dBaranyi {biogrowth}

Baranyi growth model

Description

Microbial growth model as defined in Baranyi and Roberts (1994). It has been implemented according to the requirements of ode(). For consistency in the function for isothermal growth, calculations are done assuming the user input for mu is in log10 scale. In other words, the input is multiplied by ln(10).

Usage

dBaranyi(time, state, pars, env_func, sec_models)

Arguments

time

numeric vector (length 1) of storage time

state

named numeric vector with two components: Q and N

pars

named numeric vector of model parameters (Nmax and mu_opt)

env_func

named list of functions returning the values of the environmental conditions for time (t)

sec_models

named list of parameters of the secondary model

Value

A numeric vector of two components according to the requirements of ode().
