摘　　要：采用漆酶DENILITEⅡ对活性染料染液进行催化脱色。对于0.1 g/L雷马素藏青RGB染液,优化的脱色工艺为:漆酶DENILITEⅡ1.0 g/L,pH值8,60℃处理3 min。在该工艺条件下,雷马素藏青RGB染液的脱色率为91%;对丽华实蓝CA及红CA染液催化脱色效果也较好,对诺威克隆橙C-3R几乎无脱色效果。硫酸钠对漆酶的活性有抑制作用。通过响应面优化法和回归分析,得出在漆酶DENILITEⅡ1.0 g/L、p H值7.8、65℃处理3 min时,获得脱色率理论最大响应值93%。The decolorization of reactive dye with DENILITE Ⅱ （Laccase） is carried out. The optimum decolorization process for 0.1 g/L Remazol Navy Blue RGB is treating at 60 ℃ for 3 min with 1.0 g/L DENIL- ITE Ⅱ and pH value of 8. Under this conditions, the decolorization rate of Remazol Navy Blue RGB can reach 91%. Good decolorization results can also be achieved for Levafix Blue CA and Levafix Red CA, but little effect for Novacron Orange C-3R. Sodium sulfate has inhibitional effect on activity of DENILITE Ⅱ. According to the response surface methodology and regression analysis, the maximum theoretical response value is 93% under the conditions of Denilite Ⅱ1.0 g/L, pH value 7.8, treating at 65 ℃ for 3 min.
