| خلاصه مقاله | One of the major methods to reduce various pollutants is applying biologic method which is known as bioremediation. In this study we have tried to analyze the existence of naphthalene - degradation bacteria phenotypically and genotypically in Qurugol Lake. For this aim samples were taken from the locations of the lake which were the most polluted. These samples were incubated in a specific medium where naphthalene, was the only carbonic source of energy for providing the PAHs energy. The single colonies were isolated. Considering the fact that the decomposing bacteria of PAHs compounds were isolated, it became obvious that part of polluting process is done by these bacteria. The significant bacteria in this case are bacillus sp. and closely related type strains include B. pumilus (99.9%) Which are capable of decomposing PAHs efficiently in 5% salt concentrations and Shewanella sp. and closely related type strains include Sh. Xiamenensis (99.1%) Which are capable of decomposing PAHs efficiently in 1/5% salt concentrations. On the basis of phenotypic, and phylogenetic results, it is recommended that isolated S7d1M represents a novel strain of the species Sh. xiamenensis and The GenBank/EMBL accession number for the 16S rRNA gene sequences of strain S7d1M is GQ988720. |
