Optimization And Energy Production By Microbial Fuel Cell

Microbial fuel cell (MFC) involves the bioelectrochemical reaction which produces electricity by the microorganisms. MFC converts the biochemical metabolic energy to electrical energy through microbial catalyst at the anode under anaerobic conditions. It is the apt answer of alternative energy source in recent increasing energy crisis. In microbial fuel cells, bacteria generate electricity by mediating the oxidation of organic compounds and transferring the resulting electrons to an anode electrode. The power output depends on the types of microbes used in anodic chamber, configuration of MFC and operating conditions. In the present work, different microbial cultures were isolated and screened from waste water sample. The bacterial isolates, Enterobacter sp., Staphylococcus sp. and Pseudomonas sp. showed maximum power density. The voltage was measured and compared among all the microorganisms. For the efficient energy generation, the biological optimization also was done.
