Table 1. Focal EFMs representing different growth strategies.
Metabolic fluxes are given in carbon moles (or O2 moles) per carbon moles of glucose uptake. Growth rates are given for reference conditions [glucose] = 100 mM, and [O2] = 0.21 mM. For more details, see Table 10 in S1 Text. Abbreviations: * max-gr: maximum growth rate; max-yield: maximum yield; pareto: a Pareto optimal EFM with higher growth rate than max-yield, and higher yield than max-gr; ana-lac: anaerobic lactate fermentation; aero-ace: aerobic acetate fermentation; exp: experimentally measured flux distribution.
