FIG. 3.

Effects of expression of the cph1 and cpl1 genes on the growth of the E. coli. (A) Cultures of HB101(pNM185) (○ and •), HB101(pAMR11) (□ and ▪), and HB101(pAMR12) (▵ and ▴) that were uninduced (open symbols) or induced at time zero with 2 mM 3-MB (filled symbols). Cultures were incubated at 30°C. OD₆₀₀, optical density at 600 nm. (B) Viabilities of the same cultures obtained after plating two appropriate dilutions on LB medium.
