PAHs are toxic compounds with carcinogenic effects on humans that are released into the environment by incomplete combustion of fossil fuels. Three methods are commonly employed for PAHs pollutant removal: physical, chemical, and biological. From among these, the biological method which typically contains microbial processes and transforms pollutants to nontoxic or less toxic substances is the most innocuous and effective solution. In this study, attempts were initially made to enrich, isolate, and purify indigenous bacteria from PAHs polluted soil. In the second stage, the PCR method was exploited to identify the bacteria that had the capability of growth and reproduction in polluted conditions. It was found that the degrading bacteria are component species of gram negative bacilli determined as Shewanella, Pseudomonas, and Achromobacter. The results of the present study indicate that the bacteria have the best performance in PAHs removal from polluted environments.
