Microbial fuel cell (MFC) has become a great attraction amongst most researchers, where degradation of waste takes place simultaneously produces electricity. Using an efficient organism and a better proton exchange membrane gives out good electricity. In this study, Exiguobacterium sp SU-5 was isolated from soil and used for producing electricity against carboxy methyl cellulose (CMC) in Nafion membrane and Salt bridge fitted MFC, where both act as proton exchange membrane. The organism was found to produce more electricity in Nafion membrane fitted MFC. Later the organism was subjected to produce electricity against kitchen waste and the kitchen waste was also checked for BOD, COD and other water analysis before and after the treatment. The organism could produce more electricity in Nafion membrane fitted MFC and found to reduce chloride, fluoride and hardness of water.
