摘 要：
[目的]研究裂褐菌对刚果红染料脱色的影响。[方法]通过控制培养基中Mn2+的浓度,获得只有木质素过氧化物酶(LiP)或锰过氧化物酶(MnP)的单一酶和两者的混合物,探讨裂褐菌对刚果红染料的脱色效果。[结果]LiP、MnP及LiP和MnP的粗酶液在1 h内对4种浓度的刚果红染料进行降解过程中,35 mg/L的刚果红的降解效果较佳,最高可分别达24.77%、20.31%、23.47%。3种培养物对刚果红都有明显的脱色效果,5 mg/L的脱色效率均在95%左右,20 mg/L的脱色效率超过80%,35 mg/L的脱色效率在80%左右,50 mg/L的脱色效率在70%左右。[结论]该研究为染料废水处理提供参考依据。

摘 要：
[Objective] The research aimed to study the decolorization effects of Schizophyllum commune on Congo red.[Method] The concentration of Mn2+ in N-limited submerged culture was controlled to obtain LiP,MnP and LiP-MnP created by Schizophyllum commune.The decolorization effects of Schizophyllum commune on Congo red dye were studied.[Result] The results indicated that during the degradation process of LiP,MnP and LiP-MnP crude enzyme removing 4 concentrations of Congo red in 1 h,35 mg/L Congo red degradation effect was better,the highest decolorization rate could reach 24.77%,20.31% and 23.47%,respectively.The cultures of LiP,MnP and LiP-MnP had obvious decolorization effects on Congo red,about 95% decolorization rate for 5 mg/L Congo red,80% decolorization rate for 20,35 mg/L Congo red,and about 70% decolorization rate for 50 mg/L Congo red.[Conclusion] The study can provide the reference for the dye waste water treatment.
