Abstract
A fast-growing, non-photochromogenic mycobacterium isolated from the environment exhibited, on thinlayer chromatograms, a characteristic pattern of mycolates composed of unsaturated mycolates and also an unknown more polar component. Spectroscopic analysis and chemical degradation showed that this latter component was a novel mycolic acid containing a methoxy group at the ω-1 position (instead of ω–17 and ω–18 in known methoxymycolates), and two double bonds in the long mero aldehyde chain (instead of one as in known mycolates with additional oxygenated groups).
