In a variety of sectors, synthetic dyes are frequently employes. Such dyes are extremely poisonous, mutation-causing, cancer-causing and also causes various ill effects to the environment. Current study demonstrates the potential of Ganoderma lucidum to decolorize synthetic textile dyes that are recalcitrant. In the course of fermentation of natural lignocellulosic substrate i.e., wheat bran, G. lucidumi predominantly secretes laccase as major lignolytic enzyme. Pure enzyme had a very high decolorizing efficiency against Remazol Brilliant Blue R (RBBR), an anthraquinone dye, without the involvement of a redox mediator, but it needed a redox mediator to decolorize Remazol Black-5 (RB-5), a di-azo dye. The role of laccase enzyme as the main enzyme behind the degradation of both the dyes were confirmed by Polyacrylamide Gel Electrophoresis (PAGE). 1mM concentration of N-Hydroxybenzotriazole (HBT) was established as the prime redox mediator. Time taken by crude enzyme (25U ml-1) to decolorize RBBR (50mg/L) by 90% was 2h when no redox mediator was present whereas it took 2h to decolorize RBBR by 92% when a redox mediator was present. In case of RB-50 dye, the crude enzyme took 1h and 2h to decolorize RBBR by 62% and 77.4%, respectively without the use of any redox mediator
