Growth model of E. faecium - file of MS Excel

Popis výsledku v původním jazyce

Growth curves of E. faecium were completed and a mathematical model of its growth was finalized. The aim of the work was to acquire growth data of E. faecium CCM 2308 as dependent on temperature ranging from 5 to 20 °C, pH between 6 and 6.8 and water activity within the range of 0.97 or 0.997. All the cultivations were replicated three times and pH of the bouillon of the aseptically taken samples was measured repeatedly. These data were replaced by a non-linear Gompertz model of the bacterial growth curve, whose parameters were correlated with temperature and pH. Two models were created, each of them valid for a different water activity of growth bouillon. The model valid for a water activity value of 0.997 was validated using growth data obtained by cultivating the bacteria in breast milk and cow's milk. The fit between the predicted growth curves and experimental data is very good. In breast milk the growth model mostly predicted a faster growth than found experimentally. The model t
