Pyoverdine, the yellow‐green fluorescent pigment produced by Pseudomonas aeruginosa, is a highly efficient siderophore. Pyoverdine‐deficient (pvd) mutants of P. aeruginosa PAO isolated after mutagenesis were non‐fluorescent and unable to grow in the presence of 2.8 mM ethylenediamine‐di‐(o‐hydroxyphenylacetate) (EDDHA). Addition of purified pyoverdine to media containing EDDHA restored growth of pvd mutants. 6 pvd mutations were mapped between catA and mtu‐9002 (at 65–70 min on the chromosome map) by R68.45‐mediated conjugation. 2 slightly leaky pvd mutations were localised between argC and strA (at 35 min) by transduction. Thus, we have identified at least 2 genes or gene clusters required for pyoverdine production in P. aeruginosa.

Iron uptake and detection of an outer membrane iron-siderophore receptor protein from Pseudomanas aeruginosa PA01

Under iron‐restricted conditions, Pseudomonas aeruginosa PA01 produced large amounts of the fluorescent pigment, pyoverdine, which is a siderophore of this organism. Maximum iron uptake was found in P. aeruginosa PA01 only in the presence of its own pyoverdine and not in those from other Pseudomonas species, suggesting species specificity of pyoverdine for ion uptake. An iron‐binding protein (60 000 mol.wt.) present in outer membranes of iron‐restricted cultures was absent from iron‐supplemented cultures.
