In addition to the fatty components present in the lipid extract, other components may be included, such as: carotenoids, pigments and sterols. The microalgae studied in this work, Scenedesmus sp. and Desmodesmus sp., were subjected to the same growth conditions and evaluated for lipid content, quantification and diversity of lipid components as well as its fatty acid profile. For lipid determination two extraction methods were compared: the J: Schmid-Bondzynski-Ratzlaff and Bligh & Dyer method. For Desmodesmus sp. 5.43% ¡À 0.41% and 9.18% ¡À 0.33% of lipids were obtained on an ash-free dry weight basis and for Scenedesmus sp. 12.46% ¡À 0.38% and 8.16% ¡À 0.42% of lipids were obtained on an ash-free dry weight basis using for both methods J: Schmid-Bondzynski-Ratzlaff and Bligh & Dyer, respectively. For the identification of the main lipid components present in the extracts, the Thin layer chromatography (TLC) technique was used.
