Description
  • Enterococci are common contaminants of human milk processed in milk banks, and the consumption of contaminated milk can cause severe infection-related complications if the control mechanisms fail to detect the contamination. Extensive data are available on the growth curves of E. faecium in broth at pH values between 6 and 7, at temperatures of 5 degrees C to 20 degrees C, and for water activity values a(w) of 0.97 to 0.997. These growth curves were replaced with non-linear Gompertz curves for microorganism growth, the parameters of which were correlated with the temperature and pH values. A mathematical relationship to water activity could not be established since only two water activity levels have been experimentally tested and the resulting model would be highly inaccurate. The issue of water activity was resolved by the development of two separate models, one for each of the water activity values.
