Immobilization of Candida rugosa lipase on magnetic polymer microsphere for synthesis of phytosterol esters of alpha-linolienic acid
摘要
Abstract
Immobilized enzyme of Candida rugosa lipase on magnetic microsphere was used as biocatalyst for synthesis of phytosterol esters of alpha - linolienic. Response surface methodology ( RSM) was employed to evaluate the effects of synthesis conditions. The optimum synthesis conditions were as follows; 25. 2mg/mL immobilized CRL, 146. 5μmol/mL phytosterols concentration, at 55℃ for 5h in the presence of isooctane, the degree of phytos-terols esterification was 92. 61%. By solvent cleaning, the immobilization CRL sustained 78. 1% activities after having been recycled 10 times.关键词
