A polysaccharide fraction was isolated from the Pantoea agglomerans IG1 lipopolysaccharide (IP-PA1), and its O-antigenic polysaccharide was characterized by chemical analyses and 1D and 2D H and C NMR spectroscopy. The polysaccharide is composed of linear tetrasaccharide repeating units, consisting of glucose and rhamnose, where 40% of one of the rhamnose residues is substituted with glucose: →2)-α-l-Rhap-(1→6)-α-d-Glcp-(1→2)-[β-d-Glcp-(1→3)]-α-l-Rhap-(1→2)-α-l-Rhap-(1→.
从成团泛菌IG1脂多糖（IP - PA1）中分离出一种多糖级分，其O抗原多糖通过化学分析以及一维和二维氢谱与碳谱核磁共振波谱进行表征。该多糖由线性四糖重复单元组成，包含葡萄糖和鼠李糖，其中一个鼠李糖残基的40%被葡萄糖取代：→2)-α - l - 鼠李糖基-(1→6)-α - d - 葡萄糖基-(1→2)-[β - d - 葡萄糖基-(1→3)]-α - l - 鼠李糖基-(1→2)-α - l - 鼠李糖基-(1→ 。
