DESCRIPTION

Immobilization is defined as the imprisonment of cell or enzyme in a distinct support or matrix. The support or matrix on which the enzymes are immobilized allows the exchange of medium containing substrate or effector or inhibitor molecules. Advantages of immobilized enzymes are Increased functional efficiency of enzyme, Enhanced reproducibility of the process they are undertaking, Reuse of enzyme, Continuous use of enzyme, Less labour input in the processes, Saving in capital cost and investment of the process, Minimum reaction time, Less chance of contamination in products, More stability of products, Stable supply of products in the market, Improved process control and High enzyme substrate ratio. Methods of Immobilization: Based on support or matrix and the type of bonds involved, there are five different methods of immobilization of enzyme or whole cells, they are Adsorption, Covalent bonding, Entrapment, Copolymerization and Encapsulation
