Gas Chromatographic Investigation of Oil Biodegradation Degree

The research of the degree of oil biodegradation by gas chromatography and individual classes of hydrocarbons by various strains of hydrocarbon-oxidizing microorganisms isolated from indigenous microflora of oil fields was carried out. It has been shown that some of the investigated strains of hydrocarbon-oxidizing microorganisms are 100% capable to biotransform naphthenes and olefins, showing high activity in the destruction of paraffins and isoparaffins. There are no signs of biodegradation of aromatic compounds due to the large duration of the process. All investigated strains of hydrocarbon-oxidizing microorganisms are largely able to reduce the total number of individual components of oil. The obtained data can be used to develop new biologics of the purpose.
