title: Structural identification of the O-antigen fraction from the lipopolysaccharide of the Burkholderia ambifaria strain 19182.
abstract: The Burkholderia cepacia complex comprises a group of bacterial strains with both beneficial and detrimental effects to plant and animals. Gram negative bacterial lipopolysaccharide is one of the most important molecular factors involved in the dialogue between the microbe and the host and in this context we have isolated and identified the O-antigen fraction of the Burkholderia ambifaria strain 19182. It consists of two different O-polysaccharides built up on 6-deoxy sugars, among which the 6-deoxy-altrose in the d absolute configuration, is present. This monosaccharide is found for the first time and it is a unique feature associated to this strain.
