Soil in Daqing oil field was collected which had been contaminated with crude oil for more than ten years. The bacteria in the soil were cultured in the enrichment medium containing crude oil and mineral salts.The strains which could display Blood-plate hemolysis were picked out as the target strains with possibility to create bio surfactant. Then by the same way, the target strains were purified for more than three times and named H1137-2 which also was identified to Stenotrophomous maltophilia by using 16S rDNA sequence To acquaint the optimal growth condition of Stenotrophomous maltophilia H1137-2, an orthogonal experiment (4 × 3) was performed. The strains increased very fast with Urea as the optimizing nitrogen source. Mn²⁺ could prompt the strain´s growth, but not Fe²⁺. The strain could also lower the surface tension of its nutrient fluid. It has been concluded that Stenotrophomnas maltophilia H1137-2 can live on crude oil as the sole carbon source and has the potential to produce biosuefactants.
