ABSTRACT:
An immobilized enzyme having high activity and stability is obtained by immobilizing an enzyme on a water-insoluble amino group-containing carrier by use of a polyfunctional cross-linking agent such as glutaraldehyde in the presence of a phenolic carboxylic acid having one or more hydroxyl groups such as tannic acid. In addition to the phenolic carboxylic acid, a basic polysaccharide such as chitosan may also be present. The amino group-containing carrier may be aminated silica gel, aminated porous glass, aminated zeolite, or water insoluble crosslinked chitosen.
