Presence of the siderophores pyoverdine and pyochelin in the extracellular medium reduces toxic metal accumulation in Pseudomonas aeruginosa and increases bacterial metal tolerance.
In order to get access to iron, Pseudomonas aeruginosa strain PAO1 produces two major siderophores pyoverdine (PVD) and pyochelin (PCH). Both siderophores are able to chelate many other metals inExpand

Siderotyping--a powerful tool for the characterization of pyoverdines.
Tools for the identification of bacteria are of great importance especially for taxonomical and medical purposes. In the case of fluorescent pseudomonads a quick and unambiguous identification isExpand

Characterization of the Yersinia pestisYfu ABC Inorganic Iron Transport System
ABSTRACT In Yersinia pestis, the causative agent of plague, two inorganic iron transport systems have been partially characterized. The yersiniabactin (Ybt) system is a siderophore-dependentExpand

Identification of type II and type III pyoverdine receptors from Pseudomonas aeruginosa.
Pseudomonas aeruginosa produces, under conditions of iron limitation, a high-affinity siderophore, pyoverdine (PVD), which is recognized at the level of the outer membrane by a specificExpand

Siderophore Typing, a Powerful Tool for the Identification of Fluorescent and Nonfluorescent Pseudomonads
ABSTRACT A total of 301 strains of fluorescent pseudomonads previously characterized by conventional phenotypic and/or genomic taxonomic methods were analyzed through siderotyping, i.e., by theExpand

Yersiniabactin Production Requires the Thioesterase Domain of HMWP2 and YbtD, a Putative Phosphopantetheinylate Transferase
ABSTRACT One requirement for the pathogenesis of Yersinia pestis, the causative agent of bubonic plague, is the yersiniabactin (Ybt) siderophore-dependent iron transport system that is encoded withinExpand

Pseudomonas mosselii sp. nov., a novel species isolated from clinical specimens.
Twenty-two fluorescent pseudomonad strains of clinical origin received as Pseudomonas fluorescens (10 strains), Pseudomonasputida (10 strains) and Pseudomonas sp. (2 strains), and 33 type strains ofExpand

Metallome of Pseudomonas aeruginosa: a role for siderophores.
In this paper, we describe the total metal composition (metallome) of Pseudomonas aeruginosa. Inductively coupled plasma atomic emission spectroscopy analyses showed that P. aeruginosa cellsExpand

Effect of pyoverdine supply on cadmium and nickel complexation and phytoavailability in hydroponics
Siderophores are chelators with a high selectivity for Fe(III) and a good affinity for divalent metals, including Cd(II) and Ni(II). Inoculation with siderophore-producing bacteria (SPB) has thusExpand

FpvA-mediated ferric pyoverdine uptake in Pseudomonas aeruginosa: identification of aromatic residues in FpvA implicated in ferric pyoverdine binding and transport.
A number of aromatic residues were seen to cluster in the upper portion of the three-dimensional structure of the FpvA ferric pyoverdine receptor of Pseudomonas aeruginosa, reminiscent of theExpand
