Abstract
In a weakly or moderately polluted with oil (0.3-1.0%) the total number of soil microorganisms, including hydrocarbon-oxidizing, you can improve cultural practices (tillage, irrigation, fertilization) without making out of hydrocarbon-oxidizing microorganisms (HOM). In the arid zone is more expedient to begin bioremediation of oil-contaminated areas of work for the fall, to use autumn and spring soil moisture for mineralization activity of microorganisms.
Highlights
Environmental protection from oil pollution gains special sharpness due to the lack of cheap methods of cleaning
The comparative analysis of a condition of spontaneous microflora on the control and regularly polluted by various fractions oil products of soil showed that the number of the main groups heterotrophes makes 58%, the spore-forming microorganisms – 68% of the number of microorganisms on control sites that is explained by toxic effect of oil products on activity of miсrorganisms
When determining a share the hydrocarbon - oxidizing microorganisms (HOM) in the general structure of microflora of the soil it is established that about 30% of microorganisms are capable to use oil hydrocarbons as the only source of carbon and energy
Summary
Environmental protection from oil pollution gains special sharpness due to the lack of cheap methods of cleaning. Among them: a stimulation of indigenous microflora growth, by means of arranging of optimal conditions for its development (Wyszkowska J and Kucharski J, 2000, Panicker G et al, 2002) and an introduction or augmentation of active hydrocarbon-oxidizing microorganism cultures in the soil or water bodies together with a number of biogenic elements in the form of biopreparations (Dzongo-Gadet M. et al, 2005, Ayotamuno, 2009, Keil et al, 2011). These methods are advantageous due to high efficiency and mild influence, which does not upset the balance of soil ecosystem
