기질에 따른 미생물 전해 전지-혐기성 소화의 미생물 군집 특성 = Effect of Substrates on the Microbial Communities in a Microbial Electrolysis Cell and Anaerobic Digestion Coupled System

다국어 초록 (Multilingual Abstract)

This study was conducted to evaluate the microbial communities in coupled system of a microbial electrolysis cell and an anaerobic digestion. Glucose, butyric acid, propionic acid and acetic acid were used as substrates. The maximum methane production and methane production rate of propionic acid respectively were 327.9±6.7 mL CH4/g COD and 28.3±3.1 mL CH4/g COD·d, which were higher than others. Microbial communities’ analyses indicated that acetoclastic methangens were predominant in all systems. But the proportion of hydrogenotrophic methanogens was higher in the system using propionic acid as a substrate when compared to others. In coupled system of a microbial electrolysis cell and anaerobic digestion, the methane production was higher as the distribution of hydrogen, which was generated by substrate degradation, and proportion of hydrogenotrophic methanogens was higher.
