Twenty-seven strains belonging to 12 Mycobacterium species were studied for 3-hydroxy fatty acid composition. Mycobacterial cells were subjected to both mild and strong acid methanolysis, after which the liberated hydroxy fatty acids were purified and analyzed by gas chromatography-mass spectrometry as methyl ester trimethylsilyl ether derivatives. Altogether, 21 3-hydroxy fatty acids containing 14 to 28 carbon atoms were detected; 10 were straight chain, 6 were 2-methyl branched chain, and 5 were 2,4,6-trimethyl branched chain. The mycobacterial strains were classified in groups according to 3-hydroxy fatty acid patterns.
对属于12种分枝杆菌的27个菌株进行了3-羟基脂肪酸组成研究。分枝杆菌细胞分别进行了温和酸甲醇解和强酸甲醇解,之后将释放出的羟基脂肪酸纯化,并作为甲酯三甲基硅醚衍生物通过气相色谱-质谱联用仪进行分析。总共检测到21种含有14至28个碳原子的3-羟基脂肪酸;其中10种为直链,6种为2-甲基支链,5种为2,4,6-三甲基支链。根据3-羟基脂肪酸模式将分枝杆菌菌株分组。
