Clin. and environmental strains of Burkholderia cenocepacia belonging to the recA lineages IIIA and IIIB were examd. for exopolysaccharide (EPS) prodn. The exopolysaccharides structure was detd. using mainly gas chromatog. coupled to mass spectrometry and NMR spectroscopy. All the strains produced Cepacian, a highly branched polysaccharide constituted of a heptasaccharide repeating unit, composed of one rhamnose, one glucose, one glucuronic acid, one mannose and three galactose residues. This polymer is the most common exopolysaccharide produced by strains of the Burkholderia cepacia (Bcc) complex. One clin. strain produced also another polysaccharide constituted of three galactose units and one 3-deoxy-d-manno-2-octulosonic acid residues, a polymer that was previously isolated from two strains of B. cepacia genomovar I and B. cenocepacia IIIA.

Abstract
Clin. and environmental strains of Burkholderia cenocepacia belonging to the recA lineages IIIA and IIIB were examd. for exopolysaccharide (EPS) prodn. The exopolysaccharides structure was detd. using mainly gas chromatog. coupled to mass spectrometry and NMR spectroscopy. All the strains produced Cepacian, a highly branched polysaccharide constituted of a heptasaccharide repeating unit, composed of one rhamnose, one glucose, one glucuronic acid, one mannose and three galactose residues. This polymer is the most common exopolysaccharide produced by strains of the Burkholderia cepacia (Bcc) complex. One clin. strain produced also another polysaccharide constituted of three galactose units and one 3-deoxy-d-manno-2-octulosonic acid residues, a polymer that was previously isolated from two strains of B. cepacia genomovar I and B. cenocepacia IIIA.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
