Enhanced Stability of α-Amylase via Immobilization onto Chitosan-TiO2 Nanocomposite

low stability, high cost and high selectivity towards the reaction conditions, they are limited to industrial applications [1-3]. In order to facilitate their usage in industrial applications several developments have been done in the field of enzyme technology during the last two decades [4]. Immobilization of enzymes on solid supports has become most familiar technique after Nelson and Griffin have done the immobilization of invertase onto charcoal hydrolyses sucrose via adsorption in 1961 [5]. Immobilization provides many advantages, such as continuous operations in enzyme reactor, enhanced stability, reusability and easy separation from reaction mixture [6]. The introduction of immobilized catalysts has greatly improved both the technical performance of the industrial processes and their economy.
