Fig. 2. Effect of oxygen on growth of P. gingivalis strains.

Fig. 2

P. gingivalis parental W83 (W83) and SigH-deficient mutant (V2948) were inoculated in BHI media and grown anaerobically (Panel A) as well as in the presence of oxygen (6% of oxygen) (Panel B). Bacterial growth was monitored by measuring optical density of the cultures at 660 nm. Means and standard deviations from two experiments are shown.
