This paper reports some physicochemical properties of the capsular polysaccharide produced by Klebsiella pneumoniae serotype K40 (K40-CPS) in aqueous solution. The polymer has a linear hexasaccharide repeating unit containing one glucuronic acid residue as the only ionizable group. Potentiometric, viscometric, chiro-optical and rheological measurements have been carried out over a range of ionic strength, pH and temperature, with the aim of characterizing the conformational state of the polysaccharide in aqueous solution. All the data reported indicate that the K40-CPS does not undergo a cooperative conformational transition under the investigated experimental conditions. Furthermore, the viscosity data and the viscoelastic spectra suggest that the K40-CPS is rather flexible and adopts a random coil conformation in solution.
