Outline of Final Research Achievements

Functions of the uncultured OP5 microorganisms frequently detected in sewage treatment methane fermentation processes were analyzed. The results of spatial distribution of the uncultured OP5 microorganism in sludge granules with fluorescence in situ hybridization and substrate estimation experiment based on rRNA expression, OP5 microorganisms may utilize organic acid (i.e. acetate and propionate) while symbiosis with hydrogen utilizing archaea. The result of attempting to isolate the uncultured OP5 microorganism, the OP5 microorganism and hydrogen utilizing archaea could be enriched with acetate as carbon source.
