Intermicrobial interaction: Aspergillus fumigatus siderophores protect against competition by Pseudomonas aeruginosa.

PLoS ONE, 2019
Pseudomonas aeruginosa and Aspergillus fumigatus are pathogens frequently co-inhabiting immunocompromised patient airways, particularly in people with cystic fibrosis.

Effects of exogenous pyoverdines on Fe availability and their impacts on Mn(II) oxidation by Pseudomonas putida GB-1

Frontiers in Microbiology, 2014
Pseudomonas putida GB-1 is a Mn(II)-oxidizing bacterium that produces pyoverdine-type siderophores (PVDs), which facilitate the uptake of Fe(III) but also influence MnO2 formation.

Disruption of Pyoverdine Synthesis in Pseudomonas Aeruginosa Through Periodic Disturbance of Biofilm Structure [PDF]

, 2020
Infections due to bacteria were once easily treated using antibiotics. However, the effective shelf life of antibiotics is diminishing due to the rise and spread of antibiotic resistant bacteria.

Efficient Synthesis of the Pyoverdine Chromophore: Expanding the Toolbox for the Preparation of Pyoverdine Conjugates

European Journal of Organic Chemistry
AbstractThe pyoverdine chromophore is an important component of a family of siderophores which are secreted by the human pathogen Pseudomonas aeruginosa for iron absorption. In this study, an efficient and improved synthetic route to the chromophore structure is reported, beginning from readily available starting materials, D‐glutamic acid and L–DOPA ...

Structural and functional insights into Pseudomonas aeruginosa ApaH, a diadenosine tetraphosphatase crucial for bacterial virulence

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Infections by Pseudomonas aeruginosa are a major cause of severe morbidity and mortality in immunocompromised patients and people with cystic fibrosis, largely due to the pathogen's ability to resist antibiotic treatment and to deploy multiple virulence strategies that promote persistence in the host.

Diverse DTPA‐chelated lanthanides with relevance for nuclear medicine bound to an engineered lipocalin reveal conserved ligand geometry

Acta Crystallographica Section F, Volume 82, Issue 9, Page 301-311, September 2026.
Structural and binding studies of the engineered lipocalin CL31d towards the chelate complexes of 11 different lanthanide and main‐group metal(III) ions, whose radioisotopes are useful for nuclear medicine, with a functionalized DTPA revealed a surprisingly broad tolerance towards varying ionic radii, thus enabling flexible radionuclide‐targeting ...

Differences in Siderophore Production During the Growth of Phytoplankton in Southern Ocean Incubation Experiments Under High‐ and Low‐Iron Conditions

Environmental Microbiology, Volume 28, Issue 9, September 2026.
Experiments performed in the Southern Ocean under low‐ and high‐iron conditions showed that the heterotrophic bacteria community produced distinct iron‐binding compounds called siderophores, depending on the environmental conditions, despite similar bacteria communities being present in each experiment.

Draft genomes and initial characterization of siderophore producing pseudomonads isolated from mine dump and mine drainage

Biotechnology Reports, 2020
Siderophores are of high interest for biotechnological, pharmaceutical, agricultural and industrial applications. Although they are synthesized by various organisms, the yield is usually low which hindrances their suitability for broad range uses.
