This study was carried out to determine the chemical composition, amino acid and fatty acid profile of D. armatus and S. ecornis, and to examine the effects of different cultivation mediums (BG11 and WC mediums) on the growth. The polyunsaturated fatty acid (PUFA) were found to be at maximum level both of algae species and were followed by monounsaturated fatty acids (MUFA) in S. ecornis and saturated fatty acids and MUFA in D. armatus. In both of algae species, gamma-linolenic acid (C18:3n6) was found to be at the maximum level, but no docosahexaenoic acid (DHA) was detected. Eicosapentaenoic acid (EPA) rates of S. ecornis and D. armatus were determined to be 2.31% and 6.47%, respectively. Total amount of free amino acids was found 89.25 g/100 g in D. armatus and 43.24 g/100 g in S. ecornis. Total amount of essential amino acids (Sigma EAA) was determined to be 32.83 g/100 g for D. armatus and 16.84 g/100 g for S. ecornis. The total amount of non-essential amino acids (Sigma NEAA) was determined to be 56.42 g/100 g for D. armatus and 26.40 g/100 g for S. ecornis. Microalgae is one of the important source of food supplements for human and animal nutrition.
