Hydrogen peroxide generation with immobilized glucose oxidase for textile bleaching.
Glucose oxidase was covalently immobilized on commercially available alumina and glass supports, with a high level of protein recovery. The operational stability of the alumina carrier was an advantage over the glass support, though the rate of generation of hydrogen peroxide in the case of the latter was higher. The immobilization technique provided repeated application of the enzyme even in low concentration, and the hydrogen peroxide generated in the enzymatic reaction was successively used for textile bleaching.
