Revised structure of the repeating unit of the O-specific polysaccharide from Azospirillum lipoferum strain SpBr17.


A neutral O-polysaccharide liberated by mild acid hydrolysis of a lipopolysaccharide isolated from Azospirillum lipoferum SpBr17 was investigated using 1D and 2D (1)H and (13)C NMR spectroscopy, including HSQC, HMBC, and NOESY as well as SDS-PAGE electrophoresis along with sugar and methylation analyses. The structure of the O-specific polysaccharide… (More)
