Outline of Final Research Achievements

Metagenomic analysis of a methanogenic microbial community in an anaerobic bioreactor treating amino acid-containing wastewater revealed synergistic metabolic network of syntrophic substrate-oxidizing bacteria, methanogens, and functionally unknown microorganisms. A laboratory-scale upflow anaerobic sludge blanket reactor fed with wastewater discharged from soy sauce processing manufactory was operated at 20°C. We successfully recovered metagenomic bins of dominant microbes in the reactor. Metabolic reconstruction suggested that dominant microorganisms perform fermentative and syntrophic degradation of amino acids and catabolic by-products facilitated by various energy conservation systems. Thus, diverse anaerobic organisms may unite to form a metabolic network to perform complete degradation of amino acids in the methanogenic microbiota.
