Daytime case study output. Daylight biomass-producing elementary modes, plotted for (A) compartmentalized, (B) pooled, and (C) nested simulations in terms of total consortium biomass yield on photons (Cmole/mole) and oxygen competition at the rubisco enzyme (O2 flux relative to CO2 flux). Each point represents a single mode. Solid line segments in (A) connect modes combined to represent ecological scenarios, while dashed lines represent the experimentally-derived limits for oxygen competition at the rubisco enzyme in the mid-afternoon. Arrows denote modes producing cyanobacterial biomass (see text for more details). Points are color-coded by biomass-producing guild (A &C) or SRB-associated reductive acetyl-CoA activity (B).
