Abstract:
Many algae produce large amounts of oil that can be converted to biodiesel. To study the lipid production, Chlorella vulgaris, Scenedesmus obliqus and Spirulina platensis were selected. Samplings from different regions were done and cultivated in suitable condition. Based on results, the lowest amount of saturated fatty acids was observed in the Chlorella vulgaris (21. 79%). Lauric acid (C12:0), Meristic acid (C14:0), Penta-dicyclic acid (C15:0), Palmitic acid (C16:0) and Stearic acid (C18:0) were observed in all species in different amount. The greatest amount of unsaturated fatty acid was observed in Chlorella vulgaris. The diversity of fatty acids were different among species. Most of the diversity of fatty acids were observed in Scenedesmus obliqus with 22 fatty acids while that was 12 and 10 in Chlorella vulgaris and Spirulina platensis respectively. The highest amount of EPA and DHA saturated fatty acids were observed in Scenedesmus obliques. The greatest amount of unsaturated fatty acids belongs to the Linolenic acid (C18:3). The greatest amount of 2-bands unsaturated fatty acid were observed in Spirulina platensis with 18. 6%. The greatest amount of 3-bands unsaturated fatty acid were observed in Chlorella vulgaris was measured at 48. 53%. 4-bands unsaturated fatty acids were observed only in Scenedesmus obliques. Most of fatty acids composition in studied microalgae were unsaturated fatty acids types.
