Figure 1

Steady state behavior of the crossfeeding model. (a) Fractional population of strain as a function of the ratio of the two metabolite secretion rates for . (b) Number of cells in the coculture as a function of the secretion rate. (c) Regions I, II, and III for different values of and . The model parameters used were cells/mL [7],  hr−1 [8], amino acids/cell [6, 7], and  hr−1 [6, 7].
