Title: Preparation of bacterial lipopolysaccharides
Inventor: WORK ELIZABETH
IPC: A61K39/02
Filed: 1965-05-24
Abstract: A lipopolysaccharide is prepared by growing a lysine-requiring mutant of a Gram-negative species of bacteria in a sub-optional concentration of lysine obtaining a cell-free liquid from the resulting culture, separating a lipopoly saccharide, complex from the cell-free liquid, obtaining lipopolysaccharide by treatment with aqueous phenol, and finally removing the phenol. The lysine may take the form of a salt, or a material containing it, e.g. cornsteep liquor.  A specified bacterium is Escherichia coli, which is grown in a culture-medium containing 20-500 mg./1. of lysine, under conditions of high aeration, at 25-40 DEG  C.  for 24-48 hours.  The cell-free liquid may be obtained by centrifugation and membrane filtration, and the lipopolysaccharide complex (e.g. with lipoprotein and/or protein) partially purified by gel filtration or ultracentrifugation, followed by precipitation. A further purification may be effected by dissolving it in chelating agent (e.g. EDTA) and reprecipitating it. In the phenol treatment, two phases are formed, and the upper, aqueous phase is retained.  The phenol may be removed by dialysis, and the final product precipitated and freeze-dried.  The lipopolysaccharides may contain N or P and contain glucose, galactose, a heptose sugar and 2-keto-3-deoxyoctonic acid units.
