In Microbial Fuel Cell (MFC) metabolic process within microorganisms helps in the production of voltage due to generation of electrons. When these electrons move across the electrodes they generate a potential difference between electrodes that is the main reason for voltage production. In this study, waste water was used as a nutrient source. A lot of studies are going on the electricity production using organic matter from the wastewater as substrate. Waste biomass is a readily available, cheap source of electrons for microbes that are capable of producing electrical current outside the cell. Waste water was enriched with indigenous microflora of E.coli and E. aerogenes that was cultured in Nutrient broth. The study was conducted with normal MFC, additional carbon source (D-Glucose (0.5%)) and with additional nitrogen source (Ammonium chloride (0.01%)). The maximum voltages obtained after 11 days of culturing were 528mV from normal MFC, 167.4mV from additional carbon source and 308mV with additional nitrogen source. MFC is a new upcoming research area for generation of energy source from waste water. Microbial fuel cells (MFCs) gives a completely new long lasting, affordable, accessible and environment friendly approach to waste water treatment with production of sustainable energy.
