چکیده

The purpose of this study was to investigate the growth and phenanthrene-degrading abilities of the halophilic bacteria consortium in different temperature. The bacterial consortium was isolated from saline and sodic soils contaminated with waste crude oil of Sarajeh Qom. The effect of different temperatures (15, 20, 30, 37, 45 and 54 °C) was investigated on the bacterial consortium growth and boidegradation of phenanthrene by this consortium in 10 days of experiment. The results showed that the bacterial consortium had the ability to grow on a wide range of temperature 15 to 54°C, but the optimal growth was observed at 37°C. This halophilic bacterial consortium was able to break down phenanthrene in the temperature range of 20 to 45°C, and the highest phenanthrene degradation (87%) was obtained at temperature of 37°C at the end of 10 days of experiment, which is consistent with bacterial growth.
