Fig 6. Biofilm growth simulation for bi-bacterial biofilm with independence or competition model.

Mean of 100 simulations in blue line with green star for the hours of experimental measurements, dotted lines for curves of minimum and maximum values, red diamonds for experimental data, initial proportion corresponding to the initialization of the mono-bacterial biofilms (36% for P. gingivalis: $N_0^{\left(1\right)}=144$, $N_0^{\left(2\right)}=261$): (a) P. gingivalis and S. gordonii independent, (b) P. gingivalis and S. gordonii in competition for nutrient.
