From: S-Adenosyl-L-Methionine protects the probiotic yeast, Saccharomyces boulardii,from acid-induced cell death

Figure 1

S. boulardii has decreased viability in ethanol, similar to S. cerevisiae. S. boulardii (Florastor) and S. cerevisiae (W303α) were cultured in rich YPD media overnight and resuspended in fresh media and allowed to reach exponential phase. They were then resuspended in fresh media or in fresh media containing 22% ethanol, allowed to grow at 30°C for the indicated times, serially diluted onto YPD plates, and cultured at 30°C for 2 days. Viability was measured as percentage colony forming units. At least three independent cultures were tested and compared. Note that after 3 hr, cells cultured in rich media without any cell death inducing agents were able to grow and to divide, hence the relative viability levels that are greater than 100%. The differences in viabilities were deemed statistically significant by the Student’s t-test (p<0.05)
