Growth, glucose consumption and product formation in anaerobic bioreactor batch cultures of S. cerevisiae strains with different genetic modifications in glycerol and acetate metabolism. Cultures were grown on synthetic medium containing 20 g L⁻¹ glucose and 3 g L⁻¹ acetic acid (pH 5). a strain IME324 (GPD1 GPD2); b strain IMX992 (GPD1 GPD2 sga1::eutE); c strain IMX884 (GPD1 gpd2::eutE); d strain IMX776 (gpd1::gpsA gpd2::eutE); e strain IMX901 (gpd1::gpsA gpd2::eutE ald6Δ); f strain IMX888 (gpd1Δ gpd2::eutE). Closed circle glucose; closed square biomass; open square glycerol; open circle ethanol; open triangle acetate. a–f display single representative cultures from a set of two independent duplicate cultures for each strain. Data on strain IMX888 were taken from [29]
