ABSTRACT

The article is focused on biological degradation of selected polycyclic aromatic hydrocarbons occurring in oil sludge and oil contaminated soils, situated at estates belonging to company dealing with oil extraction located in Lužice, Czech Republic.
Pseudomonas putida, Rhodococcus sp. and a mixed culture of these strains are used for the degradation of oil sludge in co-action of the original microbial consortia.
The experiments were carried out in 35 days at 25 °C. The changing values of benzo[g,h,i]perylene, benzo[a]pyrene and other observed polycyclic aromatic hydrocarbons proved a degradation potential of all selected bacterial strains. Comparing the experiment results, the mixed culture is discovered to be less effective than the individual bacterial strains.
In comparison with results of other conducted experiments, the mixed culture is discovered to be less effective than the individual bacterial strains.

Keywords: benzo[a]pyrene, benzo[g,h,i]perylene, biodegradation, oil sludge, Pseudomonas, Rhodococcus
