| 摘 要： | 从炼油厂污水池底泥中富集、驯化、分离、筛选,得到4种优势石油降解菌。采用摇床培养,研究了各优势
菌和混合菌对石油烃的降解性能。结果表明:4种菌和混合菌20d可将初始质量浓度为10000mg/L的石油烃
依次降解90.8%、88.9%、57.8%、49.8%、91.2%;培养液中石油烃的半衰期依次为5.5、6、15、19、5d。初
步鉴定4种菌分别属:节细菌(Arthrobactersp.)、芽胞杆菌(Bacillussp.)、不动杆菌(Acinetobactersp.)、不动
杆菌(Acinetobactersp.)。

| Abstract: | The four predominant bacteria that can degrade petroleum efficiently are obtained from the sludge in the
sewage of Yanan Oil Refinery by enriching,adapting, puri-fying and screening. Their degradation rate is studied with
shaking cultivation. The results indicate that petroleum hydrocarbons reduction of 4 strains and mixed strains were
90.8%, 88.9%, 57.8%, 49.8%, 91.2% respectively with initial concentration of 10000 mg/ L after 20 days. The
half-life of the petroleum hydrocarbons are 5.5 d, 6 d, 15 d, 19 d, 5 d in cultivation medium. Four petroleum-degraded
strains are identified as Arthrobacte sp., Bacillus sp., Acinetobacter sp., Acinetobacter sp. |
