  • 摘要: 从上海闵行区污水处理厂曝气池中的污泥和上海孙桥农业园区农田表层土壤样品中分离得到两株好氧降解菌株:B16-2(曝气池)和N1(农田),都能够不同程度地降解辛基酚聚氧乙烯醚(OPEOn).利用气相色谱质谱联用仪对其好氧生物降解产物进行了表征和鉴别.结果表明,两株菌对OPEOn的好氧生物降解都产生了环境雌激素活性物质———辛基酚,从曝气池中分离出的B16-2好氧降解产生了丁基酚聚氧乙烯醚,从仙人掌土壤分离出的N1菌株降解以羟基端EO链的逐渐断裂为主要途径.
    Abstract: We collected the biological sludge from the aeration tank of shanghai minhang wasterwater treatment plant and topsoil samples from 8 spots where different plants grew in Shanghai Sunqiao agriculture development zone,and the two isolates(B16-2, N1)which can degrade OPEOn were obtained from sludge and cactus soil samples.There bacterial biodegradation intermediates of OPEOn under aerobic conditions were characterized by means of gas chromatogram-mass spectrometry(GC-MS).Base on the observations, both isolates release the estrogenic product——octylphenol,and butylphenol biethoxylate was obtained from bacterium B16-2 biodegradation products,the scission of EO chains from their hydroxyl terminalside is the predominant biotranformation mechanism of N1.All studies made the foundation for the further research of OPEOn traformation.
