Biomethane production from sugar beet pulp under cocultivation with Clostridium cellulovorans and methanogens.

ABSTRACT: This study was demonstrated with a coculture fermentation system using sugar beet pulp (SBP) as a carbon source combining the cellulose-degrading bacterium Clostridium cellulovorans with microbial flora of methane production (MFMP) for the direct conversion of cellulosic biomass to methane (CH₄). The MFMP was taken from a commercial methane fermentation plant and extremely complicated. Therefore, the MFMP was analyzed by a next-generation sequencing system and the microbiome was identified and classified based on several computer programs. As a result, Methanosarcina mazei (1.34% of total counts) and the other methanogens were found in the MFMP. Interestingly, the simultaneous utilization of hydrogen (H₂) and carbon dioxide (CO₂) for methanogenesis was obse
