In the present study we have determined the effect of petrol oil on Spirulina platensis growth rate. It is exposed to different concentration of petrol oil to see the effect of petrol on the protein, carbohydrate and growth rate of Spirulina platensis. It involved 2,5,10 and 20 ml of petro oil in the media after which the survival and the growth of the S. platensis were evaluated. Although the percentage of protein and carbohydrate decreased as the quantity of the petrol oil added to the media comparison to the control samples. The results obtained in this study showed that spillage of mixture of gasoline poses threats to the survival and development of algae and plants.
