Vibriobactin transport at high EDDA concentrations requires the Viu proteins in V. choleraea
| Indicator strain | Genotype or phenotype | Zone of stimulation (mm) with:
|
|
|---|---|---|---|
| Lou15 | Ferrichrome | ||
| Lou15 | Wild type | 14 | 15 |
| EWV103 | viuP | 0 | 12 |
| EWV103/pVIB147 | ViuP+ | 9 | 15 |
| SSV121 | viuG | 0 | 11 |
| SSV121/pVIB147 | ViuG+ | 15 | 16 |
Cultures of the indicator strains were seeded into L agar containing 1 mg of EDDA per ml. V. cholerae Lou15 or ferrichrome was spotted onto the medium. The zone of growth was measured 18 h after inoculation.
