  • Immobilization of enzymes using recycled support materials
    Patent number: 4087330
    Abstract: Immobilized enzyme composites comprising enzymes bonded to porous, high surface area support materials can be economically prepared by contacting "spent" composites with a solution of NaOCl to remove substantially all contaminants resulting from previous use of the composites and then reacting the cleaned support materials with a solution of active enzymes under conditions sufficient to permit the bonding of enzymes to the surfaces of the support materials.
    Type: Grant
    Filed: December 23, 1976
    Date of Patent: May 2, 1978
    Assignee: Corning Glass Works
    Inventors: Jerry L. Gregory, Wayne H. Pitcher, Jr.
  • Enzyme carrier regeneration
    Patent number: 4002576
    Abstract: Highly porous MgO-Al.sub.2 O.sub.3 particulate support materials useful for the immobilization of glucose isomerase can be regenerated for reuse by circulating a sodium hypochlorite solution through the particles thereby permitting in situ enzyme carrier regeneration.
