Bioelectrochemical Behavior Of Wild Type Bacillus Cereus In Dual Chamber Microbial Fuel Cell

Bioelectrochemical Behavior Of Wild Type Bacillus Cereus In Dual Chamber Microbial Fuel Cell

A microbial fuel cell (MFC) is a bioelectrochemical system that uses living microbes as biocatalyst to oxidize organic substrates as well as release electrons that can be harvested in an external circuit to produce electrical energy. In this study, a proteolytic biocatalyst, Bacillus cereus, has bee...
