Microbial Diversity and Utilization Research Team

The primary mission of Microbial Diversity and Utilization Research Team (IMUT) is to collect and maintain microorganisms along with relevant information, to serve internal and external researchers. The number of bacteria, yeast and filamentous fungi are more than 80,000 strains. These microbes are a bio-resource for biotechnology research to find valuable products such as enzymes, biological control and bioactive compounds. These microorganisms are available to access for research and commercial use through the Thailand Bioresource Research Center (TBRC) by public and private sector. The study of the diversity and utilization of microbes in agricultural, food-feed, and industrial is another important mission of our research team and the expertise in microbial isolation and identification support the microbial diversity in both species and ecology. The freezing in ultra-low temperature at – 80ºC, freezing in liquid nitrogen vapor and liquid-drying method are used for preserve those microorganisms.
