Saccharomyces boulardii (Sb) is a nonpathogenic yeast. Saccharomyces boulardii has a unique and specific microsatellite allele characteristics that distinguishes it from other strains of S. cerevisiae.

Most of the Saccharomyces strains have been shown to work optimally at temperatures between 22 °C and 30 °C; Saccharomyces boulardii , however, is able to survive temperatures of up to 37 °C, and therefore able to survive human body temperatures. The site of action for Saccharomyces boulardii is most commonly the colon and the yeast probiotic has been shown to survive passage to its target organ.

It is naturally resistant to antibiotics and proteolysis and able to survive in the competitive milieu of the intestinal tract. Saccharomyces boulardii has a strong affinity to various stresses like the presence of GI enzymes, bile salts, and organic acids.
