Planktonic Growth of Pseudomonas aeruginosa around a Dual-Species Biofilm Supports the Growth of Fusobacterium nucleatum within That Biofilm

Figure 6

Growth of P. aeruginosa creates anaerobic conditions within 4 h of inoculation. Fifty mL tubes of BHI broth were left uninoculated or inoculated with 10⁶ CFU PAO1 and incubated for 24 h at 37°C. Levels of DO₂ were measured at times indicated. Values represent the means of three independent experiments ± SEM; .
