Diauxic Growth Model
Model version: 9
TOP model
Main comp DFBA model by combining fba, update and bounds model with additional kinetics in the top 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.
