80 to 90% of the water supplied to oil refineries and petrochemical plants is estimated to be disposed of as wastewater. Biodegradation is an important process of bioremediation of produced water. In this work, Chlorella vulgaris was cultivated in medium containing different concentrations of produced water, evaluating its potentiality for application in biofuels through the fatty acid profile of biomass. Three cultivation conditions were performed (30% AP, 40% AP and 50% AP), lipid extraction, quantification and identification of fatty acids and theoretical calculation of biodiesel. The cultivation of C. vulgaris in medium containing 40% of produced water and 60% of BG-11 medium allowed the largest accumulation of lipids and fatty acids.
