pdf Cleaning oil-contaminated soil by Psedomonas bacteria - basis of biological products NAFTOKS 12-R and NAFTOKS 48-U
The comparative characteristics of two newly created biologics NAFTOKS 12-R (Pseudomonas aeruginosa) and NAFTOKS 48-U (Pseudomonas citronelollis) on the effectiveness of cleaning soil from diesel fuel and oil in the laboratory are presented. For 7 months of experiments diesel fuel oxidized by 85.5-85.8% of initial content in the soil (? 2% wt.). Oil fractions in its content oxidized by 91.6 and 92.3%, benzene resins - 41.0 and 27.7%, alcohol-benzene resins - 39.8 and 37.5%, asphaltenes - 44.3 and 23.8% of the initial content. Methane-naphthenic hydrocarbons decreased by 92.0 and 92.3%, aromatic hydrocarbons - by 84.3-100% and 89.3-100% of the initial content, respectively, by adding NAFTOKS 12-R and NAFTOKS 48-U biologics in oil-contaminated soil. Biooxidation of oil contamination accompanied by formation of intermediate oxidation products. The fundamental principles of innovative technology of cleaning oil-contaminated soils using NAFTOKS biologics are discussed.

Keywords: oil-contaminated soil, bioremediation, NAFTOKS biologics, cleaning efficiency of soil, soil treatment technology.
