Abstract excerpt
Pseudomonas aeruginosa has two siderophore-based high-affinity iron-uptake systems utilizing pyoverdin and pyochelin. Using strain IA1, a mutant deficient in production of both siderophores, we have shown that addition of purified siderophore to the growth medium induces expression of specific iron-regulated outer-membrane proteins and increases 55Fe-siderophore transport. Addition of pyoverdin from the parent...
