Metabolic Modeling to Predict Organism Phenotypes

Here we explore one of the major applications of steady-state metabolic modeling: the prediction of organism growth rates under varying perturbations.  The two most common perturbations studied with metabolic models are variations in the nutrients available to the organism (e.g., changes in carbon source, nitrogen source, and oxygen availability), and the presence of gene knockouts.  These two perturbations can be combined since the effects of gene knockouts can be modeled under different nutrient mixes.
