Abstract

The structure of the capsular polysaccharide isolated from Klebsiella K68 bacteria has been elucidated by both chemical and spectroscopic methods. The structure is of the "3 + 1" type, similar in pattern to the structures of the polysaccharides of Klebsiella K11 and K57, having a single branch point on the uronic acid. The polysaccharide is shown to consist of the following repeating unit: (Formula: see text).

摘要

通过化学和光谱方法已阐明了从肺炎克雷伯菌K68菌株中分离出的荚膜多糖的结构。该结构为“3 + 1”型，在模式上与肺炎克雷伯菌K11和K57多糖的结构相似，在糖醛酸上有一个单一的分支点。已证明该多糖由以下重复单元组成：（分子式：见正文）
