Rhamnose, glucose, glucosamine and 3-deoxy-D-mannooctulosonic acid were comon sugar constituents of all LPS preparations. 2-O-Me-fucose, 3-O-Me-fucose, 3-O-Me-rhamnose and 2-O-Me-galactose were found in LPSs of some A. brasilense strains. Fatty acid spectra from all LPSs studied were almost identical with predominance of 3-hydroxymyristic and 3-hydroxy-palmitic acids. 3-Hydroxypalmitic acid was the only amide-linked fatty acid. Lipopolysaccharides isolated from A. brasilense showed higher heterogeneity in sugar composition than those from A. lipoferum.enAzospirillum lipoferumAzospirillum brasilenseLipopolysaccharidesO-Methyl sugarsFatty acidsArticle
