Abstract EN
The influence of initial pH on growth and nutrient (total sugars, nitrogen, and phosphorous) consumption by Enterococcus faecium CECT 410 was studied during batch cultures in whey.
With these data, two realkalized fed-batch fermentations were developed using different feeding substrates.
The shift from homolactic to mixed acid fermentation, the biphasic kinetics observed for cell growth and nitrogen consumption and the increase in the concentrations of biomass and products (lactic acid, acetic acid, ethanol, and butane-2,3-diol) were the most noteworthy observations of these cultures.
Modelling the fed-batch growth of Ent.
faecium with the Logistic and bi-Logistic models was not satisfactory.
However, biomass production was best mathematically described with the use of a double Monod model, which was expressed in terms of biomass, product accumulation, and nitrogen utilization.
Product formation was successfully modelled with a modified form of the Luedeking and Piret model developed in this study.
