Commercial enzyme preparations catalyse feruloylation of glycosides

Commercial enzyme preparations from Humicola insolens, Thermomyces lanuginosus and Aspergillus niger were tested for transesterifications of ferulic acid from its active esters to various glycosides at their primary hydroxyl group. Use of Lipolase 100T (from T. lanuginosus) was optimized for these syntheses in preparative scale.
