Abstract
A halophilic bacterial consortium that degraded phenanthrene was developed from oil-contaminated saline soil containing 10% salinity. The biodegradation of phenanthrene occurred at 5%, 10%, and 15% salinity, whereas no biodegradation took place at 0.1% and 20% salinity. A 16S rRNA gene analysis showed that all sequences from the denaturing gradient gel electrophoresis profile were similar to those of halophilic bacteria. This is the first report of a halophilic bacterial consortium capable of degrading phenanthrene under hypersaline conditions.
