Fed-batch propagation–fermentation of S. cerevisiae Ethanol Red. Cultures were grown aerobically for 10 h using RB (circles) or MB (squares), followed by 45 h of ungassed anaerobic fermentation. a Cell density; b cell mass and viability; c residual glucose; and d ethanol produced. The data are the means and standard deviations (n = 4). Samples for transcriptome analysis were removed at 3 and 10 h during propagation and 7 and 32 h after commencing fermentation
