%X Laccase extracted from the Amillariella mellea fermentation catalytic decolored on two common anthraquinone dyes: Reactive Brilliant Blue KN-R and Reactive Brilliant Blue X-BR which is broadly used in the printing and dyeing industry and obtained the optimal catalytic decolorizing conditions. The results showed that optimum temperature of Reactive Brilliant Blue KN-R decolorization was 30 degrees C, the optimum dye concentrations was 80 mg x L(-1), the optimum enzyme dosage was 0.25 U x mL(-1), and the optimum pH was 5. Under this optimal conditions, the maximum decolorization rate of Reactive Brilliant Blue KN-R was over 90%. The optimum temperature Reactive Brilliant Blue X-BR decolorization was 30 degrees C, the optimum dye concentrations was 50 mg x L(-1), the optimum enzyme dosage was 0.5 U x mL(-1), and the optimum was pH 4. Under the optimal conditions, the maximum decolorization rate of Reactive Brilliant Blue X-BR was over 70%. The decolorization on the two common industrial dyes by crude enzyme from Amillariella mellea fermentation obtained a good results. The results indicated that the decoloration on anthraquinone dyes by laccase from Amillariella mellea has a potential value in the printing and dyeing industry.
