MicrobialGrowth (version 1.0.0)

Estimates Growth Parameters from Models and Plots the Curve

Description

Fit growth curves to various known microbial growth models automatically to estimate growth parameters. Growth curves can be plotted with their uncertainty band. Growth models are: modified Gompertz model (Zwietering et al. (1990) ), Baranyi model (Baranyi and Roberts (1994) ), Rosso model (Rosso et al. (1993) ) and linear model (Dantigny (2005) ).
