✦ Synopsis

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 bound to a chlorinated chromophore derived from 5-chloro-2,3-diamino-6, 7dihydroxyquinolme. A mechanism for the formation of these compounds is suggested and a procedure for the preparation of halopyoverdins is described.
