Microbial fuel cells using exoelectrogens such as Shewanella oneidensis and Geobacter sulfureduccuns are already reported in many articles. Klebsiella pneumoniae was also reported as exoelectrogen. 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. |
