Silica mesoporous material MCFs with 16.0 nm pore sizes was prepared by using non-ionic block copolymers and the swelling agents, and was used as the support for the immobilization of enzyme. Penicillin G acylase, an enzyme, was assembled in the channel of MCFs by immersion method. The activity and stability of immobilized penicillin G acylase were studied. It was found that the activity and stability of the immobilized penicillin G acylase increased significantly compared to those of free enzyme. The ...
