  • Title: [Preparation and properties of immobilized glucose oxidase].
    Author: Kühn W, Kirstein D, Mohr P.
    Journal: Acta Biol Med Ger; 1980; 39(11-12):1121-8. PubMed ID: 7245983.
    Abstract:
    Glucose oxidase from Penicillium notatum was immobilized by covalent, adsorptive or ion exchange attachment to insoluble carriers. The yields of immobilization using Spherons, DEAE-Sephadex, DEAE-cellulose and porous glass carriers are compared. Methods used for the estimation of kinetic parameters Km and kcat are described and results obtained for GOD in solution and in immobilized form are given. Investigations about the dependence of the enzymatic activity on pH, temperature and storage serve for the further characterization of the GOD-derivatives. There are no significant changes in the functional behaviour of the enzyme due to immobilization on selected carriers. The results are discussed with regard to application of carrier bound GOD in enzyme reactors.
