R5.4 show that thesestrains are active degraders of petroleum oil hydrocarbons, tolerate high concentrations of thesubstrate and have a high capability for degradation of hydrocarbons. Petroleum oil was degradedin the range from 60 to 90% after the culture was carried out for 9 days. The activity ofdehydrogenases was related to the concentration of the substrate. The gas chromatographyanalysis of residual hydrocarbons in the medium after 9 days of cultivation proved that themain identified petroleum oil components had been metabolized with the yield from 69 to 100%.Apart from the compounds originally present in crude oil no new by\-products were detected inthe final medium. The accumulation of shorter chain length hydrocarbons and various newby\-products occurred in the case of another tested bacterial strain, designated “B\"."]
