FIG. 4.
Analysis of zwf transcription (A) and G6PDH activity (B) throughout a normal aerobic growth phase. Wild-type bacteria and strains PAO9011 (zwf::lacZ-Gmr, sense orientation) and PAO9012 (zwf::lacZ-Gmr, antisense orientation) were grown aerobically at 37°C in L broth. At intervals, organisms were harvested and specific activities for β-galactosidase and G6PDH were measured. •, OD600; ▵, β-galactosidase specific activity of strain PAO9011; ○, G6PDH activity.
