Entrapment of Lipases in Hydrophobic Sol-Gel-Materials: Efficient Heterogeneous Biocatalysts in Aqueous Medium

All articles of this category The entrapment of certain lipases such as SP 525 ( Candida antarctica B ) or SP 523 ( Humicola lanuginosa ) in hydrophobic sol-gel materials derived from mixtures of RSi(OMe) 3 (R = alkyl) and Si(OMe) 4 or other alkyl-modified silane precursors results in heterogeneous biocatalysts which are remarkably active in the hydrolysis of esters in aqueous medium. Relative activities of 50-100% are typical. enzymes - catalysis - ester hydrolysis - sol-gel - heterogeneous catalysis
