Growth, glucose consumption and product formation in anaerobic bioreactor batch cultures of S. cerevisiae strains IME324 (GPD1 GPD2) (a) and IMX1489 (GPD1 gpd2Δ pTDH3-RPE1, pPGK1-TKL1, pTEF1-TAL1, pPGI1-NQM1, pTPI1-RKI1, pPYK1-TKL2 pDAN1-prk cbbm) (b). Cultures were grown on synthetic medium containing 20 g L⁻¹ glucose (pH 5). Symbols: black circle, glucose; black square, biomass; white square, glycerol; white circle, ethanol. Representative cultures of independent duplicate experiments are shown
