Fig. 6

Growth curves of methionine-auxotrophE. coli in spent medium of each strain. (A) Illustration of the experimental scheme used to evaluate methionine level in the medium following the growth of each strain. (B) Growth curves in medium from DG strains. (C) Growth curves in medium from CM strains. All curves show the growth of the auxotroph E. coli ΔmetAB in fresh MOPS minimal medium supplemented with spent and filtered medium following the growth of the indicated strains
