摘要 [目的]研究食用菌苎麻骨培养物对活性艳红X3B染料的脱色效果。[方法]将香菇、平菇和金针菇3种常见食用菌株接种至苎麻骨培养基上培养，研究培养物对50 mg/L活性艳红X3B溶液的降解脱色效果。[结果]

香菇培养物处理3 h对染料溶液脱色率可达92.17%，平菇培养物处理3 h对其脱色率可达72.40%。此外，香菇培养物对该染料溶液具有很好的重复处理效果，但重复处理次数越多脱色效果越差。[结论]香菇和平菇的苎麻骨培养基培养物对活性艳红X3B溶液具有较好的脱色效果。

Abstract [Objective]Decolorization of reacvtive X3B red dye by edible fungus culture in ramie bone medium was studied.[Method] Three edible fungus strains （Lentinus edodes， Pleurotus ostreatus and Flammulina velutiper） were cultured in ramie bone medium and the culturess decolorization effect against 50 mg/L reactive X3B red were studied by detecting the decolorization rate. [Result] The results showed that， the culture of Lentinus edodes in the ramie bone medium could degradate 92.17% reactive X3B red in 3 h， and the culture of Pleurotus ostreatus in the ramie bone medium could degradate 72.40% reactive X3B red in 3 h. The decolorization rate of the culture of Lentinus edodes to treat reactive X3B red repeatly were studied， and the results showed that the culture of Lentinus edodes could also decolorizate reactive X3B red efficiently in 4 times， but the decolorization rate was decreased with the increase of the number of treat times.[Conclusion] The culture of Lentinus edodes and Pleurotus ostreatus in ramie bone medium has good decolorizing effects on reavtive X3B red dye.

紡织印染行业是我国的重要支柱产业之一，但传统的印染行业在生产过程中会产生大量的工业废水，严重污染了环境，在危害周边人群健康的同时也制约了行业的发展。纺织印染行业废水处理方法大致可分为物理法、化学法以及生物法三大类。其中物理和化学处理技术费用高，且会产生大量的固体废物，与之相比，生物法则是经济有效、可被广泛接受的环保处理方法，它运行费用低且无二次污染，符合可持续性发展的需要^[1]。传统的建立在细菌系统上的生物处理技术对非偶氮染料基本没有脱色效果，而一项创新的环境生物技术——真菌技术，能利用一种白腐真菌独特的降解机制，将各种人工合成染料彻底降解为CO₂和H₂O^[2]。……
