[The characteristics of the lipid A of the lipopolysaccharides in Pseudomonas syringae strains].

Component composition of lipid A of Pseudomonas syringae pv. syringae 218 and P-55, pv. syringae (holci) 8299, pv. phaseolicola 120a, pv. atrofaciens 2399 has been studied. The lipid A composition of all the strains studied includes 3-hydroxydecanoic fatty acid (3-OH-C10:0), 2-hydroxydodecanoic (2-OH-C12:0), 3-hydroxydodecanoic (3-OH-C12:0), dodecanoic (C12:0), hexadecanoic (C16:0), octadecanoioc (C18:0), hexadecenic (C16:1), octadecenic (C18:1) fatty acids. The carbohydrate part of the lipid A macromolecule of all strains after acid hydrolysis contains ethanolamine, phosphoethanolamine, glucosamine.
