Emergent Biosynthetic Capacity in Simple Microbial Communities

Figure 3

Temporal dynamics obtained by our framework for the mono-cultures and co-culture of the toy ecosystem illustrated in Figure 2.

(A) Growth rate of the red and blue species in mono-cultures and co-culture. (B) The concentration of various metabolites in the medium over time in the mono-cultures and co-culture. Metabolite Y was identified as an emergent metabolite since it was secreted in co-culture (solid line) but was totally absent from either of the two mono-cultures (dashed lines). In contrast, metabolites W and C were observed in the medium in at least one of the mono-cultures (although at different concentrations than in co-culture).
