| Research Abstract |
A microbial community which produced methane under illumination was developed using hot spring microbial mats as a source of microorganisms. In this microbial community, oxygenic photosynthesis by thermophilic cyanobacteria mainly worked as a primary production, heterotrophic bacteria consumed oxygen and degraded organic compounds provided by cyanobacteria, and hydrogen gas produced by fermentation was utilized for methane production by methanogenic archaea. Among these microorganisms, we found several types of interspecies relationship which may help to develop and maintainthe microbial community.
