Enzyme immobilization provides easy recovery and reuse of enzyme and many other advantages, including ease in product separation and continuous operation Immobilized enzymes have got a great development. In this paper, Research progress of immobilized enzyme is introduced adsorption, covalent binding and entrapping methods. Studies on modified carrier梞agnetic polymer bead are summarized. It is pointed out that the new type, high efficiency immobilized enzyme technology by modificating natural polymer carrier and combining with the present new technology will be the development of future research.
