Fermentation product profiles in anaerobic bioreactor batch cultures of S. cerevisiae strains IMX585 (a GND1 GND2 GPD1 GPD2), IMX888 (b GND1 GND2 gpd2::eutE gpd1Δ), IMX860 (c gnd2Δ gnd1::gndA gpd2::eutE gpd1Δ). Glucose = filled circles; Biomass = filled squares; Glycerol = open squares; Ethanol = open circles; Acetate = open triangles. All cultures were grown on synthetic medium containing 20 g L⁻¹ glucose and 3 g L⁻¹ acetic acid (pH 5); d ratio of acetate to glucose consumption of the above cultures; e ratio of acetate consumption per biomass formed of the above cultures. a–c display single representative cultures from a set of two independent duplicate cultures for each strain. Data on ratios represent the average and mean deviation of independent duplicate cultures
