Mikrobiyal Yakıt Hücrelerinde Ekstraselüler Elektron Transferleri

Abstract

Recently, the increase in the use of fossil fuels triggers a global energy crisis. Renewable bioenergy is viewed as one of the ways to alleviate
the energy crisis. Microbial fuel cells (MFC) systems that use bacteria converting biochemical energy in organic compounds to electrical energy
have a great interest among academic researchers nowadays. In spite of the fact that most of researchers have focused on MFC architecture to
optimize power output, the actual microbiological processes taking place in the microbial fuel cells are not well defined. In MFC systems, one of
the most important parameters affecting power generation is the mediators that enhance the transport of generated electrons from bacteria degrading
organic matters to the anode which is a component of MFC system. In this article, the investigated studies about mechanisms of electron transfer
and importance of mediators in MFC systems are reviewed.
