Effect of immobilization support, water activity, and enzyme ionization state on cutinase activity and enantioselectivity in organic media
We studied the reaction between vinyl butyrate and 2‐phenyl‐1‐propanol in acetonitrile catalyzed by Fusarium solani pisi cutinase immobilized on zeolites NaA and NaY and on Accurel PA‐6. The choice… Expand
