Title: Shigeki Shigesada: Innovator in Enzyme Immobilization
Introduction
Shigeki Shigesada is a notable inventor based in Sagamihara, Japan. He has made significant contributions to the field of enzyme immobilization, holding 2 patents that showcase his innovative approaches.
Latest Patents
One of his latest patents focuses on the immobilization of enzymes on granular gelatin. This process involves simultaneously reacting a non-proteolytic enzyme and a water-soluble multifunctional reagent with non-hardened granular gelatin in an aqueous medium. The reaction occurs in the presence of a water-soluble protein polymer compound, which enhances the bond between the enzyme and the gelatin. The result is a uniform film formed on the surface of the granular gelatin, strengthening the immobilization process.
Another patent details a process for producing immobilized enzyme compositions for industrial use. This method includes reacting an enzyme or enzyme-containing microorganism cells with an anion-exchange high molecular substance that contains a quaternary pyridine ring. The reaction products are then molded and dried in a molding machine, with the option to add a polyfunctional crosslinking agent at any stage. The resulting immobilized enzyme compositions are suitable for packing in industrial-scale reactors for continuous enzyme reactions.
