Fig. 6From: An ensemble of mathematical models showing diauxic growth behaviourReaction schemes for models in group 2 (kinetics-based models with growth dilution). The models include induction of enzyme synthesis by the metabolites X1 and X2. In blue are shown different ways in which the dynamics of enzyme E1 can be modified, in every case leading to diauxic growth: (i) the maximum rate of enzyme synthesis (N1), (ii) the initial enzyme concentration (N2), (iii) the affinity of the inducer for its transcription factor and thus the effect on enzyme synthesis (N3), or (iv) the maximum rate of substrate uptake (N4)Back to article page
