Abstract: An investigation was conducted with a super heavy oil sample as sole carbon source to select highly efficient hydrocarbon-degrading strains among isolates from oil production water and analyze their degradation properties for oil four components and total hydrocarbon components.The results showed that:Strain H11 and W14,which belong to Pseudomonas aeruginosa based on 16 SrRNA gene sequence analysis,could emulsify super heavy oil thoroughly;the relative contents of aliphatic hydrocarbons were reduced by 20% after incubation with these two strains;furthermore,the two strains could degrade long chain hydrocarbons with C26 and C28as the longest ones,respectively.These data suggested that strain H11 and W14could be reliable resources to emulsify and degrading heavy oil and hydrocarbons in oil-and farm chemical-contaminated environments.
