Due to the growing demand for fuels and the consequent concern with the problems related to the burning of these products, the interest arises in developing new technologies linked to the use of natural resources to generate renewable energy1,2, replacing conventional sources. Based on this assumption, biomass is an excellent alternative for biofuel production.3 Microalgae have shown great advantages compared to traditional agricultural crops. Microalgae have a high production capacity of oil per unit area4; are adaptable crops, including using brackish or wastewater in their cultivation and which would be unsuitable for traditional agricultural crops, provided they have satisfactory heat and radiation conditions.5 In addition, microalgae have high atmospheric CO2 fixation capacity.6 In this context, an evaluation of the yield of lipids extracted from biomass is presented microalgae Scenedesmus sp. following various treatments (homogenization and physicochemical variations of the environment: such as temperature and/or pH), which allow the selection of a technological route for the extraction of lipids of interest, aiming the production of biodiesel.
