NU2 for degradation of five synthetic dyes. Sawdust, wheat bran, banana peel and tangerine peel were used as carbon sources for bacterial growth and laccase production. Tangerine peel yielded the most laccase. The purified enzyme decolourized Congo Red, Methyl Orange, Remazol Brilliant Blue R, Reactive Blue 4 and Malachite Green by 87%, 70%, 65%, 63% and 51%, respectively. The laccase showed high catalytic potential for detoxifying dye effluents in environmental systems.Article10.1080/13102818.2022.2053341
