  • Process for the renewal of an insolubilized glucose isomerase
    Patent number: 4205127
    Abstract: There is disclosed a process for the renewal of a deactivated insolubilized glucose isomerase which comprises subjecting an insolubilized glucose isomerase adsorbed onto an anion exchange resin, which has been used for isomerization of glucose into fructose to decrease its activity, to treatments by an aqueous mineral acid solution in combination with an aqueous alkaline solution, an aqueous electrolytic salt solution, an aqueous mineral acid or a mixture thereof to release adsorbed materials from the resin which is converted into a salt type and adsorbing fresh glucose isomerase to the regenerated resin to recover the activity of the insolubilized glucose isomerase.
    Type: Grant
    Filed: June 20, 1978
    Date of Patent: May 27, 1980
    Assignees: Mitsubishi Chemical Industries, Limited, Seikagaku Kogyo Company, Ltd.
    Inventors: Yoshimasa Fujita, Akiyoshi Matsumoto, Isao Miyachi, Nobuo Imai, Isao Kawakami, Tadashi Hishida, Akira Kamata
