Abstract
A putative capsular polysaccharide containing d-rhamnose was isolated from the phytopathogenic bacterium Burkholderia gladioli pv. agaricicola by phenol/water extraction followed by ultracentrifugation of the separated water phase and gel-permeation chromatography of the thus obtained supernatant. By means of chemical analyses and NMR spectroscopy, the repeating unit of the polymer was shown to be a linear tetrasaccharide with the structure. →4)-α-D-Rhap-(1→3)-α-D-Rhap-(1→3)-α-D-Rhap- (1→3)-β-D-Rhap-(1→I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
