摘要：

The 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 x 10(3) kDa. Monosaccharide analysis, methylation analysis, MS, and 1D/2D NMR (H-1 and C-13) 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: [GRAPHICS] (C) 2001 Elsevier Science Ltd.
