Figure 8 .
Fermentation kinetics of the homozygous yeast deletion pool (S288C) compared with the EC1118 wine yeast strain in synthetic grape juice. Both strains [EC1118 (red diamonds) and diploid homozygous deletion set (S288C, light blue circles)] were fermented in triplicate. The average values are presented with error bars representing SD. (A) Cell growth curve measured by OD600, (B) glucose depletion, (C) ethanol production, and (D) yeast assimilable nitrogen [YAN, milligrams of nitrogen (N) per liter] measured from total ammonium sulfate and amino acids. Orange arrow in (A) marks when autophagic bodies are detected by electron microscopy. YAN, yeast assimilable nitrogen.
