Effect of different oxygen concentrations on the steady-state behavior of the biofilm community. The bulk oxygen concentration was set to a fixed value between 0 and 5x10 −3 mM for each simulation. a Species abundances (%) averaged across the biofilm for the range of bulk oxygen concentrations. b Species O2 uptake rates (mmol/gDW/h) for three bulk oxygen concentrations. c-e Growth rates (h −1) of B. thetaiotaomicron, F. prausnitzii and E. coli relative to their anaerobic values for three bulk oxygen concentrations. f–h Uptake rates (mmol/gDW/h) of cross-fed byproducts relative to their anaerobic values for three bulk oxygen concentrations
