Comparison of simualtion results of butyrate kinetics with Shinto’s model under Zhao et al ’s conditions A is the simulation results of butyrate kinetics based on our new model under Zhao et al.’s conditions. B is the simulation results of butyrate kinetics based on Shinto’s model under Zhao et al.’s conditions. The data spots are concentrations. The metric unit of the vertical axis in A and B is mM; and the unit of lateral axis is hr. In A and B, A is more consistent with the observation of butyrate in Zhao et al.’s experiment (Figure 2D). The figure shows that our simulated curve of butyrate kinetics is more accurate than the one produced by Shinto’s model, both in quantity scale and shape.
