On the basis of chemical degradation methods and one-and two-dimensional 1H and 13C NMR experiments the novel following structure was established for the O-deacetylated repeating unit of the O-chain of the main Burkholderia (Pseudomonas) cepacia (strain PVFi-5A) lipopolysaccharide: -->4)-beta-D-GalpNAc-(1-->3)-alpha-D-Galp-(1-->6)-alpha-D-GlcpNAc-(1-->.
基于化学降解方法以及一维和二维氢谱与碳谱实验，确定了洋葱伯克霍尔德菌（假单胞菌属）洋葱伯克霍尔德菌（菌株PVFi - 5A）主要脂多糖O链的O - 脱乙酰化重复单元的如下新结构：-->4)-β - D - 氨基半乳糖-(1-->3)-α - D - 半乳糖-(1-->6)-α - D - N - 乙酰葡糖胺-(1-->。
