Immobilization of enzymes on chitin and chitosan

During the last few years, d-glucose isomerase, glucoamylase, β-d-galactosidase (lactase), β-d-glucosidase, d-glucose oxidase, AMP deaminase, urease, pronase, subtilisin, trypsin, papain, alkaline phosphatase, acid phosphatase, pepsin, chymotrypsin and lysozyme have been immobilized on chitin and on some of its derivatives, mainly with glutaraldehyde. The preparation and performances of the immobilized enzymes are described.
