Concentrations of aroma compounds (in parts per million) produced by
the diploid WT Y182 strain and the isogenic ATF1 double-deletion mutant
during fermentation (see Figure S1 for more information on Y182). For
each strain, four fermentations were performed and each was analyzed
in four technical replicates. Acetate esters are displayed in bold. These
results demonstrate that the only compounds significantly affected by
the ATF1 deletion are acetate esters (ND, not detected). Production of
these aroma compounds by non-Saccharomyces strains may be found
in Table S2.
a Significant difference between the WT and deletion strain (p < 0.05).
