| Outline of Final Research Achievements |
To develop a high-throughput microbial separation and cultivation method for unculturable microorganisms, a liquid cultivation method using 96-well microplates was applied for anaerobic microorganisms in a methane fermentation process. Aceticlastic methanogens affiliated with the genera Methanosaeta and Methanosarcina, as well as hydrogenotrophic methanogen affiliated with the genus Methanolinea, were separately cultivated on a medium with acetate as the sole carbon source. Acetate-oxidizing bacteria, which could form syntrophic associations with hydrogenotrophic methnaogens, could not be identified. This study would provide a novel culture-dependent method for analysis on the taxonomic diversity and physiological functions of anaerobic acetate-oxidizing syntrophs with hydrogenotrophic methanogens, which play important roles for acetate conversion to methane in methane fermentation processes.
