Research Abstract

Electricity output during the daytime in a sediment type microbial fuell cell (SMFC) set in a paddy field was enhanced by oxygen produced by photosynthetic microorganisms. This enhancement was significant during the irrigation period, in which chlorophyll a content as an indicator of photosynthetic biomass was high on the cathode. Diverse photosynthetic microorganisms were detected from the cathode by using clone library method. On the other hand, from anode, the exoelectrogenic strains which might represent new species of bacteria were successfully isolated. Electricity generation in the SMCF increased methane emission from the paddy field during the irrigation period.
