Organization and Activities of RCTMR

 To build up an excellent research center for the utilization of thermotolerant microbes in the fields of fermentation, biomass resourcing, bioremediation, and diagnosis and prevention of infectious diseases, we are trying to establish a novel research and study field with an integrated viewpoint consisting of fermentative, environmental, and pathogenic microbiology, and to undertake pioneering studies and education.

  In this center, we strengthen connections with foreign researchers and research organizations, as well as with many researchers from industrial research institutes, in order to promote international collaboration and also collaboration between academia and the private sector.  Thus, we are actively undertaking research and education with the following staff members and research themes in order to reach our goals.
