Summary Here we report on the presence of sulfated lipopolysaccharide molecules in Azospirillum brasilense , a plant growth‐promoting rhizosphere bacterium. Chemical analysis provided structural data on the O‐antigen composition and demonstrated the possible involvement of the nodPQ genes in O‐antigen sulfation.
