Molecular and physiological comparisons between Saccharomyces cerevisiae and Saccharomyces boulardii.


In this paper, comparative molecular studies between authentic Saccharomyces cerevisiae strains, related species, and the strain described as Saccharomyces boulardii were performed. The response of a S. boulardii strain and a S. cerevisiae strain (W303) to different stress conditions was also evaluated. The results obtained in this study show that S. boulardii is genetically very close or nearly identical to S. cerevisiae. Metabolically and physiologically, however, it shows a very different behavior, particularly in relation to growth yield and resistance to temperature and acidic stresses, which are important characteristics for a microorganism to be used as a probiotic.
