Anaerobic digestion has been reportedly utilized to reduce organic contaminants and recover renewable energy (i.e. bio gas). Biogas is a renewable energy carrier gas consisting mainly of methane (CH4, 40−75%) and carbon dioxide (CO2, 15−60%), which was converted by acetotrophic and hydrogenotrophic methanogens during anaerobic conversion of particulate biomass to methane. Recently, the bioelectrochemical system (BES) based CO2 conversion provide a potential route to improve conversion efficiency and cell growth of strains for methane and/or value-added platform chemicals. In this study, we investigated the syntrophic electromethanogensis for methane conversion from CO2 gas based on the bioelectrochemical system in order to optimized control. As results, we obtained highly methane conversion rate and coulombic efficiency. |
