摘　　要：从某纺织印染厂附近的污泥中筛选、分离、纯化得到一株三苯甲烷类染料脱色菌株,并研究了该菌株对龙胆紫染料的最佳脱色降解条件。实验结果表明,该菌在pH值为7.0、温度为35℃、培养时间为96h的条件下,对浓度为30mg/L的龙胆紫染料的脱色率达74%以上。A strain of triphenylthane dye decolouring bacteria is obtained through screening, separation and purification from the sludge nearby a textile dyehouse and its optimal decolouring process for gentian violet is investigated. The experimental results show that when the bacterium is cultured at 35℃,pH=7.0, for 96 hours, its decolouring rate for gentian violet with a concentration of 30mg/L reaches above 74%.
