Laboratory for functions of microorganisms
Agriculture Building 403
Yoshida 1677-1
Yamaguchi, 753-8515, JAPAN

Welcome to Laboratory for functions of microorganisms!  » Japanese version

This laboratory is managed by Tomoyuki Kosaka, who belongs to Research Center for Thermotolerant Microbial Resources of Yamaguchi University.

Aiming to elucidate the functions of microorganisms and their utilization,
our research focuses on metabolism as a function. Please see our research projects!

Undergraduate belongs to Faculty of Agriculture, graduate school belongs to Graduate School of Technology for Innovation. We are looking for undergraduate students! Please contact me if you are interested.
