An ornithine-containing lipid isolated from Gluconobacter cerinus.

The three ornithine-containing lipids of Gluconobacter cerinus were isolated from each other. One of the three lipids was postulated as Nalpha-3-hydroxypalmitoylornithine, to the fatty acid moiety of which 2-hydroxy fatty acid is linked by an ester linkage. The 2-hydroxy acid was possibly cis-11, 12-methylene-2-hydroxyoctadecanoate. Such an ornithine-containing lipid was found to be distributed in other acetic acid bacteria.
