Biosurfactants are surface-active agents produced by most microorganisms. These compounds have various applications in several industries especially in the oil industry and bioremediation of oil contaminations. In this study among 22 isolated yeast strains, G-13 was selected as the best biosurfactant producing isolate by reducing the surface tension to 26 mN/m and creating a clear zone with 13.1 cm diameter. Molecular identification revealed that G-13 had 100% similarity to Rhodotrula sp. and deposited by accession number UTMC 5046 in the University of Tehran Microorganism Collection. Emulsification index (EI1 and EI24) of the Rhodotrula sp. UTMC 5046 was determined 100% for toluene and diesel. According to the results, Rhodotrula sp. has a high potential in biosurfactant production and emulsification of hydrophobic compounds so it can be used in bioremediation of oil contamination.
