Enzyme immobilization strategies for the design of robust and efficient biocatalysts
Current Opinion in Green and Sustainable Chemistry(2022)
Abstract
Different strategies for the preparation of efficient and robust immobilized biocatalysts are here reviewed. Different physico-chemical approaches are discussed. i.-The stabilization of enzyme by any kind of immobilization on pre-existing porous supports. ii.-The stabilization of enzymes by multipoint covalent attachment on support surfaces. iii.-Additional stabilization of immobilized-stabilized enzyme by physical or chemical modification with polymers. These three strategies can be easily developed when en-zymes are immobilized in pre-existing porous supports. In addition to that, these immobilized-stabilized derivatives are optimal to develop enzyme reaction engineering and reactor engineering. Stabilizations ranging between 1000 and 100,000 folds regarding diluted soluble enzymes are here reported.
