Immobilization of lipase in cage-type mesoporous organosilicas via covalent bonding and crosslinking
Publikováno v:
Catalysis Today. 243:173-183
Lipase from Thermomyces lanuginosus (TLL) was immobilized in cage-type mesoporous materials via two different protocols, viz. covalent bonding and cross-linking. The comparison between the biocatalysts generated by the two methods on both pure silica
