| Isolate | Mean enzyme activity (U/mg of protein) ± SEMa
|
|
|---|---|---|
| Catalase | SOD | |
| DLC21 | 39 ± 1 | 29 ± 2 |
| DLC22 | 285 ± 8 | 77 ± 10 |
| DLC23 | 343 ± 8 | 129 ± 12 |
Data are for triplicate samples. At the onset of log phase (5 h), cultures were supplemented with 9.5 μM pyocyanin.
