The biomass equation is the molar concentration of the metabolite predicted by the computational molar mass and uses the values from the ambient air (N2) grown cultures. The “Soluble Pool” is a collection of soluble metabolites that are more or less conserved between organisms for survival (including small sugars, energy carrying molecules, etc.) aSubset of protein measurement. bSubset of lipid measurement
