| Outline of Final Research Achievements |
Our research focused on microbial communities in terrestrial deep subsurface environments to reveal the entity of microbes responsible for methanogenesis from subsurface organic compounds. By taking advantage of newly developed high pressure cultivation apparatus, we were successful in isolation of novel archaea, bacteria, and their highly enriched cultures that greatly contribute to the conversion of organic compounds such as hydrocarbons and methoxylated aromatic compounds into methane. We also obtained new insights into the origin of methane based on stable isotope fractionations with highly elaborate culture-based experiments.
