Lipases SP525, AK, LIP, and PS were immobilized on three kinds of mesoporous silicates (FMS, PESO, and SBA) with diameters of 27 to 92 A. The amount of lipase activity adsorbed on these supports was related to the pore size of the silicate. Enantioselectivities of immobilized lipases were similar to those of free lipases, and recycling could be done in both aqueous and organic solvents.
Asymmetric transesterification of secondary alcohols catalyzed by feruloyl esterase from Humicola insolens

A new asymmetric transesterification of secondary alcohols catalyzed by feruloyl esterase from Humicola insolens has been found. Although alcohols are not the natural substrates for this enzyme, a high R enantioselectivity was observed. Stereochemical studies showed that variations in substrate structure lead to strong variations in enantioselectivity. The highest enantioselectivities are obtained when the β-carbon of the secondary alcohol is tertiary or quaternary.
