Maltase is an enzyme that catalyzes the hydrolytic process of α-1→4 glycosidic linkages and yields α-D-glucose as an end product. Maltase is used in different industries like food, brewing, distilling and pharmaceutical industry . Catalytic property of an enzyme is one of the critical aspects for its commercialization and in some cases free enzymes are unstable to fulfill the requirement of industries due to low operational stability and recovery. Various techniques such as protein engineering, chemical modification and immobilization have been investigated to overcome the limitation of enzymes for industrial bioreactors and . Immobilization is an encouraging approach that not only enhances the stability of enzymes but also ensures the reusability of enzymes for various industrial bioprocesses and Different immobilization techniques including covalent binding, adsorption, crosslinking and entrapment are used for continuous use of different enzymes on industrial scale. Among them, entrapment confines the enzyme within the structured matrix space and create negligible impact on its catalytic properties and There are various matrices such as alginate, polyacrylamide and agar–agar are employed for enzyme immobilization. Alginate is an anionic polysaccharide distributed widely in the cell walls of brown algae and commonly used for the formation of beads capable of entrapping different macromolecules in the form of calcium-alginate beads and Calcium alginate is a cost effective and biocompatible matrix for the entrapment of different enzymes including α-amylase, protease and pectinase and .
