S. 22.Polycyclic aromatic hydrocarbons (PAHs) are persistent environmental pollutants characterized by high toxicity and low biodegradability [1]. In this study, bacterial strains capable of utilizing PAHs [2,3] were isolated from various extreme environmental habitats. The isolates were cultivated in mineral media supplemented with selected PAHs (specifically fluorene and phenantrene) as the sole carbon source and exposed to a range of concentrations to determine the maximum levels that the bacteria were able to utilize. The degradation efficiency was assessed by monitoring the residual concentrations of the target compounds using high-performance liquid chromatography with diode array and fluorescence detection (HPLC-DAD/FLD). The results revealed that several bacterial strains exhibited a remarkable ability to degrade specific PAHs even at elevated concentrations, highlighting their potential application in bioremediation of contaminated environments.enCC BY-NC-SA Creative Commons Attribution-NonCommercial-ShareAlike 4.0.
