Outline of Final Research Achievements

Electromethanogenesis is a bio-electrochemical reaction mediated by a microbially-catalyzed cathode (biocathode), in which carbon dioxide is reduced into methane. This study examined the mechanism of electromethanogenesis catalysed by a high-performance thermophilic biocathode. Metagenome of the catalytic microorganisms was also analysed. Moreover, the first mathematical model of electromethanogenic biocathode was developed.
