摘要

摘要本研究分析了大庆油田脱水原油中微生物群落结构、微生物及原油降解活性。结果表明，脱水原油中存在多种微生物细胞，并筛选出具有油乳化和油分散活性的微生物群落。群落分析表明，随着培养时间的延长，群落中微生物的种类和比例发生了变化。从原油培养体系中分离纯化了166株细菌，其中具有油分散或油乳化活性的细菌占13.1%。结果表明:大庆油藏中存在具有油乳化和油分散活性的微生物群落，条件恶劣和营养缺乏导致群落密度较小，油降解菌所占比例较高。

CLC Q938.15 : X74Microorganisms and Their Oil-degrading Activities in Dehydrated Crude Oil: CLC Q938.15 : X74Microorganisms and Their Oil-degrading Activities in Dehydrated Crude Oil

Abstract This study analyzed the microbial community structure, microorganisms and the oil-degrading activities in the dehydrated crude oil from Daqing Oil ﬁ eld. The results showed the existence of many microbial cells in the dehydrated crude oil, and screened a microbial community with oil-emulsifying and oil-dispersing activity. Community analysis showed that the types and rations of the microorganisms in the community changed with incubation time. All together 166 bacteria were isolated and puri ﬁ ed from the crude oil culture system, up to 13.1% of the tested strains having oil-dispersing or oil-emulsifying activities. The results showed that there are microbial communities with oil emulsifying and oil dispersing activities in Daqing oil reservoir, that the harsh conditions and the lack of nutrition leads to smaller community density, and that the oil degrading strains occupy a high proportion.

期刊介绍： The “Chinese Journal of Applied and Environmental Biology” is a national scientific and technological journal published both at home and abroad. It was started in 1995 and became bimonthly in 1999, and now it is a core journal for applied and environmental biology in China. It aims to introduce and exchange the new achievements, new technologies, new methods and new progresses made from the research fields of biology and its related disciplines both in China and abroad; enhance scientific and technological research serving for the development and construction of national economy, and improvement of people’s living standards.
