摘　　要：为了探索微生物对偶氮染料的降解,采用驯化筛选方法从洗染工厂污泥中获取一株菌株NN-65,并通过摇瓶降解试验对其降解特性进行初步研究。在50 mg/L直接耐晒耐酸大红染料溶液的摇瓶降解试验中,确定了最佳条件:接种量10%,pH 7.5,温度40℃,转速200 r/min,降解时间20 h。在最佳条件下,降解率是90.5%,达到最高。To study degradation of azo dye by microorganisms, a strain denoted NN-65 was isolated from sludge of a textile factory by numerous acclimation and screen. The azo dye degradability was studied by using shake-flask culture for 24 h. When the initial concentration of directly acid bright red was 50 mg/L, the best degradation conditions were determined as follows： inoculation volume of 10 %, pH of 7.5, temperature of 40 ℃ and rotation speed of 200 r/min. Under the optimal conditions, the maximum degradation rate of 90.5 % was received.
