Biosynthesis of H2S and Siderophores Targeting Gram‐Negative Bacterial Resistance to Reactive Oxygen Species

open access: yesAdvanced Science, Volume 12, Issue 45, December 4, 2025.
Discover how Gram‐negative bacteria develop resistance to reactive oxygen species, and how scientists aim to overcome this challenge. Abstract Reactive oxygen species (ROS) are a promising alternative bactericide. However, it is questioned that bacteria can potentially develop resistance to ROS, similar to their resistance against antibiotics and ...

Characterization of Ocular Clinical Isolates of Pseudomonas aeruginosa from Non-Contact Lens Related Keratitis Patients from South India

open access: yesMicroorganisms, 2020
P. aeruginosa is the most common Gram-negative organism causing bacterial keratitis. Pseudomonas utilizes various virulence mechanisms to adhere and colonize in the host tissue.

Quantifying the Dynamics of Bacterial Secondary Metabolites by Spectral Multiphoton Microscopy [PDF]

open access: yes, 2011
Phenazines, a group of fluorescent small molecules produced by the bacterium Pseudomonas aeruginosa, play a role in maintaining cellular redox homeostasis. Phenazines have been challenging to study in vivo due to their redox activity, presence both intra-

Metagenomic Profiling and Genome‐Centric Analysis Reveal Iron Acquisition Systems in Cheese‐Associated Bacteria and Fungi

open access: yesEnvironmental Microbiology, Volume 27, Issue 12, December 2025.
This study describes the diversity of iron acquisition systems in cheese microorganisms and provides information on the distribution of siderophore biosynthesis pathways in both bacteria and fungi, including poorly characterised species. ABSTRACT Cheese microbial communities are composed of diverse interacting microorganisms, including both inoculated ...

When genome-based approach meets the “Old but Good”: revealing genes involved in the antibacterial activity of Pseudomonas sp. P482 against soft rot pathogens [PDF]

open access: yes, 2016
Dickeya solani and Pectobacterium carotovorum subsp. brasiliense are recently established species of bacterial plant pathogens causing black leg and soft rot of many vegetables and ornamental plants. Pseudomonas sp.

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 ...

Defining the Roles of the Cation Diffusion Facilitators in Fe2+/Zn2+ Homeostasis and Establishment of Their Participation in Virulence in Pseudomonas aeruginosa [PDF]

open access: yes, 2017
Transporters of the cation diffusion facilitator (CDF) family form dimers that export transition metals from the cytosol. The opportunistic pathogen Pseudomonas aeruginosa encodes three homologous CDF genes, czcD (PA0397), aitP (PA1297), and yiiP (PA3963)

Functional Characterisation of Microbial Communities Related to Black Stain Formation in Lascaux Cave

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Excessive anthropization can lead to black stain alterations on cave walls. The present work reports the first metagenomic analysis of black stains threatening artwork in Lascaux Cave. Findings show new microbial taxa and genetic potential associated with black stains.
