| Outline of Final Research Achievements |
Coalbed methane is abundant in coal seams. This study aims to elucidate the unknown biogeochemical cycle of methane in fossil biomass and to develop applied research for future sustainable methane production through an interdisciplinary approach of microbial ecology and geochemistry. Numerous microorganisms were found in subbituminous coal and peat samples collected from several sites in northern Kyushu. These samples showed that the microbial diversity was relatively high and included an uncultivated archaeal lineage, which is likely involved in situ methane production. Evaluation of the methanation potential showed that the microbial metabolism depended on the in vitro pH condition.
