The study of electrochemically active planktonic microbes in microbial fuel cells in relation to different carbon-based anode materials

Abstract

Abstract MFCs (Microbial fuel cells) are bio-electrochemical systems that convert chemical energy into electrical energy by utilizing electrochemically active bacteria. rt-qPCR (Real-time quantitative polymerase chain reaction) assays were used to identify the planktonic bacteria present in the production of electricity in MFCs. The relationship between the bacterial communities with different carbon-based anode materials, such as C-FELT (carbon felt), carbon felt with C-PANI (polyaniline) and C-SADDLES (carbon-coated Berl saddles), were investigated. The distribution of bacteria among the three different MFC anode materials was evaluated. Significant differences were observed for total bacteria (p Geobacter (p Shewanella (p 3 when compared with the C-FELT (4.7 W/m 3 ) and C-SADDLES (4.6 W/m 3 ) MFCs. The greatest number of electrochemically active planktonic microbes was observed in the C-FELT MFC, whereas the C-PANI MFC had the optimum carbon-based anode material.
