Abstract Cellular fatty acids of four rapid-growing mycobacterial species (Mycobacterium chelonei, M. fortuitum, M. phlei , and M. smegmatis ) were analysed by packed and capillary column gas chromatography after one, three, four, six, eight, and twelve days of incubation on Loewenstein-Jensen and Sauton agar media. Variations in incubation time did not affect the chromatograms except in the case of twelve-day incubated M. smegmatis . Mycobacteria cultivated on Sauton agar medium contained more tuberculostearic and less oleic acid compared with Loewenstein-Jensen. For informative and reproducible analytical results, the authors recommend using a chemically defined culture medium and splitless injection on a capillary column capable of separating not only the methyl esters of the cellular fatty acids acids but also the diagnostically important secondary alcohols containing 18 and 20 carbon atoms.
