Influence of Fe+2 on the biomass, pigments, and essential fatty acids of ‏Arthrospira platensis

Abstract The effects of different ferrous sulfate (FeSO 4 ) concentrations on the fatty acid profile blue-green alga Arthrospira platensis cultured in Zarrouk’s medium to produce biodiesel were studied. Different (0, 0.005, 0.01, 0.05, and 0.1 g/L) 0.01 g/L examined biochemical composition acids A. . Findings revealed that highest lowest yields 0 FeSO , respectively. It was also noticed an increase palmitic acid, oleic linoleic γ-linolenic docosahexaenoic when between 0.05 g/L, while these decreased at low concentration. Ferrous a concentration exhibited best following: growth rate shortest doubling time, chlorophyll-a, phycocyanin, allophycocyanin, phycobiliproteins, carotenoids. Thus, increasing has led individuals, which turn, resulted potential enhancement production from platensis.
