Research interest:

 Because of homo-chirality in biology on the earth, which means amino acids, for example, are composed of only left-handed or L-isomer, the discovery and development of stereoselective organic synthetic methods for pharmaceutical and agrochemicals are very important. Chemical and biological catalysts have been developed throughout several decades. To synthesize them in environmentally friendly methods, we have been using enzymes as catalysts. Particularly, we have found that strains of Geotrichum candidum have many robust oxidoreductases with extremely excellent stereoselectivity. Moreover, we succeeded in reactions by the microorganisms in non-aqueous green solvents such as supercritical CO2.

 We also achieved the waste-minimization in large-scale production of chiral compounds with a flow system using liquid CO2 as a solvent and an immobilized lipase as a catalyst packed in a column reactor. Moreover, lipase catalyzed reactions were found to be effectively enhanced using a liquid CO2 medium when they were compared with those using organic solvents. Now, we are pursuing to elucidate the mechanism of the acceleration in enzymatic reactions caused by CO2. By these studies of green chemistry using enzyme and CO2, we hope to fulfill the role of scientist to protect environments for the bright future.
