Intracellular carbon fluxes distributions during xylose catabolism to ethanol production. S. stipitis (green), S. arborariae (red), and S. passalidarum (blue). Xylose consumption rates are represented by a negative signal. The first intracellular reaction (xylose to xylitol) shows two arrows; left represents reaction using NADPH, right represents reaction using NADH cofactor. The extracellular metabolites highlighted in black boxes had its flux rates used as constraints to the MFA-calculated
