摘　　要：考察了云芝Trametes versicolor1126发酵培养中漆酶酶活和pH的变化,同时研究了羧甲基纤维素钠及苯酚添加量对漆酶活力的影响。结果表明当培养基中加入0.8%羧甲基纤维素钠、100mg/L苯酚时,均能明显提高漆酶的活力。以漆酶/HBT介质体系对靛蓝废水进行脱色,反应100min后,脱色率达90.8%。使用漆酶处理靛蓝废水具有广阔的应用前景。The dynamic variation of laccase activity and pH were detected during fermentation of Trametes versicolor 1126. The effects of sodium carboxymethyl cellulose and phenol on laccase activity were also studied. The results indicated that 0.8% sodium carboxymethyl cellulose and 100mg/L phenol in the medium can enhance the activity of laccase obviously. Indigo dye wastewater was degraded in laccase/HBT mediator system. The decolorization rate reaches 90.8% in 100 minutes. A practical way using laccase to decolorize indigo dye wastewater has extensive prospect.
