Fig. 7From: The use of genome-scale metabolic network reconstruction to predict fluxes and equilibrium composition of N-fixing versus C-fixing cells in a diazotrophic cyanobacterium, Trichodesmium erythraeum 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 Back to article page
