Treatment of Oil refinery waste water simultaneously with Bioelectricity production in Mediator-less Microbial Fuel cell using native Gram positive Bacillus sp.

Abstract

Microbial fuel cells standalone effective approach for generating electricity directly from the breakdown of waste organic matter or almost any renewable biomass using diverse metabolic activity of native electrogenic microorganisms. This communication reports effect of various factors on electricity production and efficient treatment of rice bran oil refinery wastewater used as fuel in mediator-less Microbial fuel cells (MFCs). The work represents efficacy of low-cost, simple and easy-to operate microbial fuel cells assisted with isolate WRS-6 for generating electricity to glow LED of 4V using oil refinery wastewater alone; and with combination of starch from cooked rice, sap of rotten fruit, vegetable waste from kitchen for about 10 days.
