Growth rate evolution at different initial compositions. The growth rate between time points, taken by measuring biomass generated by dFBA at ti = t and tf = t + 5, was plotted versus time. Each line represents a different initial composition as listed on the graph (15:85 corresponds to 0.1 diazotroph:0.9 photoautotroph, etc.). All other conditions were held equal, and carbon uptake and nitrogen fixation were adapted from physiological data over 400 h intervals. The gray line represents the initial composition being set to the equilibrium composition. Growth was unachievable at initial compositions of 0:100 and 100:0
