초록

Cellular fatty acid composition of eight strains, indluding six strains of Comamonas terrigena, and two type strains of Pseudomonas acidovorans, and P. testosteroni was determined by gas-liquid chromatography. Almost the same composition was found in all the strains tested, and hexadecanoic acid, hexadecenoic acid, and octadecenoic acid were accounted more than 70% of total fatty acid. However, P. testosteroni differed from C. terrigena and P. acidovorans by the presence of comparatively large amonuts of 2-hydroxy-hexadecanoic acid, and C. terrigena contained three to eight times as much tetradecanoic acid in P. acidovorans and P. testosteroni. According to the similarity values calculated on the basis of fatty acid composition, C. terrigena strains were divided into three groups differentiated in the requirement of growth factors, and C. terrigena, P. acidovorans, and P. testosteroni strains occupied separate position each other in the dendrogram.
