Cellulose / waste Cu2+-activated carbon composite: A sustainable and green material for boosting laccase activity and degradation of bisphenol A in wastewater

Low enzyme activity is one of the disadvantages of immobilized laccase. In this study, waste Cu2+-loaded activated carbon (Cu-AC) was successfully used in preparing a novel composite support,cellulose / Cu2+-loaded activated carbon beads (C / Cu-AC), and effectively boosted immobilized laccase activ...

description Low enzyme activity is one of the disadvantages of immobilized laccase. In this study, waste Cu2+-loaded activated carbon (Cu-AC) was successfully used in preparing a novel composite support,cellulose / Cu2+-loaded activated carbon beads (C / Cu-AC), and effectively boosted immobilized laccase activity. To achieve optimum conditions for immobilization of laccase, the immobilization time, pH and laccase concentration were examined. The highest immobilized laccase activity (34.21 U/g) was achieved under optimum conditions (T = 4 h, pH = 4, C = 5 g/L), which was increased by 35.86 % compared to control. In addition, the immobilized laccase showed an outstanding performance in thermostability and reusability compared to free laccase. Moreover, the degradation of BPA by immobilized laccase was carried out, and the optimum degradation conditions were explored. Under such conditions: concentration of BPA was 75 mg / L and pH = 4, t = 1 h, T = 50 °C,the removal yield of BPA reached a maximum of 79.88 %. Therefore, the utilization of waste Cu-CA is a powerful method to boost immobilized laccase activity and creating a new way to high value treatment of waste Cu-CA. [Display omitted] •Waste copper-loaded activated carbon from plant was utilized.•Immobilized laccase activity was improved by waste copper-loaded activated carbon.•> 50 % of enzyme activity was retained after 10 cycles.•Bisphenol A (BPA) was degraded more effectively by immobilized laccase.
