Pseudoverdin, a Compound Related to the Pyoverdin Chromophore from a Pseudomonas aeruginosa Strain Incapable to Produce Pyoverdins [1]

Abstract From a genetically manipulated strain of Pseudomonas aeruginosa ATCC 15692 (PAO 1 strain) a compound named pseudoverdin, 3-formylamino-6,7-dihydroxycoumarin, was obtained which is related to the typical pyoverdin chromophore and thus allows to shed some light on the biogenesis of the latter.
