title: Isolation and characterization of a newly isolated polycyclic aromatic hydrocarbons-degrading Janibacter anophelis strain JY11.
abstract: The PAHs-degradation bacterium strain JY11 was newly isolated from the polluted soil in Jinan Oil Refinery Factory, Shandong Province of China. The isolate was identified as Janibacter anophelis with respect to its 16S rDNA sequence, DNA-DNA relatedness and fatty acid profiles, as well as various physiological characteristics. The strain was Gram-positive, non-motile, non-spore-forming, short rods in young culture, 0.8-1.0 microm in diameter and 1.3-1.6 microm long, and coccoid cells in the stationary phase of growth that are 1.0-1.2 microm in diameter and 1.3-1.5 microm long, occurred in pairs and sometimes in chains or in group, aerobic, oxidase-week positive, catalase-positive. J. anophelis strain JY11 can utilize naphthalene, phenanthrene, anthracene, pyrene, xylene, methanol, ethanol and salicylic acid as sole carbon source. The strain could remove 98.5% of phenanthrene, 82.1% of anthracene, and 97.7% of pyrene with an initial concentration of 500 ppm in five days without adding co-metabolism substrates and surfactants.
