Abstract

Genipin, a natural cross-linking agent, was used for the immobilization of lipase from Candida sp. 99-125 by cross-linking to two kinds of mesoporous resins. Under optimum conditions, the activity recovery of immobilized lipase on resin NKA-9 could reach up to 96.99% when the genipin concentration was 0.5%, and it could reach up to 86.18% for S-8 with a genipin concentration of 0.25%. Compared with using glutaraldehyde as a cross-linking agent, the immobilized lipase using genipin showed better pH and thermal stability, storage stability, and reusability. The residual activity of immobilized lipase using genipin as cross-linker remained more than 60% of its initial activity after six hydrolytic cycles, whereas only about 35% activity remained by using glutaraldehyde as cross-linker.
