| Research Abstract |
Fundamental characteristics of microbial fuel cells (MFCs) equipped with denitrifying biocathodes under anoxic condition were experimentally investigated. The characteristics of cathodic reaction, microbial community in cathodic biofilm, the effects of operational condition and electrode configuration on MFC performance were discussed on the basis of the experimental results obtained. Biological nitrate reduction rate on cathode was rate-limiting step for power generation in the MFC equipped with denitrifying biocathodes. The power generation of MFC using a packed bed of granular graphite as electrodes reached 730mW/m3 with organic matter (acetate) degradation in anode compartment and denitrification in cathode compartment. In cathodic biofilm, autotrophic denitrifying bacteria such as Paracoccus denitrificans were predominantly detected.
