The linear alkyl benzene sulfonate is organic pollutants resulting from uses of detergents types. I have conducted several studies on the Mediterranean to monitor the concentrations of these pollutants, however, little is known about the fate of the
environment and the effect of environmental factors on the degradation these compounds.
In this research laboratory to conduct a study of the degradation of alkyl benzene sulfonate compounds under different conditions, during the period from September to November 2007 period cuddling continued for three months, and storage the samples in different conditions, (Laboratory conditions presence of light, laboratory conditions in isolation from the light at 25 C° and 15 C°) were identified in total concentration of LAS hydrological and specifications according to the following program:(0-1-3-5-7-14-21-30-45-60-90) day.
The results showed decrease total concentration of compounds LAS with the passage of time cuddling, compounds change specifications hydrological water by the biodegradation of the vital processes of photosynthesis taking place in aqueous media.
Proteus volgaris was isolated from costal sea water of Lattakia city port, as it is contaminated with petroleum compositions coming from marine transportations activities. The ability of this bacteria to degrade the petroleum alkanes was studied by
using different concentrations of petroleum as sole source of carbon and energy. The gas chromatography (GC) technique was used to measure the concentration of alkanes. Results showed that the isolated bacteria were able to degrade different alkanes chains. The ratio of biodegradation of C12, C16, C18 were 96.75%, 78.59%, 97.27% respectively, while the rate of biodegradation of the entire amount of alkanes was 77.14% in 10 mg/ml polluting concentration. The percentage of biodegradation at concentration 75 mg/ml of petroleum was 17.26%.
Therefore, the high ability of Proteus volgaris to degrade the long chains alkanes recommended it to be effective in the bioremediation process of the contaminated marine environments.
