The structure of the repeating unit of the capsular polysaccharide from Escherichia coli serotype K36 has been established from the results of spectroscopic and chemical analyses of (a) P1, the tetrasaccharide obtained on depolymerisation of the polysaccharide with a bacteriophage-borne endo-galactosidase, (b) P1-alditol, and (c) the original polysaccharide. The repeating unit, which is identical to that reported for Klebsiella K57, has the following structure. (Formula: see text).
通过对以下物质进行光谱分析和化学分析，确定了大肠杆菌血清型K36荚膜多糖重复单元的结构：(a) P1，用噬菌体携带的内切半乳糖苷酶使多糖解聚得到的四糖；(b) P1-木糖醇；(c) 原始多糖。该重复单元与报道的肺炎克雷伯菌K57的重复单元相同，具有以下结构。（分子式：见正文）
