Resumen en ingles

To exert their therapeutic action, probiotic Saccharomyces cerevisiae strains must survive harsh digestive environments. Lipid droplets accumulate in cells which undergo stress-inducing situations, supposedly having a protective role.We assessed lipid droplet levels, either naturally accumulated or induced in response to digestive challenges, of probiotic strains S. boulardii, S. cerevisiae A-905, S. cerevisiae Sc47 and S. cerevisiae L11, and of non-probiotic strains S. cerevisiae BY4741 and S. cerevisiae BY4743. Strains 905 and Sc47 had lower and higher lipid droplet levels, respectively, when compared to the remaining strains, showing that higher accumulation To exert their therapeutic action, probiotic Saccharomyces cerevisiae strains must survive harsh digestive environments.
