Abstract
The interaction of acidic capsular polysaccharide isolated fromKlebsiella K26 with cationic dyes pinacyanol chloride, acridine orange and phenosafranin has been studied by spectral measurements. The polymer induces metachromasy in pinacyanol chloride dye, indicating a blue shift in the visibly absorption spectrum of the dye from 600 to 500 nm. The stoichiometry of polymer/dye in the metachromatic compound, thermodynamic parameters of interaction, and effects of different cosolvents on the stability of the complex have been studied. Spectrophotometric and spectrofluorometric properties of the interaction between the polymer and all three dyes are presented. The chromotropic property of the polymer has been established.
