Trametes hirsuta and Pleurotus florida showed the greatest extent of decolorization on nutrient salt media. Maximum decolorization of 200 mg/l of Blue 133 was obtained by 4 days old incubated Pleurotus florida followed by Trametes hirsuta after 6 days. An attempt was made to improve the decolorization activity of both organisms with different concentrations of glucose 1 and 2% (w/v). The decolorization activity may be due to the laccase enzyme of white rot fungi. The production of this enzyme was estimated using solid state fermentation with rice bran as a substrate. It was found that P. florida exhibited 0.175 U/ml of laccase activity followed 0.126U/ml by T. hirsute, respectively. Decolourization was found to be more effective with P. florida in the presence of 2% (w/v) glucose. Crude extract containing the laccase enzyme was isolated and confirmed by SDS PAGE}, keywords = {Dye house effluent,Laccase,Pleurotus florida,reactive textile dyes,Trametes hirsuta}, url = {https://www.ijbiotech.com/article_7030.html}, eprint = {https://www.ijbiotech.com/article_7030_668dfcef961b0e1f6af7f806ec70d6e5.pdf} }
