[Fatty acid composition of lipid A in Pseudomonas fluorescens].
The fatty acid composition of lipid A was studied using gas-liquid chromatography (GLC) and GLC-mass spectrometry in Pseudomonas fluorescens strains of biovars A, B, C, i, F and G, the type strain ATCC 13525 (biovar A) inclusive. The following fatty acids were identified as predominant in the composition of lipid A in the strains representing biovars A, B, C, i, F and G: 3-hydroxydecanoic (3-OH C10:0), 2-hydroxydodecanoic (2-OH C12:0), 3-hydroxydodecanoic (3-OH C12:0), dodecanoic (C12:0), hexadecanoic (C16:0), octadecanoic (C18:0), hexadecenoic (C16:1) and octadecenoic (C18:1) acids. Lipid A of a biovar G strain differed noticeably from other strains in its fatty acid composition. Its main components were as follows: 3-hydroxytetradecanoic (3-OH C14:0), 3-hydroxypentadecanoic (3-OH C15:0) and dodecanoic (C12:0) fatty acids. The coefficients of similarity were determined for lipid A specimens isolated from the studied strains of P. fluorescens by calculating their fatty acid composition with a computer.
