Cultivation profile of S. cerevisiae DS61143 in shake flasks under aerobic conditions with d-glucose as sole carbon and energy source. Concentrations over time are given for biomass (filled circle) (cell dry weight), for the substrate d-glucose (filled inverted triangle) and the products ethanol (square), glycerol (triangle), and acetate (square). Error bars indicate standard deviations of two independent measurements. Physiological phases are assigned according to the substrate uptake
