AaCel9A [β-1,4-endoglucanase, (E.C:3.2.1.4)], was immobilized onto glutaraldehyde activated chitosan macrosphere by covalent attachment. The properties of the immobilized AaCel9A were investigated by determining the optimum pH and optimum temperature for activity, thermal stability, and kinetic parameters. The immobilization process shifted the enzyme’s optimum temperature from 65 °C for the fr...
