Degradation of phenol and polycyclic aromatics hydrocarbons (PAHs) presented in artificially contaminated and/or real soil collected from a contaminated site of former coke plant by free cells of Candida tropicalis was studied in batch cultures and at the ratio of liquid culture media:soil = 2:1 with the initial concentration of phenol 560 mg/kg and 152 mg/kg (real soil), respectively. The results confirmed that aerobic biodegradation of phenolic compounds is a viable method for their destruction both linked on solid matrix of soil and in aqueous liquids extracted from soil. Based on the fact, that in the case of mixed contamination PAHs are mostly resistant to biodegradation, mixed strains of Candida tropicalis and fungus Phanerochaete chrysosporium were simultaneously applied on bioremediation of aqueous slurry of contaminated soil with high efficiency. This mixture of microorganisms proved to be a potent tool for effective biotreatment of contaminated site of former coke plants.
