Microbial fuel cell (MFC) is one of the promising fuel cell technologies.MFCs offer a breakthrough for the treatment of wastewater coupledwith energy generation. However, their applications are mostly limitedto laboratories. Present research is focused on conducting the biologicaltreatment of wastewater originated from fermentation industry usingmicrobial fuel cell (MFC) through the microbes to achieve thewastewater treatment as well as renewable energy generation. Theefficiency of MFC was studied at different operating and nutritionalconditions, including pH, temperature, aeration rate and substrateconcentration with biocatalyst Saccharomyces servisa. The open-circuitmaximum voltage generated 2100 mv and using 50 Ω resister given 1800mv. Numerous parametric effect was measured by altering the value ofaeration rate from 20-35 mL/min with 5 mL/min step size; pH from 6-9with step size pH 1, and substrate from 25-100% with step size 25%.From above discussed parameter power and current density weremaximum at pH 8 about 725 mv/l and 350 mA. Results suggested thatutilization of fermented sludge in MFC could give direction to handle theproblem of fermentation industries and also to overcome a smallfraction of energy crisis.Keywords: Electricity generation, Primary fermented sludge, Microbialfuel cell
