SMOX and cystic fibrosis: Data from these experiments show that viable PAO1 and LESB65 populations were maintained in all media for at least three days, with mid exponential growth of bacteria occurring at ~1×108 CFU/ml (Figure 1), similar to the findings of Palmeret al. for growth ofP. aeruginosa in CF sputum.21 PAO1 was able to grow to a higher density in CF sinus and lung media than in either of the equivalent conditions in health.
