摘要：

Celite-immobilized lipase from Rhizopus arrhizus was encapsulated in lecithin reverse micelles and used to interesterify triacylglycerols of palm oil midfraction with stearic acid in n-hexane. The reaction kinetics were studied in a gas-lift reactor with an internal draft tube. The equilibrium state was reached more rapidly in the gas-lift reactor (9 h) than in comparative shake-flask studies (12 h). A 2.8-fold increase in the productivity of interesterification by Celite-immobilized and lecithin-protected lipase was achieved in the gas-lift reactor when compared with shake-flask experiments. The high productivity of the enzymatic inter esterification was attributed to the combined effects of enzyme immobilization and reactor design.
