Fig. 1From: An accurate description of Aspergillus niger organic acid batch fermentation through dynamic metabolic modellingCitric acid production commences upon a diauxic growth switch. Empirical data plotted are the mean average of four biological replicates and error bars represent standard deviation. Citric acid data are normalised to reflect the amount produced. a Change in biomass dry weight (g/L) over time. b Change in external citric acid concentration (g/L) over timeBack to article page
