title: Structure of a neutral exopolysaccharide produced by Lactobacillus delbrueckii ssp. bulgaricus LBB.B26.
abstract: The neutral exopolysaccharide produced by Lactobacillus delbrueckii ssp. bulgaricus LBB.B26 in skimmed milk was found to be composed of d-glucose and d-galactose in a molar ratio of 2:3. Linkage analysis and 1D/2D NMR ((1)H and (13)C) studies performed on the native polysaccharide, and on an oligosaccharide obtained from a partial acid hydrolysate of the native polysaccharide, showed the polysaccharide to consist of branched pentasaccharide repeating units with the following structure.
