详细内容
厚壁菌门中的肠道罗斯拜瑞氏菌(Roseburia intestinalis),是常见的产丁酸菌,是人体肠道内降解膳食纤维木聚糖的关键细菌。Nature Microbiology上周发表的一项研究,详细解析了这种菌如何将木聚糖分解为木寡糖并内化、分解的分子机制,并发现其与另一种木聚糖降解菌有不同的木寡糖利用偏好,从而使二者在利用膳食木聚糖时可以实现共同生长的双赢局面。

Viability and purity assays of this product were performed at the time of production as part of quality control. The authenticity of the culture was confirmed by analyzing an appropriate gene sequence, e.g., the 16S rRNA gene for prokaryotes, the D1/D2 region of LSU rRNA gene, the ITS region of the nuclear rRNA operon, etc. for eukaryotes. The characteristics and/or functions of the strain appearing in the catalogue are based on information from the corresponding literature and JCM does not guarantee them.
肠道罗斯拜瑞氏菌如何利用和降解膳食木聚糖
①肠道罗斯拜瑞氏菌是降解膳食纤维木聚糖的关键肠道菌,可在多种木聚糖上生长,但偏好阿拉伯木聚糖;
②附于细菌表面的木聚糖酶RiXyn10A含有4个木聚糖结合模块,可捕获木聚糖分子,将之水解为木寡糖;
③经ABC转运体被细菌摄取,之后多种水解酶和乙酰酯酶参与木寡糖的降解;
④肠道罗斯拜瑞氏菌的ABC转运体主要摄取含4-5个木糖的木寡糖,与另一种降解木聚糖的拟杆菌对木寡糖的偏好不同,两种菌可在混合木聚糖培养基中共生长。
