Preparation and properties of immobilized amyloglucosidase

Journal Article · · Biotechnol. Bioeng.; (United States)
Amyloglucosidase was immobilized on a copolymer of methyl methacrylate and 2-di-methylaminoethyl methacrylate. The resulting immobilized amyloglucosidase has 19% of the soluble enzyme specific activity. The pH optimum of immobilized amyloglucosidase is shifted towards acidity by 1.9 units. The temperature optimum of immobilized enzyme is shifted upward by 5 degrees C. The immobilized amyloglucosidase has the maximum stability at pH 4.6, whereas the soluble enzyme has maximum stability at pH 5.5. While soluble amyloglucosidase has a maximum thermal stability at 50 degrees C, the stability of the immobilized amyloglucosidase steadily decreases with the increase in temperature. (Refs. 7).
