Bioelectricity is highlighted as an alternative for fossil fuel energy. Microbial fuel cells (MFCs) are a bioelectricity generation system using exoelectrogens as a catalyst. Klebsiella pneumoniae was reported as one of the exoelectrogen excreting mediator for electron transfer. In this study, K. pneumoniae J2B was employed into H-type MFC for electrogenesis with glucose as electron donor. The potential was measured as 4.8 ± 0.9 mV at a resistance of 2,000 Ω and current at 2.4 ± 0.8 μA after 6 hour inoculation. The polarization curves might present that K. pneumoniae J2B strain produced mediators for extracellular electron transfer. Although this system produced low electricity, K. pneumoniae J2B strain seems to be potential exoelectrogen for generating electricity from glucose in MFC system; it can be applied in industrial fermentation through the change the intracellular redox potential. |
