FIG. 2.

Effect of glucose on growth of E. coli strains used in this study. Cells were grown in LB medium (A) or in LB medium plus 0.4% glucose (B) at 37°C with shaking (250 rpm) in 25 ml of medium in 250-ml Erlenmeyer flasks. These conditions are identical to those used for the transcriptome and real-time PCR experiments. Strains were as follows: triangles, wild type (BW25113); diamonds, crp mutant; squares, fur mutant; circles, crp fur double mutant.
