Evaluation of green microalgae isolated from central and north coast of Sao Paulo as source of oil

Microalgae strains, newly isolated from freshwater in mangrove areas of Central and North Coasts Sao Paulo State (Brazil), were evaluated regarding total protein lipid content, fatty acids profile. The biochemical composition was compared with that observed strains obtained by UTEX Culture Collection (USA). Among seven identified green algae, Monoraphidium contortum (CCMA-UFSCar-701) presented the highest content (43.60%), close to Botryococcus braunii (UTEX-2441; 48.85%). Protein varied range 13.90~23.60%. Finally, most abundant palmitic acid (C16:0), oleic (C18:1), linoleic (C18:2), y-linolenic (C18:3).Chlorella vulgaris (CCMA- UFSCar-704) may be highlighted for its high (49%). On other hand, Elakatothrix sp UFSCar-702) Scenedesmus obliquus (UTEX-B2630) (41% 43%, respectively), which is preferable oils used as feedstock biodiesel.
