  • PSEUDOMONAS AND USE THEREOF
    Publication number: 20240392235
    Abstract: Pseudomonas and a use thereof are provided. The preservation number of the Pseudomonas is CGMCC No. 22583. The growth temperature of the Pseudomonas is 37-45° C. Under a medium-high temperature oil reservoir condition, the Pseudomonas can be denatured from a non-viscosity fluid to a multifunctional oil-extraction bacterial solution having both surface activity and viscoelasticity, and also has the functions of expanding the swept volume and improving the oil washing efficiency. The recovery ratio is increased by more than 20% in a physical simulation experiment.
