Studies of Optimum Conditions for Cross-linking Immobilization of Alkaline Protease on Graphene Oxide
Graphene oxide was used as substrate for immobilizing alkaline protease. The immobilizing conditions were optimized though single-factor test and orthogonal design. Then the activity recovery was raised to 92.0% and 70.1% in the optimum conditions of immobilization. The test indicated that the optimum technics were as follows: the enzyme amount to 1 mg carriers was 500(xl, the concentration glutaraldehyde is 1%, pH was 8.0, temperature was 25°C, crosslinking time and absorption were 4 hours and 1 hour, respectively, the recycling rate of activity (RRA) reached 70.1%.
