By using cryo-scanning electron microscopy and quantification with lectin-conjugated probes, we have detected the production of exopolysaccharides (EPS) in Bifidobacterium animalis subsp. lactis in the presence of bile. In addition, the expression of gtf01207, which codifies a putative priming glycosyltransferase involved in EPS synthesis, was induced by bile.
通过使用低温扫描电子显微镜以及用凝集素偶联探针进行定量分析,我们检测到在胆汁存在的情况下,动物双歧杆菌乳酸亚种中胞外多糖(EPS)的产生。此外,编码一种推测参与EPS合成的起始糖基转移酶的gtf01207的表达受胆汁诱导。
