Abstract:The biosurfactant-producing strains designated as DTYF-14, DTYF-15 and WXJY-13 isolated from soil samples can significantly reduce the surface tension and the interfacial tension of water / n-nonane. The whole broths of strain DTYF-14, DTYF-15 and WXJY-13, formulated with chemical surfactant HABS, not only reduced the amount of HABS but also widened the concentration range of NaOH needed for producing ultra-low interfacial tension between the reservoir water and the crude oil of Daqing oil field. | |||
