Modelling the Biphasic Growth and Product Formation by Enterococcus faecium CECT 410 in Realkalized Fed-Batch Fermentations in Whey

Figure 3

Time course of the realkalized fed-batch culture of Ent. faecium CECT 410 on whey with feeding with a 400 g/L concentrated lactose (fed-batch fermentation I). AA: acetic acid, EtOH: ethanol, B: butane-2,3-diol. Other notations are as in Figure 1. Data reported are means ± standard deviations of three replicates. The solid lines drawn through the experimental data of biomass and lactic acid were obtained according to the models (A.6) and (A.7), respectively. The solid lines drawn through the experimental data for AA, EtOH, and B were obtained according to the model (A.9).
