摘要：

The exopolysaccharide produced by Lactobacillus paracasei 34-1 in a semi-defined medium was found to be a heteropolymer, composed of D-galactose, 2-acetamido-2-deoxy-D-galactose, and sn-glycerol 3-phosphate in molar ratios of 3:1:1. By means of deglycerophosphorylation, methylation analysis, and 1D/2D NMR studies (H-1, C-13, and P-31) the polysaccharide was shown to consist of repeating units with the following structure: [GRAPHICS] (C) 1996 Elsevier Science Ltd.
