A novel PAHs (polycyclic aromatic hydrocarbons)-degrading strain, TAYx3 was isolated from mineral oil and heavy metal contaminated soil. Strain identification and characterization showed that TAYx3 wasYarrowia lipolytica.Tests forYarrowia lipolyticaTAYx3 growth on different substances are also described. The strain could use all PAHs tasted as sole carbon source, and showed synergistic interaction with humic acid (HA). With the existence of HA, the degradation rate of TAYx3 was naphthalene 90.7%, phenanthrene91.0%, fluoranthene74.7%, pyrene 86.9%, benzanthracene 84.7%, benzopyrene 74.7%, respectively.
