Mycobacterium marinum and M. ulcerans were previously shown to synthesize lipid compounds which are stereochemically different from the corresponding molecules isolated from M. tuberculosis and other species. Stereochemical and biogenetic studies of

Distribution of radiolabelling in different parts of the newly synthesized mycolic acids, by a cell-free system from Mycobacterium aurum previously described, is examined, [1-14C]acetate being the precursor. By oxidation cleavage of mycolic acids and

The first cell-free system capable of synthesizing whole mycolic acids: (R1CH(OH)CH(R2)COOH, with 60 to 90 carbon atoms) from [1-14C]acetate is described and preliminary investigations into some of its requirements and properties are reported. Biosyn

The hypothetical schemes proposed for the biosynthesis of unsaturated mycolic acids (R1-CH(OH)-CH(R2)-COOH) of Mycobacteria cell walls were experimentally tested by using cell-free extracts either of Mycobacterium aurum or of Mycobacterium smegmatis

New methyl-branched fatty acids were isolated from the lipids of Mycobacterium aurum, belonging to both saturated and non-saturated series. The most abundant component of the former series was identified as a C22-mycosanoic acid (2-L, 4-L-dimethyleic

The isolation of a ‘palmitone lipid’ from Corynebacterium diphtheriae is described. The use of a temporary hydrophobic protecting group allows the obtaining of the lipid in free and pure form. Structural studies by chemical degradation and mass s

The fatty acyl moiety in lanosterol and dihydrolanosterol esters was determined by measurement of the metastable transition [M--15]+ leads to [M--15-fatty acid]+ which occurs in the first field free region of a double focusing mass spectrometer. The

The ‘cord factor’ from Corynebacterium diphtheriae was fractionated by thin-layer chromatography of the trimethylsilyl derivatives into three main components: the true ‘cord factor’ B1 which has been described previously and two compounds, B2

Several steroids generated by microbial fermentation of cholesterol were identified by the mass analysed ion kinetic energy (MIKE) spectra of their molecular ions generated under electron impact, and quantified by selected metastable ion monitoring.
