Immobilization of trypsin on alginic acid-poly (glycidyl methacrylate) graft copolymer.
Trypsin was immobilized onto alginic acid-poly(glycidyl methacrylate) graft copolymer (AAGMA). The resulting immobilized enzyme showed 65% of the soluble enzymatic activity. The temperature optimum was shifted by 5 degrees C to a higher value. The pH optimum of immobilized enzyme has also been shifted by 0.5 units toward the alkaline side when compared to that of soluble enzyme. The pH stability and thermal stability are better than that of soluble enzyme.
