Relative quantification and reproducibility of ethanol synthesis (integral of the resonance at 1.15 to 1.20 ppm) by various yeast strains in the presence of AMB. Yeasts were incubated for 24 h with 0, 0.5, 1, 2, and 5 μg/ml of AMB. Integrals were quantified relative to the ethanol signal in the yeast suspension without AMB after 24 h (for each strain). Ethanol was quantified after 1, 3, 6, 12, and 24 h. (A) Mean values and standard deviations (error bars) from three C. albicans isolates (two cultures per isolate) with MICs between 0.06 and 0.12 μg/ml. (B) Mean values and standard deviations (error bars) from one C. lusitaniae isolate (97-291-0929, two cultures) with a MIC of 0.5 μg/ml. (C) Mean values and standard deviations (error bars) from one T. beigelii isolate (two cultures) with a MIC of 4 μg/ml.
