| 摘 要： | 以多环芳烃(PAHs)菲、蒽、芘、■和苯并(a)芘为供试物,对土著混合菌和引进菌同时进行筛选实验。结果表明,引进菌和土著混合菌经过驯化后对菲、蒽、芘、■和苯并(a)芘均具有一定的降解能力。其中,在pH=6时,混合菌U03在48h内对5种PAHs的降解率均相对较高,分别为:72.38%;64.46%;65.77%;66.49%和64.77%,并且其的降解速率在各菌剂中同样最快,通过SPSS数理统计分析软件对数据进行处理后得出,混合菌U03可在较短时间内达到较好的降解目的。室内模拟试验证明混合菌U03具有较强的降解PAHs的能力,混合菌的协同作用有利于污染土壤中PAHs的降解。

| Abstract: | With phenanthrene,anthracene,pyrene,chrysene and benzo(a)pyrene as experiment materials,indigenous mix-microorganism and introduced strains were simultaneously screened in our lab.The experiment results showed that both indigenous mix-microorganism and introduced strains after-domestication were capable of degrading phenanthrene,anthracene,pyrene,chrysene and benzo(a)pyrene,respectively.At pH=6,there were relatively high rate of degradation of the five kinds of PAHs by mix-microorganism U03 within 48 hours,... |
