| 摘 要： | 以石油为唯一碳源，从被石油污染的玉门油田土壤中，分离、筛选出2株高效降解石油的茵株A和B，研究了它们对原油的降解能力．结果表明，经12d后，A、B对原油的降解率分别可迭61．71％和53．12％．GC-MS分析表明，饱和烃中的正构烷烃、烷基环己烷、烷基苯和二环烷均能被明显降解，芳香烃中的萘和烷基萘经降解后几乎消失，菲和烷基菲经菌A作用后发生明显降解．茵株经鉴定，二者均为芽孢杆茵．

| Abstract: | Using petroleum as the sole carbon source,two bacteria strains(A and B), which have high degrading capacity for crude oil, are isolated and screened out from petroleum-polluted soil in Yumen oil-field, and their degradation ability are studied.The results show that after 12 days the degradation rate of the strains A and B are 61.71% and 53.12%,respectively.GC-MS analysis indicates that in the saturate hydrocarbons,n-alkane, alkyl cyclohexane and dicycloalkane could be degraded obviously; in the aromatic hydrocarbons, naphthalene and alkyl naphthalene almost disappeared after degradation; phenanthrene and alkyl phenanthrene are degraded obviously by the strain A. The two strains are identified as bacillus. |
