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 (1H, 13C, and 31P) the polysaccharide was shown to consist of repeating units with the following structure: [formula: see text].
副干酪乳杆菌34-1在半限定培养基中产生的胞外多糖被发现是一种杂聚物，由D-半乳糖、2-乙酰氨基-2-脱氧-D-半乳糖和sn-甘油3-磷酸以3:1:1的摩尔比组成。通过去甘油磷酸化、甲基化分析和1D/2D NMR研究（1H、13C和31P）表明，该多糖由具有以下结构的重复单元组成：[化学式：见原文]
