In this study a microbial system for biphenyl biodegradation is set up in order to investigate the effects of surfactants on biodegradation of hydrophobic organic compounds . four strains which can grow on biphenyl as the sole carbon and energy sources are selected out , in which alcaligenes eutrophus dj1 and pseudomonas sms02 are chosen as degradation strains . after studing the bioavailability of three nonionic surfactants ( op - 10 , tween - 80 , and triton x - 100 ) , they are added into the biodegradation system of biphenyl 为了考察表面活性剂对疏水性有机污染物生物降解的影响，本论文选择联苯作为模拟研究体系，筛选、驯化得到四株可利用联苯作为碳源生长的菌株；考察了联苯降解菌株对三种非离子表面活性剂op - 10 、 tween - 80 、 tritonx - 100的生物可利用性；用高效液相色谱法测定了非离子表面活性剂对联苯的增溶曲线；较系统地研究了加入非离子表面活性剂对联苯生物降解速率的影响。
Abstract : renews in this paper of the surfactant oil based for surface activies agent of anionic ( alcohol sulfate , sulfonata , acetyl cyanamid , and oleie methyl ester sulfonat etc . ) surface a ctivies agent of nonionic ( apg , alcohol polyxyethnyl ether , alkyl polyoxyethnyl alnyl hydroxyl ether etc . ) , for technique improvement and develcpment trends 文摘:综述了油基表面活性剂中阴离子表面活性剂(醇硫酸盐， -磺酸盐、酰基氰胺、油酸甲酯磺酸盐等) ，非离子表面活性剂( apg 、脂肪醇聚氧乙烯烷基醚、烷基聚氧乙烯烷基羟基醚等)的技术进展及今后发展趋势。
