Enzyme immobilization is a technique used to attach enzymes to a solid support, allowing them to remain in a fixed position while still catalyzing reactions. This process enhances the stability and reusability of enzymes, making them more efficient for industrial applications. Common methods of immobilization include adsorption, covalent bonding, and entrapment within a gel or matrix. By immobilizing enzymes, industries can reduce costs and improve the overall efficiency of biochemical processes. This technique is widely used in various fields, including biotechnology, food processing, and pharmaceuticals, where enzymes play a crucial role in producing desired products.
