【 摘 要 】

The aim of this work was to investigate the potential of the diesel oil degrading yeasts to use them in bioremediation of areas contaminated by this pollutant. The cultures, identified as Rhodotorula aurantiaca UFPEDA 845 and Candida ernobii UFPEDA 862, were selected at the initial stage. In the course of the biodegradation assays, C. ernobii degraded tetradecane, 5 methyl-octane and octadecane completely and decane (60.8%) and nonane (21.4%) partially whilst R. aurantiaca presented degradation percentages of 93% for decane, 38.4% for nonane and 22.9% for dodecane.
