Abstract Four long-chain fatty acids, 2-hydroxy-27-oxo-octacosanoic acid (n28:0(2-OH,27-oxo)), 2-hydroxy-29-oxo-triacontanoic acid (n30:0(2-OH,29-oxo)), 2-hydroxy-heptacosane-1,27-dioic acid (27:0(2-OH)-dioic) and 2-hydroxy-nonacosane-1,29-dioic acid (29:0(2-OH)-dioic) were identified by GLC-MS analysis in the phenol-chloroform-petroleum ether (PCP) extracts of Legionella jordanis, L. maceachernii and L. micdadei indicating that they are constituents of lipopolysaccharide. Moreover, five long-chain fatty acids (28:0(27-OH), 28:0(27-oxo), 30:0(29-oxo), 27:0-dioic and 29:0-dioic) previously identified in L. pneumophila (Moll, H. et al., FEMS Microbiol. Lett., 97 (1992), 1–6) were also found in these species. This is to our knowledge the first report on the existence of long chain 2-hydroxylated (ω-1)-oxo fatty acids and 2-hydroxylated 1,ω-dioic fatty acids.
