Bacterial lipid macroamphiphiles extracted with phenol/water can be purified in one step by hydrophobic interaction chromatography. Lipids and the major part of protein are separated from macroamphiphiles during phenol/water extraction. Coextracted nucleic acids, polysaccharides, and residual protein are effectively removed by column chromatography on octyl-Sepharose whereby macroamphiphiles are primarily adsorbed and later eluted with a buffered propanol gradient. The procedure is applicable to macroamphiphiles with various lipid structures as was demonstrated using the diacylglycerol-containing lipoglycan of Micrococcus luteus, the lipid A-containing lipopolysaccharide of Salmonella typhimurium, and the diglyceryl tetraether lipoglycans of Thermoplasma acidophilum and Thermoplasma volcanicum. On elution from octyl-Sepharose, separation into molecular species of different compositions was observed with the lipopolysaccharide of S. typhimurium and the lipoglycan of T. volcanicum. It was also shown that, after phenol/water extraction, membrane lipids are completely recoverable from the phenol layer, which makes it possible to isolate lipids along with macroamphiphiles from the same sample of bacteria.
