Isolation of Pseudomonas species from soil sample for production of Pyoverdine and evaluation of its potential as an antimicrobial agent

open access: yes, 2021
Pyoverdine, a fluorescent siderophore that have high- affinity for iron is produced synthesizes it under iron-deficient growth conditions. Pseudomonas species are often encountered in diverse ecological habitats along side being censurable for nosocomial

A rhlI 5′ UTR-Derived sRNA Regulates RhlR-Dependent Quorum Sensing in Pseudomonas aeruginosa [PDF]

open access: yes, 2019
N-Acyl homoserine lactone (AHL) quorum sensing (QS) controls expression of over 200 genes in Pseudomonas aeruginosa. There are two AHL regulatory systems: the LasR-LasI circuit and the RhlR-RhlI system.

Crosstalk Between Microbiome and Ferroptosis in Diseases: From Mechanism to Therapy

open access: yesComprehensive Physiology, Volume 15, Issue 4, August 2025.
The human microbiome, a key homeostatic hub, interacts with ferroptosis in diseases. This review dissects the crosstalk between the microbiome and ferroptosis, providing strategies for disease therapy. FMT, fecal microbiota transplantation; ROS, reactive oxygen species; TCM, traditional Chinese medicine.

Succinopyoverdins - a New Variety of the Pyoverdin Chromophore

open access: yesZeitschrift für Naturforschung C, 2000
Abstract Pseudomonas spp. of the fluorescent group produce siderophores (so-called pyoverdins) consisting of a peptide chain attached to a pyrimidoquinoline ring system which is derived from a condensation product of L-Dab and D-Tyr. Commonly several related compounds are found to accompany the pyoverdins having the same peptide chain ...

Receptor uptake arrays for vitamin B12, siderophores and glycans shape bacterial communities

open access: yes, 2017
Molecular variants of vitamin B12, siderophores and glycans occur. To take up variant forms, bacteria may express an array of receptors. The gut microbe Bacteroides thetaiotaomicron has three different receptors to take up variants of vitamin B12 and 88 ...

Contribution of the Twin Arginine Translocation system to the exoproteome of Pseudomonas aeruginosa [PDF]

open access: yes, 2016
The opportunistic pathogen Pseudomonas aeruginosa uses secretion systems to deliver exoproteins into the environment. These exoproteins contribute to bacterial survival, adaptation, and virulence.

The TonB‐Dependent Transport System Facilitates the Uptake of Inorganic Metal Mediators in Pseudomonas putida KT2440 in a Bioelectrochemical System

open access: yesMicrobial Biotechnology, Volume 18, Issue 8, August 2025.
Mediator‐based extracellular electron transfer in Pseudomonas putida KT2440 relies on the TonB‐dependent system for effective mediator (ferricyanide) transport. Transcriptomic and functional analyses confirmed its key role, while OprF overexpression enhanced membrane permeability and current output. These findings clarify mediator uptake mechanisms and

Pseudomonas aeruginosa Performs Chemotaxis to All Major Human Neurotransmitters

open access: yesMicrobial Biotechnology, Volume 18, Issue 8, August 2025.
Schematic representation of the Pseudomonas aeruginosa chemoreceptors that mediate chemotaxis to ten different human neurotransmitters. Chemoeffectors in back were shown to bind directly to the dCache type ligand binding domains of the corresponding chemoreceptor.

Strengthen or Weaken: Evolutionary Directions of Cross‐Feeding After Formation

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 4, August 2025.
There are two evolutionary directions for cross‐feeding consortia after formation: strengthening and weakening. Simultaneously, cross‐feeding reshapes the focal strain evolution from niche space, selective pressure, horizontal gene transfer, and evolutionary rate.

In cellulo FRET-FLIM and single molecule tracking reveal the supra-molecular organization of the pyoverdine bio-synthetic enzymes in Pseudomonas aeruginosa

open access: yesQuarterly Reviews of Biophysics (print), 2020
The bio-synthesis of pyoverdine (PVD) in Pseudomonas aeruginosa involves multiple enzymatic steps including the action of non-ribosomal peptide synthetases (NRPSs).
