Immobilization and Stabilization of Aspergillus Fumigatus ?-Amylase by Adsorption on a Chitin

In this research, immobilization of A. fumigatus ?-amylase on chitin was studied with the main purpose to improve characteristics enzyme. A series experiments were carried out study stability improvement, thermodynamic parameters, include ki, ?Gi, and t½, reusability immobilized The experimental results indicate that significant thermal achieved, as indicates by ability enzyme retain its relative activity above 39% after 80 min incubation at 60oC. Thermodynamic is more rigid, stable, less flexible in water, resulting increased up 1.5 times compared native Furthermore, able over 46% initial six consecutive applications for starch hydrolysis, confirming potential production enzymes an industrial scale.
