Research progress and application prospects of postbiotics derived from Saccharomyces boulardii

Saccharomyces boulardii is a non-pathogenic yeast and one of the most well-known probiotic yeast. Since its discovery, it has been widely used as a health supplement and medical products globally, being a yeast with various biological activities. Clinical studies have shown that S. boulardii can improve intestinal diseases, irritable bowel syndrome, and Helicobacter pylori infections, and it possessed anti-cancer, immunomodulatory, antibacterial, antiviral, and antioxidant functions. In recent years, with the development of microbial ecology and nutrition, the research on S. boulardii as a postbiotics has attracted widespread attention in the scientific community. However, the research on postbiotics derived from S. boulardii is still in its infancy. Based on this point of view, the biological characteristics of S. boulardii and its action mechanism in the body, as well as the application prospect of postbiotics derived from S. boulardii in food and medicine were reviewed, in order to provide a theoretical basis for the wide application of postbiotics derived from S. boulardii.
