In the current study, the PL7 strain was isolated from soil and identified as Raoultella planticola based on its physiological characteristics and 16S rDNA sequence. By the 10th day, the PL7 strain degraded 52.0% of the pyrene (PYR) content and 50.8% of the benzo[a] pyrene (BaP) content in 20 mg L-1 PYR and 10 mg L-1 BaP in the liquid matrix. The half-life of PYR and BaP by PL7 degradation was 8.59 and 9.46 days, respectively. At pH 8.0, the degradation rates of PYR and BaP by PL7 were significantly higher at 30 degrees C than at 20 and 40 degrees C. The degradation ability of PL7 differed in red soil, paddy soil and fluvo-aquic soil; red soil produced the fastest degradation rates. The half-life of PYR and BaP by PL7 degradation in red soil was 21.7 and 11.9 days, respectively; however, without PL7 the half-life of PYR in red soil was 91.2 days. This study demonstrated the significant potential of the PL7 strain for bioremediation applications in the liquid matrix and soil contaminated by PAHs.
