Amyloglucosidase from A. niger was covalently immobilized onto poly(GMA-co-EGDMA) by the glutaraldehyde and periodate method. The immobilization of amyloglucosidase after periodate oxidation gave a preparate with the highest specific activity reported so far on similar polymers. The obtained immobilized preparates show the same pH optimum, but a higher temperature optimum compared with the soluble enzyme. The kinetic parameters for the hydrolysis of soluble starch by free and both immobilized enzymes were determined.
Amiloglukozidaza iz A.niger je imobilizovana na poly(GMA-co-EGDMA) glutaraldehidnom i perjodatnom metodom. Imobilizacija amiloglukozidaze nakon perjodatne oksidacije daje preparat sa najvećom do sada objavljenom specifičnom aktivnosti na sličnim polimerima. Dobijeni imobilizovani preparat ima isti pH optimum ali povećani termooptimum u poređenju sa rastvornim enzimom. Određeni su i kinetički parametri za hidrolizu rastvornog skroba imobilizovanim kao i rastvornim enzimom.
