Microbial fuel cells used in the production of electricity from organic waste: A perspective of future

Abstract

In this review is presented an innovative technology for use of animal and vegetable waste with high pollution levels in microbial fuel cell (MFC) as an alternative to waste remediation and simultaneously producing electricity and fertilizer for agriculture. A brief history of MFC, the studies about the electron transfer mechanisms, discussion of the biological nanowires in bacteria and the use of chemical mediators or carriers of electrons are explained. The factors infuencing the performance of MFCs, the application in waste and sewage treatment and power generation are also discussed.
