ABSTRACT:
The stability of granular carrier-bound enzymes is improved by further treating the carrier-bound enzyme with a bifunctional cross-linking agent and a polyamine. A particularly preferred cross-linking agent is glutaric dialdehyde, and a particularly preferred polyamine is polyethylene imine. Preferably, the cross-linking agent is used in an amount of 5 to 250 mg per 1 gram of carrier-bound enzyme and is dissolved in a 0.1 to 10% (W/V) aqueous solution, and the polyamine is used in an amount of 3 to 240 mg per 1 gram of dry carrier and is dissolved in a 0.1 to 20% (W/V) aqueous solution.
