Abstract:
:The solubilities of extracellular polysaccharide fractions produced by 14 oral streptococcal strains were compared in water, aqueous lithium and guanidine salt solutions, dimethyl sulfoxide (DMSO), and a 9:1 DMSO-water mixture. The best results for solubilizing the fractions were obtained with the DMSO-water mixture procedure, which used the water and DMSO in sequence. By this method all fo the fractions were solubilized.
