Abstract
Microbial fuel cells (MFCs) are the electrochemical systems that harness electron from the reduction of organic compounds using microbes as a catalyst. 3 combinations from 4 electrodes that are, Zn (14.9cm×4.9cm), Carbon (14cm×1.5cm), Cu (14.9cm×4.9cm) and Al (14cm×4.5cm) were assessed . Zn-C, as an anode-cathode combination produced maximum voltage of 1.1±0.03V and current 1.5±0.12mA. In present study,gram negative non-fermentative staphylococcus bacterium was isolated from a mediator-less microbial fuel cell, fed with rice bran oil refinery wastewater operated in fed-batch manner. The isolate produced potential of 1.01±0.01V and current of 1.24±0.03mA using synthetic wastewater. The newly isolated bacterium has potential of generating electricity in MFC system and may hold many possibilities with different wastewater as well as in practical applications.
