摘要： A support for immobilizing a biocatalyst and an enzyme immobilized thereon are provided to be harmless to human body and possible to be reused, show increased stability, and be easy to control reactivity, pH and temperature, thereby being widely used in a food or a medicine related industry. A support for immobilizing a biocatalyst comprises silica bead of which an outer layer is crosslinked with chitosan and casein, wherein the silica bead has a pore size of 50-1,000 angstrom. An immobilized enzyme is characterized in that the support for immobilizing the biocatalyst and an enzyme such as alpha-amylase of Bacillus licheniformis are bonded by an amide bond. To degrade starch, the immobilized alpha-amylase is used.
