Optimal immobilization of β-glucosidase into chitosan beads using response surface methodology
Background: β-Glucosidase is known as an effective catalyst for the hydrolysis of various glycosides and immobilization is one of the most efficient strategies to improve its activity recovery and properties. Results: Crosslinking-adsorption-crosslinking method was employed to immobilize &a...
