Abstract: 

Using microorganisms among the suggested remedies for oil pollution problembs and its destructive effects is a way which is used as the title of bioremediation in most developed countries. Using bioremediation to remove pollution from polluted areas is limited by means of some bioenvironmental parameters. Nutrients are one of these elements. In this study four types of bacteria were isolated from the Boushehr Soils. The mentioned kinds were nominated as Pseudomonas stutzeri, Chryseo bacterium Sp, Acinetobacter Johnsonii, Pseudomonas aeruginosa. These bacteria were studied from the aspect of their ability to degrade phenanthrene in different P concentrations and in different periods of time. The results showed that the best phosphorus concentration in biodegradation of phenanthrene equals to 2 mgr/lit, and the best performances is related to bacterial pseudomonas aeruginosa, and the best of time in biodegradation phenanthrene is 144 hours.
