Review articleOpen access
Abstract:

AbstractThe lactic acid bacterium Lactobacillus delbrueckii subsp. bulgaricus 291, when grown in skimmed milk, produced 80 mg/L exopolysaccharide with an average molecular mass of 1.4×103 kDa. Monosaccharide analysis, methylation analysis, MS, and 1D/2D NMR (1H and 13C) studies performed on the native polysaccharide, and on oligosaccharides obtained from a mild acid hydrolysate of the native polysaccharide, showed the polysaccharide to consist of branched pentasaccharide repeating units with the following structure:Download full-size image
