| 摘 要： | The solubilization and degradation of polycyclic aromatic hydrocarbons （PAHs） in soil was amending by many microorganisms. One of these microorganisms is Bacteria, which were isolated from different contaminated areas at Kafer El Zyat City, Gharbia governorate, Egypt. Wastes samples were collected and bacterial isolation was carried out using enriched media technique. More than 78 isolates were obtained and the degradation capability was examined for all of them. Fingerprinting was carried out for all the isolates using REP-PCR and the obtained results grouped them into 10 groups. Two bacterial strains from the isolated bacteria were showed high degradation talent and specificity for the type of the polyaromatic hydrocarbons （naphthalene or phenol）. Pseudomonas putida （DQ399838） and Flavobacterium sp. （DQ398100） were identified and their degradation capacity was examined using real time method. Strain P. putida showed degradation rate for naphthalene reached to 50% after 20 hours from inoculation. However, Flavobacterium sp. reached 50% rate of degradation after 17 hours from inoculation time. Whenever, the soil degradation rate can be enhanced by adding these adapted bacteria to the soil and amendment of these bacteria which will help in bioremediation technology.
