to reproduce. In this chapter, the theories underlying the electron transfer mechanisms, the biochemistry and the microbiology involved, and the material characteristics of anode, cathode, and the separator have been clearly described. Advances in the understanding of the microorganisms have increased the efficiency for the reactions. This chapter highlights the major factors involved toward the improvement bioelectricity production processes. Further, conductive materials comprising living bacteria are self-renewing because bacteria can self-repair and replicate. Metabolomic analysis identified increased NADPH availability leading to reduced acetate production as a major source of improvement, Increased carbon and redox demands of fatty acid over production resulted in increased flux through the oxidative PPP and increased conversion of NADH to NADPH by transhydrogenases. In some instances, bacteria form a thick film on the cathode, so it may be the pili or nanowires that transmit the electrons to the anode. Stabilizing the baseline current of a microbial fuel cell-based biosensor through overpotential control under non-toxic conditions. Review. Environ Sci Technol 40:2426–2432. At its core, the MFC is a fuel cell, which transforms chemical energy into … Current research is now trying to identify what proteins are essential for the various reactions that transfer electrons from the bacteria to the anode or take the electrons from the cathode to reduce substrates.

Heavy metals pollution is nowad… Nevertheless, using microbial fuel cells may help reduce environmental contaminants such as wastewater, reduce atmospheric carbon dioxide by using it to rebuild fuels, and may potentially provide a renewable energy source. They work by oxidizing glucose at one electrode (anode) and reducing oxidant at another (cathode). Biofouling 26:57–71. Microbial fuel cell (MFC) is emerging as a modern wastewater treatment technology which converts chemical energy stored in the bonds of organic matter present in wastewater directly into electricity using electrogenic bacteria as a catalyst, without causing environmental pollution. Rev Environ Sci Biotechnol 13:35–51. Int J Mol Sci 16:8266–8293. Electronically functional biomaterials are very attractive because they can be synthesized from relatively inexpensive feedstocks and do not contain toxic components (Hauser and Zhang, 2010). At the cathode, microorganisms can convert the electrons to reduce oxygen to water under aerobic conditions, or convert nitrate to nitrite or N2, or convert CO2 to acetate. ChemSusChem 1:281–282. Most available mediators are expensive and toxic. At the anode compartment, electrons and protons are produced by the oxidation of organic compounds by certain microbes.

Many researchers have started focusing on the ability of microorganisms to produce electric energy in biological systems (Potter, 1910). G. sulfurreducens can also use electrons derived from an electrode to reduce protons to hydrogen (Geelhoed and Stams, 2011), potentially providing a renewable catalyst that is much less expensive than the metal catalysts typically employed for hydrogen production. 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).
