The fatty acid profiles of 74 strains of mycolic acid-containing coryneform bacteria were examined by gas-liquid chromatography. All of the strains contained major amounts of straight-chain and monounsaturated fatty acids although some also possessed substantial amounts of 10-methyloctadecanoic acid. Iso- and anteiso-branched acids were not present. Five distinct fatty acid patterns were evident: (i) Corynebacterium diphtheriae, C. pseudotuberculosis and 'C. ulcerans' strains contained major amounts of hexadecanoic and hexadecenoic acids; (ii) C. glutamicum, C. xerosis and related saprophytic and animal-associated strains, predominantly hexadecanoic and octadecenoic acids; (iii) C. bovis, major amounts of octadecenoic and 10-methyloctadecanoic acids; (iv) 'C. mycetoides', significant amounts of heptadecanoic acid as well as hexadecanoic and octadecenoic acids; and (v) strains related to Rhodococcus possessed significant quantities of 10-methyloctadecanoic acid in addition to straight-chain and monounsaturated acids.
通过气液色谱法检测了74株含分枝菌酸棒状杆菌的脂肪酸谱。所有菌株都含有大量直链和单不饱和脂肪酸，不过有些菌株还含有大量的10-甲基十八烷酸。不存在异支链和反异支链酸。明显有五种不同的脂肪酸模式：（i）白喉棒状杆菌、假结核棒状杆菌和“溃疡棒状杆菌”菌株含有大量的十六烷酸和十六碳烯酸；（ii）谷氨酸棒状杆菌、干燥棒状杆菌以及相关腐生菌和动物相关菌株，主要是十六烷酸和十八碳烯酸；（iii）牛棒状杆菌，大量的十八碳烯酸和10-甲基十八烷酸；（iv）“类真菌棒状杆菌”，大量的十七烷酸以及十六烷酸和十八碳烯酸；（v）与红球菌相关的菌株，除直链和单不饱和酸外，还含有大量的10-甲基十八烷酸。
