Microbial fuel cells


​​  


Published on 8 July 2015

​The capability of microorganisms to exchange electrons with solid substrates has, particularly in the last decade, led to a new technology field: microbial electrochemistry and consequently to bioenergy production.

Microbial fuel cells (MFCs) are devices, which directly convert, through microbial action, the chemical energy stored in organic matter, into electrical energy. These rely on electroactive bacteria (EAB) to transfer electrons through a series of electron-carrier proteins, through the anode, via an external load, through a fuel cell cathode to a terminal electron acceptor, usually oxygen.

We aim at a better understanding of the physiology and ecology of EAB in order to discern the molecular mechanisms that mediate microbial bioenergy production, and optimize existing microbial bioenergy systems.
