Recent advances in DNA sequencing technology enable us to analyze whole genome and gene expression of organisms comprehensively and rapidly. Our Group is trying to reveal the metabolism, function, and ecology of organisms, and their relationships that are found in tropical & subtropical area using increasing biological information.

We are mainly focusing on the following research subjects.

  1. Symbiotic relationship between marine sponges and their microbial residents that might involve in production of useful bioactive compounds.
  2. Elucidation of migration route, ecology and environmental biofunction of coral-associated microorganisms.
  3. Development of cultivation method for the microbes yet to be cultured by conventional techniques.
  4. Tripartite symbiosis consisting of archaea, bacteria and eukaryote found in anaerobic Trimyema ciliate.
  • A coral reef around Okinawajima Island. Bacteria inhabiting corals or/and coral reef seawater are considered to play important roles in the formation and maintenance of coral reef ecosystem.
