- To aim at comprehensively understanding metabolic potential of the microbial community occurring in the deep-sea and deep subsurface environments based on the metagenomic information and various environmental factors.
- To aim at clarifying the metabolic potential and evolutionary position of uncultivable microbes by reconstruction of their genomes from the metagenomic libraries.
- To aim for industrial application by exploring the useful enzymes using the metagenomic libraries prepared from various unique environments.
As mentioned above, our environmental metagenome research team began metagenomic project to figure out prokaryotic life style in the deep-sea and deep subsurface environments. We focused on the microbial mat occurring along with a hot water stream in the Japanese epithermal mine as the first target site for metagenomics. As the nest target, we also focused on ocean drilling core samples offshore the Shinmokita Peninsula, Japan and the deep-sea mud in the Marina Trench at a depth of 11,000 m and have been proceeding with metagenomic analysis since 2007 to figure out the microbial ecosystems and their movement.
