On the basis of non-destructive analysis by means of 1H and 13C NMR spectroscopy and calculation of specific optical rotation, it was concluded that O-specific polysaccharide of Pseudomonas cepacia strain IMV 4207 (serotype A) has the structure (I): (formula; see text) Two structurally different polysaccharides were found in the ratio of approximately 2.5:1 in P. cepacia strain IMV 598/2 which is serologically related to serotype A in Nakamura classification and serotype 2 in Heidt classification. The minor polysaccharide has the structure (I) whereas the major one possesses the structure (II) which is characteristic of the formerly studied O-specific polysaccharide of P. cepacia strain IMV 4137 belonging to serotype 2: ----4)-beta-D-Galp-(1----2)-alpha-L-Rhap-(1----.
基于通过1H和13C核磁共振光谱进行的无损分析以及比旋光度的计算，得出洋葱伯克霍尔德菌IMV 4207菌株（血清型A）的O-特异性多糖具有结构（I）：（分子式；见正文）在与中村分类中的血清型A和海德特分类中的血清型2血清学相关的洋葱伯克霍尔德菌IMV 598/2菌株中发现了两种结构不同的多糖，其比例约为2.5:1。次要多糖具有结构（I），而主要多糖具有结构（II），这是先前研究的属于血清型2的洋葱伯克霍尔德菌IMV 4137菌株的O-特异性多糖的特征：----4)-β-D-吡喃半乳糖-(1----2)-α-L-鼠李吡喃糖-(1----。
