Microalgae can be used as a source of alternative food, animal feed, biofuel, fertilizer, cosmetics, nutraceuticals and for pharmaceutical purposes. The extraction of organic constituents from microalgae cultivated in the different nutrient compositions is influenced by microalgal growth rates, biomass yield and nutritional content in terms of lipid and fatty acid production. In this context, nutrient composition plays an important role in microalgae cultivation, and depletion and excessive sources of this nutrient might affect the quality of biomass. Investigation on the role of nitrogen and phosphorus, which are crucial for the growth of algae, has been addressed. However, there are challenges for enhancing nutrient utilization efficiently for large scale microalgae cultivation. Hence, this study aims to highlight the level of nitrogen and phosphorus required for microalgae cultivation and focuses on the benefits of nitrogen and phosphorus for increasing biomass productivity of microalgae for improved lipid and fatty acid quantities. Furthermore, the suitable extraction methods that can be used to utilize lipid and fatty acids from microalgae for biofuel have also been reviewed.
微藻可以用作替代食品、动物饲料、生物燃料、肥料、化妆品、营养保健品和药物的来源。从不同营养成分中培养的微藻中提取有机成分，受到微藻生长速度、生物量产量和营养成分（脂质和脂肪酸生产）的影响。在这种情况下，营养成分在微藻培养中起着重要作用，这种营养成分的消耗和过量来源可能会影响生物质的质量。已经研究了氮和磷对藻类生长的关键作用。然而，提高大规模微藻培养中营养物质利用效率存在挑战。因此，本研究旨在强调微藻培养所需的氮和磷水平，并侧重于氮和磷对提高微藻生物质生产力以增加脂质和脂肪酸数量的益处。此外，还回顾了可用于从微藻中提取脂质和脂肪酸以用于生物燃料的合适提取方法。
