摘要本研究的目的是阐明芽孢形成和乳酸产生的益生菌菌株,凝结芽孢杆菌SANK 70258,对健康受试者和溃疡性结肠炎患者的人体结肠微生物群的影响。采用模型培养系统从粪便接种物构建体外人结肠微生物群,以保持细菌物种丰富度并模拟患者的无序组成。细菌16 S rRNA基因测序证实,B.在健康受试者(P= 0.016)和溃疡性结肠炎患者(P= 0.023)的微生物群模型中,凝固剂SANK 70258(初始浓度为4 × 107总细胞/mL)抑制了与肠杆菌科家族相关的细菌。此外,B.在健康受试者的微生物群模型中,凝结物SANK 70258增加了与毛螺菌科相关的细菌(P= 0.031),从而增强了丁酸盐的产生(P= 0.031)。然而,在溃疡性结肠炎患者的微生物群模型中没有观察到这些变化,可能是由于毛螺菌科物种的丰度低。这项研究表明了B。凝固剂SANK 70258对溃疡性结肠炎患者的有害微生物表现出抗菌活性,同时通过增加健康人的丁酸生成来改善肠道微环境。关键点·B.凝结物SANK 70258处理减少结肠肠杆菌科物种。B。凝结物SANK 70258处理增强健康个体的丁酸生成。B。凝结物SANK 70258治疗增加健康人中的毛螺菌。B。凝结物SANK 70258改善溃疡性结肠炎的结肠微环境。
AbstractThe aim of this study was to clarify the effect of the spore-forming and lactic acid-producing probiotic strain,Bacillus coagulansSANK 70258, on human colonic microbiota of healthy subjects and ulcerative colitis patients. A model culture system was employed to construct the in vitro human colonic microbiota, to retain the bacterial species richness and simulate the patient’s disordered composition, from the fecal inoculum. Bacterial 16S rRNA gene sequencing confirmed that administration ofB. coagulansSANK 70258 (at an initial concentration of 4 × 107-total cells/mL) suppressed bacteria related to the familyEnterobacteriaceaein the microbiota models for both healthy subjects (P= 0.016) and ulcerative colitis patients (P= 0.023). In addition, administration ofB. coagulansSANK 70258 increased bacteria related to the familyLachnospiraceae(P= 0.031), thereby enhancing butyrate production (P= 0.031) in the microbiota models of healthy subjects. However, these changes were not observed in the microbiota models of ulcerative colitis patients, likely owing to the low abundance ofLachnospiraceaespecies. This study demonstrates the potential ofB. coagulansSANK 70258 to exhibit antimicrobial activity against harmful organisms in patients with ulcerative colitis, while improving the intestinal microenvironment by increasing butyrogenesis in healthy persons.Key Points•B. coagulans SANK 70258 treatment reduced colonic Enterobacteriaceae species.•B. coagulans SANK 70258 treatment enhanced butyrogenesis in healthy individuals.•B. coagulans SANK 70258 treatment increased Lachnospiraceae in healthy persons.•B. coagulans SANK 70258 improves the colonic microenvironment in ulcerative colitis.
