Microalgae are rich in nutrients and biologically active substances such as proteins, carbohydrates, lipids, vitamins, pigments, phycobiliproteins, among others. The lipid composition of the microalgae , , and was screened for the first time. The proposed method for purifying the lipid complex isolated from microalgae's biomass involved dissolving the lipid-pigment complex in -hexane for 4 h and stirring at 500 rpm. We found that the largest number of neutral lipids is contained in the biomass of microalgae , fatty acids, polar lipids (glycerophospholipids), and unsaponifiable substances-in the biomass of microalgae , chlorophyll, and other impurities-in the biomass of microalgae . The developed method of purification of the fatty acid composition of the microalgae lipid complex confirmed the content of fatty acids in microalgae, which are of interest for practical use in the production of biologically active components. We also determined the potential of its use in the development of affordable technology for processing microalgae into valuable food and feed additives.
微藻富含蛋白质、碳水化合物、脂类、维生素、色素、藻胆蛋白等营养物质和生物活性物质。首次对微藻的脂类成分进行了筛选。从微藻生物质中分离脂类复合物的纯化方法包括将脂-色素复合物在正己烷中溶解 4 小时，并在 500rpm 下搅拌。我们发现，微藻生物质中含有最多的中性脂类，脂肪酸、极性脂类（甘油磷脂）和不可皂化物——微藻生物质中的叶绿素和其他杂质——微藻生物质中的类胡萝卜素。微藻脂类复合物脂肪酸成分的纯化方法得到了证实，其中含有对实际生产生物活性成分有价值的脂肪酸。我们还确定了其在开发经济实惠的微藻加工技术，以生产有价值的食品和饲料添加剂方面的应用潜力。
