Effect of H2O2 treatment on E. chrysanthemi growth
| Strain | Area of inhibition, cm2 |
|---|---|
| 3937/pLAFR3 | 4.57 ± 0.17 |
| MEH14/pLAFR3 | 10.89 ± 1.47 |
| MEH14/pLAMS11 | 4.84 ± 0.18 |
Disks were impregnated with H2O2 (400 mM) and laid on top of bacterial lawns. The amount of growth inhibition was calculated as the area of growth inhibition minus the disk area. Experiments were made by using Ceria medium with added tetracycline and FeSO4 (50 μM). Means and standard deviation (indicated by ±) of triplicate determinations are from two independently grown cultures.
