Effect of oxygen perturbations with host-microbiota feedback. The oxygen perturbation was set to one value in the legend at time zero and sustained throughout the simulation. a Linear relationship mimicking the putative host-microbiota feedback mechanism. b Biofilm oxygen concentration averaged across the biofilm. c–e Species abundances averaged across the biofilm. f Butyrate concentration averaged across the biofilm
