Immobilized enzyme, preparation method and use thereof

Abstract

Provided is an immobilized enzyme, a preparation method and use thereof. The immobilized enzyme includes an enzyme and an amino resin carrier for immobilizing the enzyme, and the enzyme is selected from any one of the following enzymes: transaminase, ketoreductase, monooxygenase, ammonia-lyase, ene reductase, imine reductase, amino acid dehydrogenase, and nitrilase. The amino resin carrier is an amino resin carrier modified by a cross-linking agent, and the cross-linking agent is a cross-linking agent treated by a polymer. By means of modifying the amino resin carrier with the cross-linking agent treated by the polymer, the enzyme immobilized on the amino resin carrier may easily form a network cross-linking, such that the immobilization effect of the enzyme is more stable, thereby the recycling efficiency of the enzyme is improved.

Dependencies are inferred from the claim text.
