Microbial Fuel Cells (MFCs) use bacteria as biocatalyst to convert biodegradable substrates into electricity. The normal sea water generated maximum Open Circuit Voltage (OCV) of 4.5mV while sterile sea water generated only 0.9mV OCV in the H-shaped MFC. On optimization of MFC setup, 100% sea water and a salt bridge (5cm __ampersandsigntimes; 2cm) containing a mixture of 10% sodium chloride and 5% agar, and electrodes of 32.20cm2 surface area was found ideal. Furthermore, two electrogenic bacteria were isolated from the sea water and individually studied for their electrogenicity. The isolate SWA1 was selected as electrogenic bacteria, as it generated 754.7mV OCV at 37__ampersandsignordm;C, pH 7.0 with LB medium as anolyte against vinegar as catholyte after 24h inoculation in MFC. Based on phenotypic characteristics and 16S rDNA sequencing, isolate SWA1 was identified as Pseudoalteromonas sp.
