RESUMO
Condition optimization for immobilization of Fungal laccase with Nylon Net and glutaraldehyde and the nature of the immobilized enzyme were studied. The optimum conditions of the immobilization are: Nylon Net is crosslinked with 5% glutaraldehyde 15mL for 6 hours; the 30U laccase is added for immobilization for 8 hours. On this case, the recovery of enzyme activity was 50.3%. Compared with free enzyme, the thermal stability of immobilized enzyme was improved evidently but the optimal pH decreased slightly. 52% enzyme activity of immobilized laccase was hold after 8 cycles treatment with low concentration pulp wastewater.
