从工厂排污口废水中分离．纯化并筛选出一株降解十二烷基聚氧乙烯醚（Brij-30）的菌株，鉴定为伯克氏菌属（Pandoraca sp），命名为B30．当温度为30℃，pH5～8，底物浓度低于0．2g/L，且以蛋白胨做氮源时，菌株B30降解效果最好；Zn~(2＋)Ca~(2＋)、Al~(3＋)、Fe~(3＋)对菌株B30的生长及其降解性能具有较大的促进作用．在低浓度区（0．05-0．20g／L），菌株B30生长最快，降解活力性最强，12h内能将底物基本降解；在中等浓度区（0．40g，L左右），72h内能降解50％的底物；在高浓度区（0．80-1．50g/L），72h内底物的降解率在30％以下．

A bacterial strain B30 of degrading 12 alkyl-polyoxyethylene (Brij-30) was isolated, purified and sorted from the wastewater in pollution-outlets of a factory, and identified as Pandoraea sp.. At temperature of 30°C, pH of 5~8, Brij-30 concentration lowered 0.20g/L, protein peptone as the nitrogen source, bacterial strain B30 degradation effect was the best. ZnO2+, Ca2+, Al3+, Fe3+ had greater promoting effect on the growth of bacterial strain B30 and its degradation property. At low concentration area (0.05~0.20 g/L), bacterial strain B30 gre...
