| Abstract: | Objectives:The objective was according to the character of bacterium selecting a bacterium which could enhanced the proportion of the third MEOR.Methods:The methods was using the selective culture medium to select the bacterium,using the methods of identification to identify there character.Results:WTBZ]two bacteria were isolated with the methods of enrichment culture and plate cultivation from oil of Dqing Oil Field.The No.1 belonged to Pseudomonas,the No.1 belonged to Bacillus.By identified,both of two bacterium could produced some materials such as carboxylic acid,mix gas and biosurfactants,and the No.1" the degradation ratio of crude oil was 65.2%,the No.2' the degradation ratio of crude oil was 62.1%.Conclusion:Two bacteria were isolated from oil of Daqing Oil Field could degrade the stick of crude oil effectively. |
| Keywords: | microbial enhanced oil recovery crude oil bacterium selection biosurfactant |
