采用气相色谱-质谱对采自云南白马雪山土壤中并经分离和发酵培养的被孢霉菌株SM96的菌丝体油脂中脂肪酸组成进行了定性分析和峰面积相对含量测定,共检测出30种脂肪酸,其中多不饱和脂肪酸含量为62.4%,主要为亚油酸、α-亚麻酸(ALA),还有少量的γ-亚麻酸、二十碳三烯酸、花生四烯酸和二十碳五烯酸(EPA)等,结果表明该菌株能产生EPA。 |

The components of fatty acids in mycelium oil of Mortierella fungus, which picked from the Baima Snow Mountain in Yunnan Province, were analyzed by GC - MS. 30 fatty acids were identified and their relative contents were determined by normalization method of area, of which polyunsaturated fatty acids accounted for 62.4% , and they mainly comprised linoleic acid, a-linolenic acid and eicosapentaenoic acid (EPA) . The results indicated that the Mortierella fungus could produce EPA |
