• 3-13-2 Microbial community structure in a methane fermentation reactor filled with a carbon fiber carrier

抄録

The purpose of this study was to evaluate the improvement in the efficiency of methane fermentation by filling with a carbon fiber carrier. By this means, accumulation of organic acids such as propionic acid fell and methane production improved. Analysis of the microbial community structure in the reactor, revealed the presence of Anaerobaculum mibile, which participates in organic acid decomposition, and Coprothemobacter proteolyticus, which participates in protein decomposition. Methanothemobacter thermautotrophicus (100% sequence similarity), a hydrogen-assimilating bacterium, was detected. Some studies have found that C. proteolyticus and Methanothermobacter act symbiotically. The adhesion of these microbes to the carbon fiber carrier in the reactor, may have increased the efficiency of methane production.
