Cultivation profile of S. cerevisiae DS61180 in shake flasks under microaerobic conditions with l-arabinose as sole carbon and energy source. Concentrations over time are given for cell dry weight (filled diamond), for l-arabinose (filled inverted triangle) and the products ethanol (square), acetate (circle), and glycerol (triangle). Error bars indicate standard deviations of two independent measurements. Physiological phases are assigned according to the rate of growth and substrate uptake
