Effect of organic solvents on enzymatic production of cyclodextrins from unliquefied corn starch in an attrition bioreactor
1992
Lee, Y.D. | Kim, H.S.
Cyclodextrins were produced from unliquefied corn starch in the presence of water-miscible organic solvents using cyclodextrin glycosyltransferase (CGTase) in an attrition bioreactor. The production yield was significantly increased by isopropanol and tertiary butanol, and maximum enhancement was observed to be about 40% by 5% tertiary butanol. Increase in the production of cyclodextrins by organic solvents seems to be due to the fact that organic solvents decreased the product inhibition of CGTase by forming an inclusion complex with cyclodextrins.
