FromPseudomonassp. CFML 95Ð275 a pyoverdin was isolated with a cyclopeptidic sub- structure. It could be shown that this pyoverdin is identical with one obtained fromPseudom- onas fluorescensBTP 7 for which a lactone structure had been deduced from the interpreta- tion ofa FAB spectrum. The elucidation ofthe correct structure ofthe pyoverdin is described.
