Lipid content and composition of fatty acids with 6-25 carbon atoms were studied on strains of the 13 pink or red yeast species belonging to the genus Rhodotorula. The total amount of lipid represented an average of 13% of the dry weight. The neutral and polar lipid fractions were analyzed separately. For all the strains studied, the major fatty acids in both fractions were oleic, linoleic and palmitic acids, which formed 80% of the total number of fatty acids. A notable amount of arachidonic acid, a precursor of eicosanoid hormones, was found in R. acheniorum, R. aurantiaca and R. bacarum. Depending on the strain, 1-10 carotenoid pigments were detected; beta-carotene was always the major carotenoid present.
对属于红酵母属的13种粉色或红色酵母菌株的脂质含量以及含有6至25个碳原子的脂肪酸组成进行了研究。脂质总量平均占干重的13%。分别对中性脂质和极性脂质部分进行了分析。对于所有研究的菌株，两个部分中的主要脂肪酸均为油酸、亚油酸和棕榈酸，它们占脂肪酸总数的80%。在山楂红酵母、橙色红酵母和巴氏红酵母中发现了大量花生四烯酸，它是类二十烷酸激素的前体。根据菌株不同，检测到1至10种类胡萝卜素色素；β-胡萝卜素始终是主要的类胡萝卜素。
