对密歇根棒杆菌（Corynebacterium michiganense subsp.）从马铃薯和甜菜宿主中回收的Sepedonicum菌株用气-液色谱法测定。将脂肪酸谱与来自其他植物病原性棒状细菌的谱进行比较。C.密歇根亚种sepedonicum的主要成分是12-甲基-十四烷酸（α 15：0）、14-甲基-十六烷酸（α 17：0）、14-甲基-十五烷酸（α 16：0）、12-甲基-4-十四烯酸（α 15：1）、十六烷酸（16：0）、顺式-9-十八碳烯酸（18：1C）和顺式-9，12-十八碳二烯酸（18：2）。此外，一些菌株含有较少量的14、15、16、17、18和19碳脂肪酸。测试的所有植物病原性棒状细菌菌株可以基于总脂肪酸含量（定性）或通过细胞脂肪酸的比率（相对定量差异）来区分，例如，a15：0/i16：0、a17：0/i16：0、a15：0/a17：0、i16：0/a15：1、a15：1/16：0和16：0/18.
The cellular fatty acid composition of Corynebacterium michiganense subsp. sepedonicum strains recovered from potato and sugar beet hosts were determined using gas-liquid chromatography. Fatty acid profiles were compared to profiles from other plant pathogenic coryneform bacteria. The most prevalent fatty acids present in C. michiganense subsp. sepedonicum were 12-methyl-tetradecanoic acid (a15:0), 14-methyl-hexadecanoic acid (a17:0), 14-methyl-pentadecanoic acid (i16:0), 12-methyl-4-tetradecenoic acid (a15:1), hexadecanoic acid (16:0), cis-9-octadecenoic acid (18:1c), and cis-9,12-octadecadienoic acid (18:2). In addition, some strains contained smaller amounts of 14, 15, 16, 17, 18, and 19 carbon fatty acids. All strains of plant pathogenic coryneform bacteria tested could be differentiated on the basis of either total fatty acid content (qualitative) or by ratios of cellular fatty acids (relative quantitative differences), e.g., a15:0/i16:0, a17:0/i16:0, a15:0/a17:0, i16:0/a15:1, a15:1/16:0, and 16:0/18...
