GLC was used to study the composition of endocellular fatty acids of Actinomyces canosus 89 grown on a chemically defined medium and on a complex medium to which various components were added. Total lipids of the culture contain saturated and unsaturated fatty acids, from C13 to C18, with one or two double bonds. Addition of components to the medium stimulated the biosynthesis of myristic, stearic, oleic, and linoleic fatty acids. Changes in the composition of the growth medium modify the ratio between saturated and unsaturated fatty acids of total lipids, increasing the content of unsaturated fatty acids due to a higher rate of synthesis of linoleic and oleic fatty acids. An increase in the content of unsaturated fatty acids is a positive factor because these acids are involved in important physiological functions of both this organism and other living organisms.
利用气相色谱法（GLC）研究了生长在化学成分确定的培养基以及添加了各种成分的复合培养基上的犬放线菌89细胞内脂肪酸的组成。培养物的总脂质含有从C13到C18的饱和脂肪酸和不饱和脂肪酸，带有一个或两个双键。向培养基中添加成分刺激了肉豆蔻酸、硬脂酸、油酸和亚油酸的生物合成。生长培养基组成的变化改变了总脂质中饱和脂肪酸和不饱和脂肪酸之间的比例，由于亚油酸和油酸的合成速率较高，不饱和脂肪酸的含量增加。不饱和脂肪酸含量的增加是一个积极因素，因为这些脂肪酸参与了该生物体以及其他生物体的重要生理功能。
