Bioremediation of oil-polluted coastal soils of the Caspian Sea with active oil-oxidizing associations
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 10
Abstract
Model studies on the purification of oil-polluted coastal soil by bacterial and bacterial-yeast associations were carried out. It is established that when they are introduced, changes in the composition of the microbiocenosis occur. In this case, the number of heterotrophic bacteria and hydrocarbon-oxidizing microorganisms is significantly increased. During the entire experiment, the bacterial-yeast association showed the greatest activity. Under its impact, oil utilization amounted to 62.3-84.0%. In this case, the use of manure with ammonium nitrate was more effective than the introduction of urea. Experimental data showed that more intensive destruction of oil occurs with the introduction of preparations in an amount of 1-2 g per 300 g of contaminated soil.
