FIG. 5.

Relationship between initiation mass and exponential growth rate. Initiation mass expressed as OD₄₆₀ units of culture mass per oriC (a) and as total protein in amino acid residues per oriC (b) as a function of the growth rate is illustrated. The media and symbols used are as described in the legend to Fig. 3. Open symbols, succinate medium; solid symbols, other media. aa, amino acids; Prot., protein.
