Nitrogen and biomass production based on variable initial cell concentrations. 1000 iterations were run with randomly generated initial biomasses of each cell type and run for 400 h to simulate laboratory measured behavior. a Fraction of fixed nitrogen released calculated by the average amount of fixed nitrogen accumulated in the medium of a Batch Reactor model divided by the average fixation rate over the time period. Values are clustered between 25% and 45% except for non-growth cases where no nitrogen was released because death was assumed. b Growth Rate over all iterations. Non-growth cases resulted in zero, but otherwise a bimodal distribution existed. This can be coupled with 0.1544:0.8456 diazotroph: photoautotroph ratio determined by simulation.photoautotroph ratio determined by simulation. The dotted black line refers to laboratory measured growth at 0.0146 h-1
