“…Several yeast strains have been studied as biocatalysts in MFC with or without external mediator such as Saccharomyces cerevisiae (S. cerevisiae) [41][42][43][44][45][46][47][48][49][50][51][52], Candida melibiosica 2491 (C. melibiosica) [53][54][55][56], Hansenula anomala (H. anomala) [40], Hansenula polymorpha (Hansenula polymorpha) [57], Arxula adeninivorans (A. adeninivorans) [58] and Kluyveromyces marxianus (K. marxianus) [59].…”

“…The effect of the mediator type, i.e., bromocresol green (BcG), bromocresol purple, romothymol blue, bromophenol blue, Congo red, cresol red, eosin, eriochrome black T, methyl red, methanyl yellow, MB, methyl orange, murexide and NR on the performance of C. melibiosicabased MFC was investigated [54]. Results showed that among the investigated mediators, MB, methyl orange, methyl red and NR increased the performance compared to the mediatorless MFC.…”

“…Methylene Blue has also been used as an electron mediator to increase power production in MFC (Zuo et al 2007). Babanova et al (2011) reported the order of mediators as Bromocresol Blue < Neutral Red < Methyl Red < Methyl Orange < Methylene Blue in terms of power generation in MFC.…”

“…The electrons generated by the bacteria upon substrate utilization anaerobically are transferred to the anode either by an exogenous electron carrier compound (potassium ferricyanide, thionine, neutral red, methylene blue Park & Zeikus 2000;Rabaey, Boon, Dendf et al 2004, Rabaey, Boon, Siciliano et al 2004Zhou et al 2007;Babanova et al 2011) or directly from the enzyme involved in bacterial respiration to the electrode or with or without (Bond and Lovley 2003;Chaudhuri and Lovely 2003;Gil et al 2003) the help of mediators. Exogenous chemical compounds used as mediators in MFC have certain demerits such as toxicity and their expensive nature (Bond & Lovley 2003;Gil et al 2003).…”

Bioelectricity production involves generation of electricity by anaerobic digestion of organic substrates by microbes. A microbial fuel cell (MFC) is a device that converts chemical energy released as a result of oxidation of complex organic carbon sources which are utilized as substrates by microorganisms to produce electrical energy thereby proving to be an efficient means of sustainable energy production. The electrons released due to the microbial metabolism are captured to maintain a constant power density, without an effective carbon emission in the ecosystem. The various parameters involved in MFC technology toward power generation include maximum power density, coulombic efficiencies and sometimes chemical oxygen demand removal rate which evaluates the effectiveness of the device. Application of microbes toward bioremediation at the same time resulting in generation of electricity makes MFC technology a highly advantageous proposition which can be applied in various sectors of industrial, municipal and agricultural Waste Management. Although the efficiency of MFCs in power generation initially was low, recent modifications in the design, components and working have enhanced the power output to a significant level thereby enabling application of MFCs in various fields including wastewater treatment, biosensors and bioremediation. The following review provides an outline about the components involved, working, modifications and applications of MFC technology for various research and industrial objectives. ARTICLE HISTORY

“…Microbial fuel cell (MFC) is bio-electrochemical devices that use microbe as catalyst to convert organic and inorganic substrates into electrical current (Hubenova and Mitov, 2015;Prasad et al, 2007;Min and Logan, 2004;Babanova et al, 2011). The core principle of MFC is the metabolism process of microbe which consist of two steps.…”

Microbial fuel Cell (MFC) has gained a lot of attention in recent years due to its capability in simultaneously reducing organic component and generating electricity. Here multicultural rumen microbes (RM) were used to reduce organic component of slaughterhouse wastewater in a self-fabricated MFC. The objectives of this study were to determine the MFC configuration and to find out its maximum capability in organic degradation and electricity generation. The experiments were conducted by employing, different types of electrode materials, electrode size, and substrate-RM ratio. Configuration of MFC with graphite-copper electrode 31.4 cm2 in size, and substrate-RM ratio 1:10 shows the best result with current density of 318 mA m-2, potential 2.4 V, and achieve maximum power density up to 700 mW m-2. In addition, self-fabricated MFC also shows its ability in reducing organic component by measuring the chemical oxygen demand (COD) up to 67.9% followed by increasing pH from 5.9 to 7.5. MFC operating at ambient condition (29oC and pH 7.5), is emphasized as green-technology for slaughterhouse wastewater treatment.
