Microbial Fuel Cell (MFC) technology is an efficient technology which has a practical aspect of conversion of chemical energy in organic compounds directly to electrical energy through degradative activities of microorganisms. MFCs can be used in wastewater treatment plants with simultaneous generation of electricity. A lot of research has already been done and different types of MFCs have been constructed which have varied applications in addition to electricity generation. This article presents a short review on MFCs stating its working, types and applications with broader view on wastewater treatment.
ELECTRICITY PRODUCTION FROM WASTE WATER BY MICROBIAL FUEL CELL
A microbial fuel cell (MFC) is a bio-electrochemical system that converts the chemical energy in the organic compounds such as acetate, lactate, and glucose. It converts renewable energy sources to electrical energy under anaerobic conditions. So it is possible to produce electricity in a MFC from wastewaters. This process is an alternative methodology for generation of electricity. Here the MFC used three different wastewater samples which were achieved maximum power with Tannery effluent was obtained 414 mV followed by municipal wastewater 254 mV and domestic waste water 244 mV. It has been found that a mixture of cow dung can actually result in higher voltage than lechate and kitchen waste. MFC also used to treat the wastewaters under anaerobic process. The highest efficiency of DO removal has been achieved by Tannery waste water (57.14 %), followed by municipal wastewater (50 %) and pond water (44.4%). The Tannery effluent shows the highest efficiency for TSS (55.4 %), followed by municipal waste water (51.64 %) and pond water (46.98 %).

The performance of electricity producing of Dual Chamber Microbial Fuel Cells (MFCs) using wastewater of tempe industries without glucose addition (as control substrate) and with (2% and 4%) glucose addition was observed. The anode chamber contained a waste substrate and a cathode chamber contained a 0.1 M Potassium Permanganate electrolyte solution. The salt bridge was required to stabilize the charge between the cathode and anode chambers, and the electrodes attached to the anode and cathode chambers as the electron catcher. Voltages and currents were measured using multimeter. Optical Density measured at 486 nm wavelengths was performed to estimate bacterial growth activity. All of the cells were observed for 72 hours of running time. The results of Optical Density curves showed an increasing trend of absorbance during 72 hours of running time. These were in agreement with the resulting power density, which tended to increase until the 48th hour and then relatively stable especia...
PERFORMANCE STUDIES OF MICROBIAL FUEL CELL
Microbial fuel cells (MFCs) have gained a lot of attention in recent years for its ability to convert organic matter into electricity in the presence of microbes. Lot of research has been carried out on using wide range of substrates like acetate, glucose, monosaccharaides, domestic wastewater, industrial wastewater etc. Phenol and detergent are the major toxic components from industrial and domestic wastewater. If it is left untreated it can have detrimental effect on all kinds of aquatic life. In industries there are methods available for the treatment of these contaminants; however research on use of MFCs for treatment of these contaminants is still in infant stage. Using MFC will have a dual advantage of wastewater treatment as well as electricity generation. In this study a dual-chamber MFC was fabricated with a CMI 7000 membrane separating the chambers and carbon electrodes for both anode and cathode. Experiments were carried out to study the impact of microbes, type of substrate, substrate concentration and substrate refilling at regular intervals on voltage generated by MFC. Performance of MFC was studied by determining the voltage across 1kΩ resistor. Furthermore, Industrial waste water from a local soap industry was used as a substrate along with the other substrates prepared in-house. Results showed that a stable voltage of around 134mV can be obtained with phenol as substrate along with a mixed culture of pseudomonas aeruginosa and shewanella putrefaciens in comparison with all other combinations of substrates and microbes.

The growing concern of environmental pollution due to the excessive exploitation of fossil fuel has shifted attention to a more renewable source of procuring energy one of them being the microbial fuel cells. The development of MFC is essentially based on the potential of bacteria to generate electrons by metabolizing the substrate (sewage wastewater, here). The mechanism of working of microbial fuel cells is mentioned. The use of sewage wastewater to tap electricity while simultaneously decreasing the COD (Chemical Oxygen Demand) level in the water for it's safe disposal with efficient materials for the PEM (Proton Exchange Membrane), cathode, mediators etc. have been reviewed. The best mode of operation of MFC to generate maximum power density in both single and double chambered MFC has been explored.
MICROBIAL FUEL CELL FOR ELECTRICITY PRODUCTION
In this research paper I have tried to build the microbial fuel cell using the kitchen waste water like the rice washed water and other household waste as the biomass using the E.coli and C.sporengenes species and tried to measure their potential to produce the electricity. I also have compared the results of the potential of both the species in production of electric current using different biomass for various incubation time periods. Initially the species were inoculated in their growth media for 24hours to grow at sufficient quantity. Later on I built the MFC using 2 PAC bottles using the agar-salt bridge. Then I inoculated the species with different biomass separately in separate MFC set up. Further I allowed the species to respire anaerobically and completed the circuit with external connections. I also connected a multimeter and thus after the incubation the bacterias fed on the biomass and converted the organic matter to electricity which was measured and tabulated graphically. Thus the bacterial potential of electricity production was made practical and their properties were explored.

Bioelectricity is the electric current produced by anaerobic ingestion of organic substrate by microorganism. A microbial fuel cell (MFC) is a appliance that transforms energy discharged outcome of oxidation of complicated natural carbon sources that area unit used as substrates by microorganisms to provide voltage thus demonstrating to be associate proficient ways that of viable energy production. The electrons released because of the microbial breakdown is seized to keep up ruthless potential density while not an efficient carbon discharge within system. Usage of microorganisms toward bioremediation is similar to the consequence as of the generation of electricity creates the MFC technology a very beneficial plan which could be smeared in varied segment of industries and agricultural wastes. Although the influences of MFCs in generation of electricity was initially low, modern development within the style elements and dealing has increased ability yield to a major step thus permit application of MFCs in varied sectors as well as waste material ministrations and biodepollution. The accompanying review gives a top-level view concerning the parts, operating, alteration and purpose of MFC technology for numerous analysis and industrial application.

In the present investigation, power generation in MFC containing salt bridge as a proton exchange material using mixed microbial culture from the dairy waste treatment plant (anaerobic digester) wasstudied. Power output by the MFC with mixed culture was 2.8 mW/m 2 . The synthetic medium decomposes with fermentative process by mixed microbial culture producing hydrogen as the fuel for fuel cell. The electricity produced with microbial fuel cell was studied with different parameters like open circuit voltage, the current flowing through the external circuit and the variation of power output with the load resistance. The exploitation of mesophilic, chemotrophic bacteria allows a flexible access to different substrates including complex carbohydrates. The performance of microbial fuel cell over the period of fermentative utilization of the synthetic media wasinvestigated and the role of microbes in the electricity generation of microbial fuel cellsis reported in the paper.
