Associate Professor / KASAI Daisuke
The assoc. prof. KASAI is emerging and very dedicated researcher. He explains and advises our questions carefully one by one. He also sometimes helps us by conducting experiments himself. Shall you try with him to discover new advances in environmental microbiology?

Research Content

We are mainly researching on "rubber-utilizing bacteria" and "biodegradable plastic-biosynthetic bacteria" to solve the problems related to waste rubber and petroleum plastics, which are one of the causes of environmental pollution. These research include the creation of artificial mutations using PCR, cloning, and genetic recombination, and the analysis of degradants and biosynthetic substances using gas chromatography (GC) and gel permeation chromatography (GPC). Our goal is that the results of our research will contribute to the maintenance of the global environment, which faces a variety of problems.

Inside our laboratory

A Day in the Lab

Our lab day starts at 10:30 a.m. and ends at 3:30 p.m. Each experiment can be performed freely during the allotted time, and if there is extra time, students can help with other experiments or search for papers related to their research. The results of each experiment are presented in a group discussion, and with the advice of Dr. Kasai and senior students, the students move on to the next step. If you are interested in microorganisms and experiments with them, join us.
