| Summary: | The microorganisms such as bacteria act as
biological catalysts in microbial fuel cells (MFCs). These
microorganisms oxidize the organic matter at the anode
and transfer the electrons exogenously to the electrode
surface (anode surface) without any need of artificial
mediators. Such microorganisms have been referred as
exoelectrogens. They form conductive biofilms on the
electrode surface, metabolize the substrates into electrons,
protons and carbon dioxide. The exoelectrogens produce
some redox proteins such as c-type cytochromes and pili
for direct electron transfer, and some electron shuttles e.g.,
pyocyanin for mediated electron transfer. |
