从土样中初步筛选及其性质实验研究

Selecting Bacteria from the Soil and the Character of Physics and Chemistry

目的:希望筛选出能够产酸,产气、产生生物表面活性剂的微生物。方法:根据目标菌株的特性进行筛选。结果:得到8株菌均能降低原油黏度,降黏率最高能达到75.5%。结论:筛选的八株菌株确实具有降低原油黏度的作用,能够提高三次采油的采收率。

Objective： We hoped to sclect a bacterium which could produced some carboxylic acid and mix gas and biosurfactants and degraded the stick of crude oil effectively. Methods： According to the character of the bacterium, according to the character of the bacterim could produced some carboxylic acid and mix gas and biosurfactants. Results： Eight bacteria were isolated with the methods of enrichment culture and plate cultivation from oil of Daqing oil Field. the highest degradation ratio of crude oil reached to 75.5 %. Conclusion ： Eight bacteria were isolated from oil of Daqing oil field could degrade the stick of crude oil effectively.
