Laboratory of Resource Circulation Bioengineering studies environmental biotechnology, which utilizes the microorganisms to convert waste biomass into useful resources. We use two approaches, microbial engineering and bioinformatics, to achieve the high efficiency and to elucidate the mechanisms. Our goal is to make environmental biotechnology faster, more economical, smaller, and easier to use, which would contribute to the development of a biomass-recycling society.
