The current study is an attempt to high light the possibility of stimulating the amount of total lipids of three species of local algae, Prymnesium parvum, Botryococcus braunii and Chlorella vulgaris were isolated, for the purpose of studying its contents of lipids and their potential is stimulated to produce lipids. In the present study, algae samples were collected from various areas of Najaf city, including, Low sea of Najaf, Shat AL- Kufa and AL- Abbasiyah regions. Identified and isolated several species of algae used in extracting some fatty compounds studies of which: Gloeocapsa sp., Prymnesium parvum, S. Chlorella, Botryococcus braunii, Cylindrocapsa, Spirulina sp., Chlorella sp., Oscillotoria sp., Strigeoclonium sp., Neochloris sp., Microcystis, Chlorella pyrenoidosa, Scenedesmus dimorphus, Prymnesium parvum attended a pure culture of the Prymnesium parvum, Botryococcus braunii, Chlorella vulgaris and three cultures were selected for growth and culture, BG11, Chu13, Chu10 under standard conditions (2 ± 25°C and 3000 l Lux and 16:8 light : dark as light system). The experiments included the study of the effect of the quality of the medium on fats. The second factor of agriculture medium with a number of transactions remove the nitrogen from the medium, add NaCl at a concentration of 2g/L. The results of the present study showed that the highest total lipids was recorded when nitrogen was removed from the Chu13 medium for algae Prymnesium parvum. was 319.8mg/g dry weight and the lowest total fat in the Chlorella vulgaris in the medium of control Chu10 (88.1). Also recorded the highest percentage of total lipids recorded at the genus Prymnesium parvum in the medium BG11 after removal of nitrogen and reached 80.48%. The lowest percentage of total lipids the was recorded at Chlorella vulgaris genus in the medium of control Chu10 and reached 31.49%.
