Abstract
A diesel-degrading bacterium (strain IU5) isolated from oil-contaminated soil was characterized in this study. Fatty acid and 16s rDNA sequence analysis identified IU5 as a strain of Pseudomonas aeruginosa, and growth curve experiments identified the bacterium's optimum conditions as pH 7 and 30°C. P. aeruginosa IU5 degraded up to 60 of applied diesel (8500 mg/kg) over 13 days in a soil-slurry phase. In addition, this strain was able to grow on many other petroleum hydrocarbons as sole carbon sources, including crude oil, gasoline, benzene, toluene, xylene, and even PAHs such as naphthalene, phenanthrene and pyrene. Therefore, P. aeruginosa IU5 may be useful for bioremediation of soils and groundwater contaminated with a variety of hydrocarbons.
