title: Immobilization of lipase on epoxy activated (1-->3)-alpha-D-glucan isolated from Penicillium chrysongenum.
abstract: A water-insoluble linear (1-->3)-alpha-D-glucan was isolated from Penicillium mycelia. Three kinds of epoxy-activated microspheres of this glucan were prepared as supports for Candida sp. lipase (EC3.1.1.3) immobilization. The highest immobilization yield was 36.4%. The specific activity was 26.85 U/mg, and only 4.1% of activity was lost in comparison with the free enzyme used for immobilization. The higher thermal stability, storage stability, and reusability of the immobilized lipase make it a potential candidate for wide application.
