Rhizobactin B is the preferred siderophore by a novel Pseudomonas isolate to obtain iron from dissolved organic matter in peatlands [PDF]

, 2020
Bacteria often release diverse iron-chelating compounds called siderophores to scavenge iron from the environment for many essential biological processes. In peatlands, where the biogeochemical cycle of iron and dissolved organic matter (DOM) are coupled,

Patient‐Specific Coculture of S. aureus and P. aeruginosa Enhances Epithelial Barrier Disruption and Virulence in CRS

International Forum of Allergy &Rhinology, Volume 16, Issue 1, Page 43-54, January 2026.
ABSTRACT Background Chronic rhinosinusitis (CRS) is a chronic inflammatory disease that is associated with polymicrobial infections, often involving S. aureus and P. aeruginosa. It is unclear whether the polymicrobial context plays a role in exacerbating epithelial damage, inflammation, and resistance to therapy. Methods S. aureus and P. aeruginosa (n =

Impact of Copper on the Physiology and Transcriptome of Methylosinus Trichosporium OB3b Grown on Either Methane or Methanol

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Methylosinus trichosporium OB3b can grow on methanol in the absence but not presence of copper due: (1) overgeneration of reducing power from methanol oxidation; (2) formate accumulation leading to acidification of the growth medium and inactivation of formate dehydrogenase; and (3) lack of expression of potential oxidative stress defence genes ...

A New Pyoverdin from Pseudomonas aeruginosa R'

Zeitschrift für Naturforschung C, 2001
Abstract From a Pseudom onas aeruginosa hospital isolate a new pyoverdin was isolated. It is iden­tical with that of Pseudomonas aeruginosa strain R except that in the peptide chain L-Gln is missing.

Specific Gene Loci of Clinical Pseudomonas putida Isolates [PDF]

, 2016
Pseudomonas putida are ubiquitous inhabitants of soils and clinical isolates of this species have been seldom described. Clinical isolates show significant variability in their ability to cause damage to hosts because some of them are able to modulate ...

Advancing the Development of Pseudomonas protegens PBL3 Secretome as a Biopesticide to Control Bacterial Panicle Blight in Rice

Plant Pathology, Volume 75, Issue 1, January/February 2026.
Pseudomonas protegens PBL3 secretome was successfully scaled up and provided effective preventive control of Bacterial Panicle Blight at the rice panicle stage, supporting its potential use as a practical, biologically based management tool. ABSTRACT Bacterial panicle blight (BPB), caused by Burkholderia glumae, is an emerging disease in rice that ...

Pseudomonas aeruginosa Biofilms in Cystic Fibrosis: Interactions, Methods, and Therapeutic Strategies

BioMed Research International, Volume 2026, Issue 1, 2026.
This review explores the role of Pseudomonas aeruginosa biofilms in cystic fibrosis (CF) pathogenesis. Biofilms, the main bacterial lifestyle in CF lungs, are key in therapy failure, immune evasion, and chronic infection persistence. This review examines biofilm structure, emphasizing extracellular polymeric substances (Psl, Pel, alginate, eDNA) and ...

Molecular Mechanisms of Plant Growth–Promoting Rhizobacteria (PGPR) in Biofertilization and Disease Suppression of Crops

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
Plant growth–promoting rhizobacteria (PGPR) are beneficial soil bacteria that colonize the rhizosphere and enhance plant growth through direct and indirect mechanisms, including nutrient solubilization, phytohormone production, suppression of phytopathogens, and activation of plant defense mechanisms.
