The following is a snippet from the report:


Yeast strains and growth conditions.A broad range of pathogenic and nonpathogenic yeasts were grown in yeast extract-peptone-dextrose (YPD) liquid medium (1% yeast extract, 2% peptone, 2% dextrose; Formedium, Norfolk, United Kingdom) at 35°C with shaking (150 rpm) until the exponential growth phase (details are presented in Table 1) (16). All of the strains were subjected to antifungal susceptibility testing, cell viability assays, and membrane potential evaluation. For membrane integrity, metabolic activity, reactive oxygen species (ROS) production, and apoptotic assays, only Saccharomyces cerevisiae BY4741 was used as a model organism. Prior to experiments, yeasts were subcultured twice in YPD agar to ensure the purity of cultures.
