摘要
为对比勿色杆属菌种(Achromobater sp)SLTHX114株和黄色假单胞菌(Pseudomonas flavescens)SLTHX214株对原油降解特征的差异性,在40℃恒温有氧实验室条件下,使用两株原油降解菌对塔里木油田原油进行了生物降解模拟实验,分析了生物降解气组分、生物降解原油的族组分及生物标志化合物变化特征。实验结果表明,革兰氏阴性SLTHX214株对原油降解能力强于革兰氏阳性SLTHX114株,SLTHX114株对原油中的饱和烃具有明显的降解作用,而SLTHX214株更倾向于降解原油中的芳烃。对土壤石油污染修复和菌种选择具有一定的指示意义。
The characteristics of Achromobatersp(SLTHX114)and Pseudomonas flavescens(SLTHX214)on crude oil biodegradation were studied.The biodegradation simulation experiments of the crude oil from Tarim Oilfield were carried out at the constant temperature of40℃under the aerobic laboratory conditions.The biodegraded gas components,the crude oil components and biomarkers compounds were analyzed.The experimental results showed that the efficiency of crude oil degradation of G-strain SLTHX214 is higher than G+strain SLTHX114.Strain SLTHX114 prefers to degrade the saturated hydrocarbons of crude oil during the oil biodegradation process,while the strain SLTHX214 tend to degrade aromatic hydrocarbons.Results from this study have certain significant for the soil oil pollution remediation and strain selection.
