Abstract

The effects of incrementally adding one or more of the nutritional materials on the bio degrading activity of the Sporosarcina ureae were investigated. The materials used and their rates were: Peptone (0.7%), Yeast (0.7%), Ureae (0.14%), Casein (0.7%), Fat Free Milk Powder (0.7%), Fish Extract (0.7%), Acidic Potassium Phosphate (0.14%), Sea Algal Extract (1.0%) and Sea Algal Powder (1 .0%). Among these, Peptone was the most efficient: it increased the bacterial bio degrading activity of the oil Polluted Gulf water to 92.0%. It was also revealed that, in comparison with the control treatment, the addition of a mixture of algal powder, phosphate, fish Extract and fat-free milk powder to the Gulf water-containing oil, caused a tremendous increased in oil biodegradation. Oil biodegradation in presence of the bacteria reached 88.5%, and in the absence of the bacteria reached 80.4%.
