Biodegradation of Oil Hydrocarbons by Soil Microflora Activated with Photoluminescence Films

Stimulating effect of polyethylene photoluminescence films on the growth of autochthonous microflora population in oil-polluted soils has been determined under the laboratory conditions, where oil concentration in the soil was 50 g/kg. The increase in number of basic groups of microflora was accompa...

description Stimulating effect of polyethylene photoluminescence films on the growth of autochthonous microflora population in oil-polluted soils has been determined under the laboratory conditions, where oil concentration in the soil was 50 g/kg. The increase in number of basic groups of microflora was accompanied with the increased activity of the enzymes, which catalyzed oxidizing processes. At the end of the experiment, on the 45-th day, oil content decreased to 15 g/kg. The analysis of the residual hydrocarbons by IR-spectroscopy has revealed absorption bands in the regions of 1710 cm–1 and 1600 cm–1. At the same time spectral coefficients С1, С2, А1 and А2 increased 1.5-3 times, while С3 and А3 decreased 1.5-2.5 times indicating oxidation processes of oil hydrocarbons. Chromatographic analysis proved the intensity of hydrocarbon biodegradation. Hydrocarbons С11-С14 completely eliminated in the test samples and the concentration of hydrocarbons with a high molecular weight decreased by 70-80%. At the same time hydrocarbon biodegradation index, determined as the ratio of the sum of isoprenoids (pristine + phytane) to the sum of n-alkanes (С17 + С18), increased 5-6 times due to the use of photoluminescence films.
