Isolation, characterization of Rhodococcus sp. P14 capable of degrading high-molecular-weight polycyclic aromatic hydrocarbons and aliphatic hydrocarbons

► Degradation capability of Rhodococcus sp. P14 to alkanes and PAHs (Phe, Pyr, and BaP). ► Floating activity of strain P14 showed in mineral oil-supplemented liquid medium. ► Changes of fatty acid composition of strain P14 grown in different carbon sources. ► Potential use of strain P14 in bioremediation of oil spills in the environment.
