“…The relative abundance in two phyla: Proteobacteria and Actinobacteria remained at comparable levels in the inoculum and operation of the MFC. The presence of these two phyla was also observed in a two-chamber MFC fed cow manure [34]. that typically produced with acetate, but more similar to previous results when using insoluble cellulose as a substrate [5].…”

Abstract:The abundance of cellulosic wastes make them attractive source of energy for producing electricity in microbial fuel cells (MFCs). However, electricity production from cellulose requires obligate anaerobes that can degrade cellulose and transfer electrons to the electrode (exoelectrogens), and thus most previous MFC studies have been conducted using two-chamber systems to avoid oxygen contamination of the anode. Single-chamber, air-cathode MFCs typically produce higher power densities than aqueous catholyte MFCs and avoid energy input for the cathodic reaction. To better understand the bacterial communities that evolve in single-chamber air-cathode MFCs fed cellulose, we examined the changes in the bacterial consortium in an MFC fed cellulose over time. The most predominant bacteria shown to be capable electron generation was Firmicutes, with the fermenters decomposing cellulose Bacteroidetes. The main genera developed after extended operation of the cellulose-fed MFC were cellulolytic strains, fermenters and electrogens that included: Parabacteroides, Proteiniphilum, Catonella and Clostridium. These results demonstrate that different communities evolve in air-cathode MFCs fed cellulose than the previous two-chamber reactors.

Anaerobic acidogenesis of cattle dung revealed Clostridium sp., Pseudomonas luteola and Ochrobactrum pseudogrignonense to be the most dominant groups present responsible for the electricity generation process (Zhao et al 2012).

“…Thus, inclusion of these waste products as substrates in MFC technology makes it a more potent means of sustainable energy generation. Industrial and domestic wastewaters namely sewage, cattle, swine and brewery wastewaters have been employed as potential substrates in MFC technology generating efficient results (Min et al 2005;Feng et al 2008;Zhao et al 2012). Upgrading these models to a larger scale would aim to decrease the energy expenditure in terms of their treatment .…”

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

“…The microbial fuel cell is a device which generates electricity by the metabolic activities of the microbes. Microorganisms transfer the electrons obtained from the metabolism of organic matters in the anode and thereby to the cathode through an external circuit, hence generate electricity [1,2] .Though a century old technique, which was initially recognized for treatment of wastewater, MFC is gaining its interest for the generation of electricity, bio-hydrogen and also used as biosensor [3,4]. Any biodegradable organic matter ranging from pure compounds such as glycerol, acetate, starch, glucose, cysteine, and ethanol [3,5] to complex mixtures of organic matter such as wastewater [6], cow dung [2], kitchen waste [6] and ionic strength.…”

Abstract.A microbial fuel cell (MFC) consists of a cathode and anode; micro-organisms transfer electrons acquired from the degradation of organic matter in the substrate to anode; and thereby to cathode; by using an external circuit to generate electricity. In the present study, a single chamber single electrode microbial fuel cell has been fabricated to generate electricity from the sludge of the sewage treatment plant at two different ambient temperature range of 25 ± 4°C and 32 ± 4°C under aerobic condition. No work has been done yet by using the single electrode in any MFC system; it is hypothesized that single electrode submerged partially in substrate and rest to atmosphere can function as both cathode and anode. The maximum voltage obtained was about 2890 mV after 80 (hrs) at temperature range of 25 ± 4°C, with surface power density of 1108.29 mW/m 2 . When the ambient temperature was 32 ± 4°C, maximum voltage obtained was 1652 mV after 40 (hrs.) surface power density reduced to 865.57 mW/m 2 . When amount of substrate was decreased for certain area of electrode at 25 ± 4°C range, electricity generation decreased and it also shortened the time to reach peak voltage. On the other hand, when the ambient temperature was increased to 32 ± 4°C, the maximum potential energy generated was less than that of previous experiment at 25 ± 4°C for the same substrate Also the time to reach peak voltage decreased to 40 hrs. When comparing with other single chamber single electrode MFC, the present model is generating more electricity that any MFC using sewage sludge as substrate except platinum electrode, which is much costlier that electrode used in the present study.
