食用菌苎麻骨培养物对活性艳红X-3B染料脱色研究

Decolorization of Reacvtive X-3B Red Dye by Edible Fungus Culture in Ramie Bone Medium

[目的]研究食用菌苎麻骨培养物对活性艳红X-3B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X-3B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X-3B溶液具有较好的脱色效果。

[Objective]Decolorization of reacvtive X-3B 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 cultures＇ s decolorization effect against 50 mg / L reactive X-3B 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 X-3B red in 3 h,and the culture of Pleurotus ostreatus in the ramie bone medium could degradate 72. 40% reactive X-3B red in 3 h. The decolorization rate of the culture of Lentinus edodes to treat reactive X-3B red repeatly were studied,and the results showed that the culture of Lentinus edodes could also decolorizate reactive X-3B red efficiently in4 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 X-3B red dye.
