Utilization of siderophores by RN6390 and H287
| Siderophore | Growth promotiona in:
|
|
|---|---|---|
| RN6390 | H287 | |
| Ferrichrome | ++++ | − |
| Aerobactin | ++++ | − |
| Desferal | ++++ | − |
| Rhodotorulic acid | − | − |
| Enterobactin | ++++ | ++++ |
| 2,3-DHBA | ++++ | ++++ |
| Pyoverdine | − | − |
| Pyochelin | − | − |
| Cepabactin | − | − |
| RN6390 siderophore(s)b | ++++ | ++++ |
++++, very good growth promotion; −, no growth promotion.
Uncharacterized siderophore(s) extracted from the culture supernatant of iron-starved RN6390.
