In the course of the purification procedure of pyoverdins produced by Pseudomonas aeruginosa ATCC 15692 in large batch cultures, a minor peptidic chlorinated siderophore was isolated. This compound possesses the same peptidic moiety as the three major pyoverdins isolated from this strain, but it is
## Abstract Under iron‐deficient conditions, the Gram‐negative bacterium __Pseudomonas aeruginosa__ ATCC 15692 secretes a peptidic siderophore, pyoverdin PaA, composed of an aromatic chromophore derived from 2,3‐diamino‐6,7‐dihydroxyquinoline and a partially cyclized octapeptide, D‐Ser–L‐Arg–D‐Ser–
