Fig. 6From: Escherichia coli metabolism under short-term repetitive substrate dynamics: adaptation and trade-offsIntracellular concentrations (μmol/gCDW) of nucleotides, as well as the adenylate energy charge (AEC), over a feast–famine cycle(s). Black horizontal dashed lines represent the average steady-state levels. Green vertical dashed lines show the end of the feeding (20 s). The pink area represents the substrate feast phaseBack to article page
