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.
