Abstract

The capsular polysaccharide from Butyrivibrio fibrisolvens strain X6C61 has been investigated using NMR spectroscopy, mass spectrometry, methylation analysis, and partial acid hydrolysis as the main methods. The polysaccharide is composed of hexasaccharide repeating units having the following structure. [formula: see text] The polysaccharide also contains O-acetyl groups, of which approximately 70% are substituted to O-3 of the beta-D-Glc pA residue.

摘要

已使用核磁共振光谱、质谱、甲基化分析和部分酸水解作为主要方法对来自溶纤维丁酸弧菌菌株X6C61的荚膜多糖进行了研究。该多糖由具有以下结构的六糖重复单元组成。[分子式：见正文]该多糖还含有O-乙酰基，其中约70%被取代到β-D-Glc pA残基的O-3位上。
