Effect of oxygen concentration on P. aeruginosa growth rates.
| Oxygen concentration | Doubling timea |
|---|---|
| 20% | 36 ± 0.8 |
| 2% | 46 ± 2 |
| 0.4% | 138 ± 20 |
| 0% | No growth |
| 0% + 100 mM KNO3 | 92 ± 11 |
Doubling time in min; determined from cultures grown in duplicate on three different days.
