Abstract

Microbial fuel cells (MFCs) are new bioprocess method for conversion of chemical
energy in organic matters to bioelectricity. In some MFCs produced electrons can travels
to anode surface directly and need some artificial component to transfer the produced
electron to anode surface. This paper tries to highlight different mediators that have been
used as electron mediators in the MFCs in recent years. In this research study, Escherichia
coli ATCC 8739 was used for power production in an anaerobic condition. Methylene
blue, thionine, humic acid, potassium fericyanide and neutral red at different
concentrations (50 to 500μmoll-1) are selected and analyzed with several concentrations as
mediators. Cyclic voltammetry use to study of anodic electrochemistry analysis. All
experiment carry out in aerobic an anaerobic condition but at aerobic condition did not
obtain significance peak. The obtained results demonstrate that NR has better ability for
transfer of electron in this study.
