Immobilization of laccase for biotechnology applications

Laccase played an important role in the decolorization of wide spectrum dyes as a low-cost and environmentally friendly technology. Laccase was immobilized in alginate beads and immobilization conditions were identified. 25 mg/ml laccase enzyme encapsulation efficiencies of using the prepared bead was calculated as approximately 94%. At the end of the 10 days of storage, the free laccase and immobilized laccase retained about 8.08% and 80.83%, respectively. The decolorization of the dye (Direct Blue 2) was around 86% for immobilized enzyme at 45 degrees C. In the study, compared to the free enzyme, high activity, stable, reusable immobilized enzyme preparation was prepared.
