Description:
The MRV (Microbial Responses Viewer) is a new database consisting of microbial growth/no growth data
derived from ComBase. Furthermore, the specific growth rate of each microorganism was modelled as a
function of temperature, pH, and water activity (aw) using three different models. The retrieved data of
the growth/no growth data and specific growth rate model are illustrated in a figure.
Seventeen kinds of microorganism with growth/no growth data were extracted from all the data in
ComBase comprising 30 kinds of microorganism. These data were successfully modelled as a function
of temperature, pH, and water activity. The specific growth rate was illustrated using a two-dimensional
contour plot with growth/no growth data.
Additionally, current MRV enables the comparison of the growth rate as a function of temperature
among kinds of bacteria and kinds of food.
