Evaluation the Viability of the Saccharomyces Boulardii Bld-3 and its Influence on the Colonic Microbiota Composition by SHIME

During this study the viability of Saccharomyces Boulardii Bld-3 during passage through the upper GIT under fed and fasted conditions was evaluated. For this purpose, a Simulator of the Human Intestinal Microbial Ecosystem (SHIME®) was used, which allows to re-create the physiological conditions that are representative of the human GIT. Furthermore, the aim of this study was also to study the modulatory effect of the Saccharomyces Boulardii Bld-3 on the colonic microbiota composition and activity after passage of the strain through the fed or fasted upper GIT or when delivered directly to the colon. For this purpose, four different types of short-term colonic batch experiments were performed that simulate the colonic fermentation process.
