Immobilization of Lipase on MCM-41 Nanospheres: Exploring the Effects of Supports Morphology on the Lipase Immobilization

Abstract:

In this study, the effects of the supports morphology on the lipase immobilization were discussed. PVA-MCM-41 with perfect spherical morphology, which was synthesized in the presence of PVA, was introduced to compare with MCM-41 which is irregular in shape and aggregate seriously. The amount of lipase immobilized on PVA-MCM-41 was a little higher than that immobilized on MCM-41. However, the activity of the former is just around 50% of the latter. The lipase immobilized on PVA-MCM-41 exhibited well reusability and storage stability that it remained 27% of its original activity after using for 6 times and 44% after being stored for 33 days. To the lipase immobilized on MCM-41, it declined to 8% by using just 3 times and 35% after 33 days.
