Figure 1From: The metabolic costs of improving ethanol yield by reducing glycerol formation capacity under anaerobic conditions in Saccharomyces cerevisiaeTime-courses of the mass of glucose, ethanol, biomass and glycerol in the fed-batch cultivations. Strains: Wild Type CEN.PK113-7D (WT), TEFmut7, and TEFmut2 strains. Mass of glucose (■), ethanol (▲), biomass (●) and glycerol (◇). Thick arrows indicate the time points when glucose feeding was carried out in order to adjust glucose concentration in the bioreactor up to 100 g L-1, thin arrows correspond to glucose feeding up to a concentration of 50 g L-1.Back to article page
