sephadex g-50 gel-chromatography of a degraded polysaccharide fraction separated from the lps by 5 % acetic acid hydrolysis suggested that the o-specific polysaccharide region consists of , in average , as much as 29 moles of glc per 3 moles of l-d hep , while the core polysaccharide contains at least glc , l-d hep and glcn in molar ratios of 3.2 : 3.0 : 0.2 .
