Article:

Estima-se que 80 a 90% da água fornecida às refinarias de petróleo e plantas petroquímicas seja descartada como água residual. A biodegradação é um importante processo de biorremediação da água produzida. Neste trabalho, a microalga Chlorella vulgaris foi cultivada em meio contendo diferentes concentrações de água produzida, avaliando a sua potencialidade para aplicação em biocombustíveis através do perfil de ácidos graxos das biomassas. Foram realizadas 3 condições de cultivo (30%AP, 40%AP e 50%AP), sendo realizado a extração de lipídios, quantificação e identificação de ácidos graxos e cálculo teórico de biodiesel. O cultivo de C. vulgaris em meio contendo 40% de água produzida e 60% de meio BG-11 possibilitou o maior acúmulo de lipídios e ácidos graxos.

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.
