Adsorption of lipases on porous silica-based materials for esterification in a solvent-free system.

This study deals with lipase immobilization on micro- and mesoporous silica-based materials. The effects of the type of support (silica MCM-41, zeolite HZSM-5 (SAR 25), zeolite HZSM-5 (SAR 280), and the silica-aluminas Siral 10, Siral 20, and Siral 40) were investigated on the immobilization of lipase B from (CALB) and lipase from (RML). The supports that allowed the highest immobilization efficiencies for the CALB were Siral 40 (91.
