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.
