Comparison of S. boulardii cells in H2O vs. S. boulardii cells in H2O+HCl

We sought to better understand the mechanism of acid-induced cell death in Saccharomyces boulardii--a probiotic yeast routinely used to prevent and treat gastrointestinal disorders. To do this we generated microarray gene expression profiles of S. boulardii cells cultured in an acidic environment. Two samples were analyzed. One replicate per array.
