Figure 8

Bifurcation diagrams of a model for tryptophan regulation in Escherichia coli. Bifurcation diagrams of the tryptophan regulation model (14) in Escherichia coli described in [11] with dilution rate μas bifurcation parameter. The system shows two Hopf bifurcations at {\mu }_1^{\ast }=0.02486 and {\mu }_2^{\ast }=0.1529. Has been created with Additional file 5.
