Over the last decade, the use of microalgae for its high quality nutritional raw material and its ability to produce high amounts of lipids, proteins and different energy forms has become a challenge worldwide. The characterization of  the biochemical profile of a green microalgae Chlorella sp which was isolated from a Tunisian fresh water lagoon showed that this microalga accumulated 18% of lipid content (19% FA ω 3: 15% of C18:3 ω3, 3% EPA and 0.69% DPA) and a high protein content reaching up to 60%. of dry weight. Moderately producer of natural antioxidant, Chlorella sp. accumulates 3.7 mg AGE/ g DW and an inhibition concentration (IC 50) of 595µg/ ml. Finally, the anaerobic digestion of this microalgae provided 12.56% of CH4 biogas.

Keywords: Chlorella sp, oil, fatty acids, antioxydant, proteins, biogas
