Normoxic and microaerophilic growth of C. albicans, S. cerevisiae, and C. glabrata strains. A dilution series (10-fold) of cells were grown for 48 h under normoxic and microaerophilic conditions at 30°C on various agar media. CSM (CSM complete supplemented with uridine), TW (Tween 80, 0.1%), Chol (cholesterol, 20 μg/ml), and FLC (fluconazole, 256 μg/ml) were used. S. cerevisiae parental strains differ for the UPC2 mutants (W303-1a) and the AUS1/PDR11 mutant (BY4742) and thus are presented separately with the appropriate mutants. CSM supplemented with Tween 80 was performed, and it was not significantly different from CSM alone (data not shown).
