Analysis of the lipid moiety of lipopolysaccharide from Rhizobium tropici CIAT899: identification of 29-hydroxytriacontanoic acid

Abstract

The lipid moieties of two lipid A's isolated from the phenolic and aqueous fractions of lipopolysaccharide from Rhizobium tropici CIAT899 have been studied. Several 3-hydroxy fatty acids and two long-chain hydroxy fatty acids, 27-hydroxyoctacosanoic acid, and 29-hydroxytriacontanoic acid were identified; the ratios of these acids are the same in both lipid A's. These results can be used for chemotaxonomic purposes.
