Values represent the average maximum doubling time in minutes of E. coli strains BW25113 and CSH142 under various growth conditions. Values are an average of three biological replicated ±SD. M9 represents M9 minimal medium with supplemented glucose. Δefp represents E. coli BW25113 efp::kan, whereas K42T represents CSH142 with an S12 ribosomal protein mutation K42T.
