Preliminary study on decolorization of indigo dye wastewater with laccase from Trametes versicolor 1126
云芝Trametes versicolor1126所产漆酶对靛蓝废水脱色的初步研究

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.
