Immobilization of Pseudomonas cepacia lipase on layered double hydroxide of Zn/Al-Cl for kinetic resolution of rac-1-phenylethanol.
Enzyme and Microbial Technology(2019)
摘要
•Pseudomonas cepacia lipase was immobilized onto Zn/Al-Cl LDH with 96% immobilization efficiency.•Hydrolytic activity in organic medium was 279 U g−1, corresponding to an activity retention of 188%.•In the kinetic resolution of rac-1-phenylethanol, the immobilized lipase gave 50% conversion in 1 h, with E > 200.•Thirty consecutive 1-h cycles of resolution each gave 50% conversion, with E > 200.
