Covalent immobilization of glucoamylase enzyme onto chemically activated surface of κ-carrageenan

Background Glucoamylase enzyme is one of the most important enzymes. It catalyzes the hydrolysis of starch into soluble sugars. It was covalently immobilized onto κ-carrageenan gel beads after activation by using polyethylenimine (PEI) followed by glutaraldehyde (GA). All parameters in activation process were studied.
