The importance of crucial nutrient factors like Phosphate (P) and their limited availability leads to variable fluctuations in fatty acid and phospholipid synthesis in the green alga. These fatty acids and phospholipids are an imperative byproduct of alga which used in biofuel production. The production of phospholipids in alga might be naturally enhanced by the optimized supplied by specific essential nutrient like Phosphate. In this study, green alga Chlamydomonas reinhardtii was cultivated in phosphate stress condition to obtain maximum phospholipids. In the stress condition, the organism exhibited variable changes in chlorophyll, fatty acid, and phospholipid compositions. These parameters analyzed by biomass, X-ray, GC, and TLC. Remarkably, saturated fatty acids, monounsaturated, and di-unsaturated fatty acids amounts, increases, while polyunsaturated fatty acids to decrease markedly. The maximum fatty acid content observed at 0.4 mgl-1 P content in growing media. A broad peak area of 56% of hexadecanoic acid (C 16:0) and followed by 28.8% linolenic (C18:3) was observed in GC analysis. These results indicate the essential fatty acid accumulation maximized at particular phosphate concentration in growing media. This necessary and essential fatty acid production from green algae in a sustainable manner is an inexpensive and excellent way for commercialization and biofuel production.

莱茵衣藻(Chlamydomonas reinhardtii)在磷限制下合成脂肪酸。

关键营养因子(例如磷酸盐(P))的重要性及其有限的利用率会导致绿藻中脂肪酸和磷脂合成的波动。这些脂肪酸和磷脂是用于生物燃料生产的藻类必不可少的副产物。通过特定必需营养素(如磷酸盐)的优化供应,藻类中的磷脂生产可能会自然增加。在这项研究中,在磷酸盐胁迫条件下培养了绿藻莱茵衣藻(Chlamydomonas reinhardtii)以获得最大的磷脂。在胁迫条件下,生物体的叶绿素,脂肪酸和磷脂组成表现出可变的变化。这些参数通过生物量,X射线,GC和TLC分析。值得注意的是,单不饱和和二不饱和脂肪酸的饱和脂肪酸含量会增加,而多不饱和脂肪酸明显减少。在生长培养基中,最大脂肪酸含量为0.4 mg-1P。在GC分析中观察到56%的十六烷酸(C 16:0)和28.8%的亚麻酸(C18:3)的宽峰面积。这些结果表明,在特定的磷酸盐浓度下,生长培养基中必需脂肪酸的积累达到最大。以可持续的方式从绿藻生产这种必需的必需脂肪酸是用于商业化和生物燃料生产的廉价且极好的方法。这些结果表明,在特定的磷酸盐浓度下,生长培养基中必需脂肪酸的积累达到最大。以可持续的方式从绿藻生产这种必需的必需脂肪酸是用于商业化和生物燃料生产的廉价且极好的方法。这些结果表明,在特定的磷酸盐浓度下,生长培养基中必需脂肪酸的积累达到最大。以可持续的方式从绿藻生产这种必需的必需脂肪酸是用于商业化和生物燃料生产的廉价且极好的方法。
