| 摘 要： | 直链烷基苯磺酸盐（Linear Alkylbenzene sulphonate，简称LAS）是一类阴离子表面活性剂，为合成洗涤剂的主要成分，具有一定的毒性。利用生物法降解100mg／kg以上的高浓度LAS的研究较少。笔者从环境中筛选出一株能以LAS为唯一碳源生长的高抗性LAS降解菌株，对其降解特性进行了研究。

| Abstract: | A IAS degradation strain with kigh resistance,which could take linear alkylbenzene sulphonate(LAS)as only carton origin for growth,was isolated from the drain canal of Hangao Detergent Plant of Xuzhou.The characteristic of its degradation was researched and the results showed that the optimum conditions of this strain for degrading LAs were 30 ℃,pH 6.0,150 ml solution in 500 ml triangle vase,120 r/min,LAS concentration of 200-600 mg/L.The growth amount of the bacteria were up to 0.443(OD460)and the degrading rate was up to 89.4%. The ability of the bacterium to degrade LAS could be as high as concentration of 1 200. mg/L. |
