Efficient Heterogeneous Biocatalysts by Entrapment of Lipases in Hydrophobic Sol–Gel Materials

Abstract

Alkyltrimethoxysilanes yield much better host matrices for lipases than tetramethoxysilane (see picture). This is revealed by the esterifications discussed herein catalyzed by lipases that are immobilized in RSi(OMe)3 gels. These heterogeneous biocatalysts are readily reusable and should also be suitable for continuous processes.
