Potential hydrocarbon degrading bacteria were screened from the site artificially polluted with 20,000 ppm of diesel. Among the isolates, two strains, SJD2 and SJD4, showed higher activities to degrade diesel on the Bushnell-Hass broth medium containing 2% of diesel. 16S rDNA sequence analysis revealed that SJD2 and SJD4 were Bacillus fusifomis and B. cereus, respectively. Both strains were found to grow in a wide range of temperature between $20^{\circ}C-55^{\circ}C$, with the best at $30^{\circ}C-37^{\circ}C$. This is the first report, as far as we know, that B. fusifomis is capable of degrading diesel. We hope that a new isolate, B. fusifomis, will efficiently conduct bioremediation at the contaminated sites with petroleum hydrocarbons.
