Azo dyes containing effluents from different industries pose threats to the environment. Though there are physico-chemical methods to treat such effluents, bioremediation is considered to be the best eco-compatible technique. In this communication, we discuss the decolorization potentiality of five azo dyes by (G. Mey.) Pat., a macro-fungus, found growing on the leaf-litter layer of Bethuadahari Wildlife Sanctuary in West Bengal, India. The fungus exhibited high laccase and very low manganese peroxidase activities under different culture conditions. Decolorization of five high-molecular weight azo dyes, viz., Orange G, Congo Red, Direct Blue 15, Rose Bengal and Direct Yellow 27 by the fungus was found to be positive in all cases. Maximum and minimum mean decolorization percentages were recorded in Rose Bengal (70.41%) and Direct Blue 15 (24.8%), respectively. This is the first record of lignolytic study and dye decolorization by .
不同行业排放的含偶氮染料废水对环境构成威胁。尽管有物理化学方法处理此类废水，但生物修复被认为是最佳的生态兼容技术。在本通讯中，我们讨论了一种大型真菌——（G. Mey.）Pat.对五种偶氮染料的脱色潜力，该真菌生长在印度西孟加拉邦贝图阿达哈里野生动物保护区的落叶层上。在不同培养条件下，该真菌表现出高漆酶活性和极低的锰过氧化物酶活性。发现该真菌对五种高分子量偶氮染料，即橙黄G、刚果红、直接蓝15、孟加拉玫瑰红和直接黄27的脱色在所有情况下均为阳性。最大和最小平均脱色率分别记录在孟加拉玫瑰红（70.41%）和直接蓝15（24.8%）中。这是关于该真菌木质素分解研究和染料脱色的首次记录。
