【 摘 要 】

The aim of this study was to investigate the potential of degradation of an autochthonous bacterial strain, isolated from petroleum derivatives contaminated soil samples against jet fuel hydrocarbons. The autochthonous bacterial strain was characterized as Nocardia sp. Evaluation of their degrading abilities was carried out by presumptive assays as redox indicator test and by observations of surface tension decreases in aqueous medium. Degradation of jet fuel hydrocarbons was evaluated by chromatographic methods. Experiments were performed in flasks at two biostimulation rates. A bacterial strain of Pseudomonas aeruginosa UFPEDA 39 was utilized as a reference microorganism. The bacterial strain, identified as Nocardia sp, demonstrate high ability to degrade jet fuel compounds as well as to produce surface active compounds when compared to the reference microrganism.
