Abstract
Microbial Fuel Cells (MFC) are bioreactors that convert chemical energy in the bonds of organic matters into alcohol &electricity through bio-catalysis of microorganisms. To provide new opportunities for the sustainable production of energy from biodegradable compounds from different substrates MFC is introduced. The MFC was built with graphite and copper electrodes with agarose as salt bridge using a sustainable raw material like sludge and sewage. The study focused on design, optimization and analysis of electricity generation and alcohol production through various substrates and time duration. The biofilm formation which is the main indication for the electricity production was estimated from the isolated microorganisms using specific tests such as turbidity analysis, EPS analysis and crystal violet test. The biofilm formation supports the electricity generation capacity. In conclusion, Sewage was best among vegetable waste, fruit waste and rice water. And sewage biomass has showed higher electricity generation and alcohol production, which was tested and proven to be methanol.
