Section: Remediation and rehabilitation
The combined use of a consortium of microorganisms-destructors and sorbent in native and nanoscale form allows to ensure the rate of destruction of oil pollution at a higher level compared to the use of each component separately. Bentonite and nanobenthos not only adsorb hydrocarbons, and are a source of mineral nutrition for autochthonous microflora, improving the soil structure. Nanoantenna at least in 10 times the dose of making contributes to the efficiency of purification of polluted soil in comparison with bentonite in native form. Included in the consortium microorganisms-destructors (Achromobacter insolitus, Achromobacter xylosoxidans and Pseudomonas stutzeri) are actively integrated into the natural population, adapt and begin to effectively decompose hydrocarbons, using them as food and energy.
