Abstract


Diminishing natural resources and increasing electricity requirement for world population necessitates the development of new technologies that can provide alternatives to traditional energy sources in sustainable way. Microbial fuel cell (MFC) has emerged as a promising technology to counteract the prosperous global energy demands of future. With the prospect of greater environmental protection and energy recovery, MFC produce electrical energy through catalytic reactions of microorganisms under anaerobic conditions. It involves the microbe assisted biochemical reactions inducing transference directly. Organic matter is used as a fuel in wastewater to remove the contaminants and produce electricity. The feasibility of this process as a source of “green electricity” has been proven for industrial and domestic waste. MFCs have great potential for sustainable waste treatment and energy production through the linkage to sources of agricultural, animal or municipal waste. This review provides a critical insight into recent developments in microbial fuel cells technology and their possible applications
