Abstract
Immobilized enzyme-polysaccharide graft copolymer products are prepared by hydrolyzing a polysaccharide graft copolymer and then contacting the hydrolyzed copolymer with an enzyme to immobilize the enzyme on the copolymer. The copolymer-enzyme products retain large quantities of active enzyme, and activity of the enzyme is retained over long periods of use. In the case of glucoamylase immobilized in accordance with the method of the invention, improved yield of glucose from starch is obtained.
