Figure 2.

Physiological responses of aerobic glucose-limited chemostat cultures to fully fermentative conditions. Time zero represents the steady state value. A – Extracellular concentrations of glucose (black square), ethanol (black triangle), CO₂ (open square) and glycerol (black dot). Each time point represents the average of at least six independent replicates. B – Specific rates of glucose consumption (black square) and ethanol (black triangle), CO₂ (open square) and glycerol (black dot) production. C – Biomass dry weight (black square), whole cell protein (open square) concentrations and cell number (black triangle). D – Intracellular concentrations of trehalose (black square) and glycogen (open square). Each time point represents the average of at least two independent replicates.
