  • Title: Nonpolar lipids of a halotolerant species of Staphylococcus epidermidis.
    Author: Kushwaha SC, Kates M.
    Journal: Can J Biochem; 1976 Jan; 54(1):79-85. PubMed ID: 1252986.
    Abstract:
    The nonpolar lipids of a halotolerant Staphylococcus epidermidis, isolated in pure culture from a growth medium for extreme halophiles containing 25% sodium chloride, were found to contain squalene, menaquinone-7, free fatty acids (mainly anteiso-15:0 and anteiso-17:0), undecaprenol, nonaprenol with predominately cis-isoprene residues, heptaprenol, with predominately trans-isoprene residues, and 1,2- and 1,3-diglycerides containing anteiso- 15:0 and anteiso-17:0 branched chain fatty acid residues. The above compounds were isolated in pure form by column and thin-layer chromatography and were characterized by ultraviolet, proton magnetic resonance, and mass spectra. Fatty acid moieities were characterized by gas-liquid chromatographic retention times of their methyl esters.
