ABSTRACT

The article deals with biological degradation of oil sludge located in Lužice, South
Moravia, Czech Republic. Bacteria strains Pseudomonas putida, Rhodococcus sp. and
mixed culture of these strains were used in the biodegradation process. The experiment
lasted for 35 days at 25°C. Changing values of polycyclic aromatic hydrocarbons
(PAHs), polychlorinated biphenyls (PCBs) and C10 – C40 hydrocarbons detected in
liquid mixture of petroleum sludge and bacteria medium were observed. The results
show that biodegradation of these organic contaminants originated from oil sludge was
successful. The highest degradation efficiency was approximately 76% (PAHs), 73%
(PCBs) and 78% (C10 – C40) using mixed culture.

Keywords: biodegradation, C10 – C40 hydrocarbons, polycyclic aromatic hydrocarbons,
