Twenty four strains representing eight species of gram positive yellow-pigmented rods (Oerskovia turbata, Oerskovia xanthineolytica, CDC Coryneform groups A-3, A-4, A-5, Listeria denitrificans, Corynebacterium aquaticum and Brevibacterium acetylicum) were divided into two major groups based on the relative amounts of 12 methyltetradecanoate (15:0a) obtained by capillary gas liquid chromatography. O. turbata, O. xanthineolytica, CDC groups A-3 and A-4, L. denitrificans and C. aquaticum were placed in the first group due to the presence of a higher percentage (29–47%) of 15:0a, than CDC group A-5 and B. acetylicum. The latter contained 2–6% of this fatty acid, and were placed in the second group.

All species in the two groups except C. aquaticum and CDC group A-4, were further separated from each other based on the qualitative and quantitative differences in their fatty acid compositions. In addition, the eight strains of CDC group A-5 revealed four different patterns and were further divided into four subgroups. This study supports the importance of the composition of cellular fatty acids in differentiating some closely related organisms.
