Production of unsaturated fatty acids (omega 3,6,7,9) from algae Lyngbya and Oedogonium under the influence of nitrogen and phosphorus

Microalgae have a lot of promise for making nutritious food and feed additives. These photosynthetic show promise for the longterm production of lipids due to their capacity to transform carbon into high-value chemicals and their ability to be grown on a vast scale without interfering with crop cultivation. Particularly, microalgae serve as a substitute source of unsaturated fatty acids (UFAs), whose consumption is linked to a number of advantages for both human and animal health. The generation of PUFAs in microalgae has been improved in recent years through the investigation of several methods. Two algae were isolated from the Gharaf river in Thi-Qar (Oedogonium, Lyngbya). The study was conducted on the effect of different concentrations of nitrogen and phosphorus for each of the unsaturated fatty acids of the two algae. Nitrogen concentrations were (5,10,20) and for phosphorus (1,5,10). These (UFAs) are affected when these nutrients are added to the culture medium, and as the concentration of these nutrients increases, we notice a decrease in the proportions of these unsaturated fatty acids (Octadecatrienoic acid, omega 6, Oleic acid omega 9, Eicosapentanoic acid omega 3, Docosatetraenoic acid omega 3) in Lyngbya and with absence OA, Docosatetraenoic acid and presence (vaccenic acid, omega 7) in Oedogonium.
