Electricity generation of a sediment type microbial fuel cell set in a paddy field andits effects on the soil environments and methane emission from the paddy field

利用光合微生物产生的氧气提高稻田沉积型微生物燃料电池（SMFC）白天的发电量。这种增强是显着的灌溉期间，其中叶绿素a含量作为光合生物量的指标是高的阴极。利用克隆文库法从阴极中检测到了多种光合微生物。另一方面，从阳极分离到了可能代表新菌种的产电菌株。在SMCF发电增加甲烷排放量从稻田在灌溉期间。

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.
