Pseudomonas aeruginosa FpvB Is a High-Affinity Transporter for Xenosiderophores Ferrichrome and Ferrioxamine B

mBio, 2023
Iron is essential for many biological functions in bacteria, but its poor solubility is a limiting factor for growth. Bacteria produce siderophores, soluble natural products that bind iron with high affinity, to overcome this challenge.

Rational Design of Optical Single‐Walled Carbon Nanotube‐Based Nanosensors with Biological Recognition Elements

Advanced Sensor Research, Volume 5, Issue 3, March 2026.
This Review focuses on assessing and providing perspective on the field of rationally‐designed optical sensors constructed with single‐walled carbon nanotubes. The literature is reviewed and evaluated for SWCNT‐based sensors constructed with biomolecular recognition elements, including proteins, peptides, and oligonucleotides, as well as their methods ...

Pyoverdine synthesis by the Mn(II)-oxidizing bacterium Pseudomonas putida GB-1

Frontiers in Microbiology, 2014
When iron-starved, the Mn(II)-oxidizing bacteria Pseudomonas putida strains GB-1 and MnB1 produce pyoverdines (PVDGB-1 and PVDMnB1), siderophores that both influence iron uptake and inhibit manganese(II) oxidation by these strains.

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.

Time Kill Curve PD Modelling Experiments Are Affected by Trailing MIC Endpoints: Refinement of MIC Determination for S. pseudintermedius

Journal of Veterinary Pharmacology and Therapeutics, Volume 49, Issue 2, Page 220-227, March 2026.
ABSTRACT Trailing endpoints are a recognised challenge in broth microdilution MIC testing, particularly for bacteriostatic agents such as trimethoprim (TMP) and sulphonamides. In this study, we applied a pharmacodynamically guided refinement to determine the MIC of the combination against Staphylococcus pseudintermedius; we did not aim at redefining ...

Synthesis of the Pyoverdin Chromophore by a Biomimetic Oxidative Cyclization [PDF]

Organic Letters, 2009
The fluorescent dihydropyrimido[1,2-a]quinoline chromophore of the pyoverdin siderophores has been synthesized by a biomimetic oxidative cyclization using an iodine(III) reagent, followed by elimination and dehydrogenation.

Bacterial Fluorescence Signals Predict Dermal Regeneration Template Integration Outcomes

Wound Repair and Regeneration, Volume 34, Issue 2, March/April 2026.
ABSTRACT Acute trauma wounds with exposed bone or tendon present significant reconstructive challenges, with high rates of dermal regeneration template (DRT) failure, often due to missed infections. Standard‐of‐care wound assessment, which relies on subjective clinical signs and traditional swabbing methods, frequently fails to detect clinically ...
