a Growth profiles of each fed-batch bioreactor over time. Concentrations of glucose (yellow line) and ethanol (red line), OD₆₀₀ (green line) and the culture %DO (dotted line) are plotted against time for cells grown in different fed-batch regimes. b Population diversity of each fed-batch bioreactor over time. Depicted are the counts for barcodes that were detected (blue) and not detected (orange) at a given time point at a threshold of n = 10
