Bacterial Surfactants for Purification of Oil Contaminated Soil


Bacterial surfactants-based biotechnology of purification of oil contaminated soil is an ecologically well-grounded technology for removal of petroleum contamination from soils and reduction of bioremediation period by using unique biological preparation based on safe surface-active substances produced by bacteria.

A special approach to bioremediation strategy depending on specific conditions of contaminated area and character of oil pollution provides guaranteed restoration of oil polluted soil in oil fields, refining and oil storing places.

Innovative Aspect and Main Advantages

  • This ecologically safe technology provides use of nontoxic, easily degraded biogenic origin surface-active substances – biosurfactants;
  • The unique association of hydrocarbon degrading and surfactant producing microorganisms from Culture Collection of the Institute of Microbiology of Azerbaijan National Academy of Sciences is being the main source of biosurfactant;
  • The surfactant preparation is capable of providing rapid and high efficient emulsification of oil and oil products which further can be easily consumed by microorganisms;
  • It is active during biodegradation of oil sludges - solid waste stored in sedimentation tanks where the concentration of ecologically dangerous elements including heavy metals exceeds maximum permissible concentration by 10 times;
  • It is cost-effective.

Areas of Application

This technology can be used for restoration of oil polluted landscapes including environmentally sensitive arid zones with high annual temperature and oil-sludge storages and torch platforms in oil-field areas. The technology is effective both for areas with long-term routine oil pollution and in cases of accidental spills.
