Diauxic Growth Model
Description
Dynamic Flux Balance Analysis of Diauxic Growth in Escherichia coli
The key variables in the mathematical model of the metabolic
network are the glucose concentration (Glcxt), the acetate concentration (Ac),
the biomass concentration (X), and the oxygen concentration (O2) in the gas phase.
