Average growth rates along the colon, when cells flow through the colon as fast as metabolites. Average are taken over the final part of the simulations (3500-4000 hrs) All growth rates ar calculated in the presence of unlimited hydrogen gas, water, sodium, ammonium, phosphate, sulfate and protons. a Growth rate on glucose. b Growth rate on acetate. c Growth rate on CO₂. d Growth rate on formate. e Growth rate on lactate. f Growth rate on propionate
