Spirulina platensis was cultivated in laboratory under controlled conditions in four different culture media, BG-11, modified BG-11, Zarrouḱs (ZM) and synthetic human urine (SHU). The effect of culturing media on chemical composition, amino acids content, fatty acids profile and minerals content were determined. The highest amount of protein (59.8%) was recorded when grown in BG-11. Whereas, modified BG-11 was the best medium in regard to both amino acids contents and maximum total lipid (8.13%). The most important unsaturated fatty acid γ-linolenic, was found at maximum percentage (4.7%) when grown in SHU medium. Whereas ZM was the best medium to obtain the highest percentage of arachidoic acid (17.63%).The highest percentage of ash in S. platensis was recorded when grown in ZM. Regarding to the minerals content, the maximumP, Ca, Mg, Zn and Cu (182.7, 155.8, 8.4, 5.1 and 5.5 mg/100g DW, respectively) were recorded in BG-11, while growing in ZM displayed the highest amount of K, Na and Fe (593.4, 766.7 and 39.9 mg/100g, respectively).
