Project description:A transcriptome analysis of the bottom-fermenting yeast S. pastorianus KBY011 during a time course of lager beer fermentation in the wort was carried out (0, 2, 6, 8, 10, 14, 24, 34, 40, 52, 64, 120, and 156h). RNA preparation followed by DNA microarray analysis was performed for the yeast harvested from the yeast storage tank either just prior to, or just after the actual fermentation, as well as from 12 different time points during fermentation.
