Abstract
The present invention deals with a process for oxidation of a hydroxy group of C.sub.1 and/or C.sub.2 and/or C.sub.3 and/or C.sub.4 and/or C.sub.5 and/or C.sub.6 of a sugar monomer of an oligo- or a polysaccharide comprising contacting, in an aqueous medium, the oligo- or the polysaccharide with a phenol oxidizing enzyme and an enhancing agent, whereby an oligo- or a polysaccharide with altered characteristics compared to the native oligo- or polysaccharide is created.
Claims6
A process for oxidation of a C.sub.1 and/or C.sub.2 and/or C.sub.3 and/or C.sub.4 and/or C.sub.5 and/or C.sub.6 hydroxy group of a sugar monomer of a starch, said process comprising contacting, in an aqueous medium, the starch with a laccase and an enhancing agent, under conditions in which said oxidation results in formation of a carbonyl or carboxylate group.
