Pseudomonas siderophores: production, spectrophotometry detection and Botrytis suppression

Notulae Scientia Biologicae
Siderophores are iron-chelating agents produced by almost all microorganisms in response to iron deficiency. Due to the requirement of iron for cell growth and metabolism, siderophore-mediated acquisition of iron plays a central role in determining the ...

Élucidation des mécanismes adaptatifs et métaboliques de Bacillus subtilis sur la plante et en présence d’espèces compétitrices [PDF]

, 2023
La conception de modèles réductionnistes pour étudier les interactions entre les plantes et les microbes ainsi qu’entre les microbes eux-mêmes ont permis d’élucider une multitude de mécanismes moléculaires, choses quasi impossibles en conditions ...

Mitochondria and Neuromast Tagging With Fluorescent Gallium‐Triapine Analogues: In Cellulo MP FLIM and Zebrafish Live Imaging

Advanced Science, EarlyView.
Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...

Mise en évidence de l’impact des sidérophores dans l’immunité des plantes et évaluation du potentiel clinique des conjugués antibiotiques-sidérophores [PDF]

, 2020
Les bactéries peuvent être à la fois nos amies et nos ennemies. Nos amies parce qu’elles nous assistent de plusieurs manières : par exemple dans la digestion de nourritures ainsi que dans le renforcement de notre système immunitaire.

FASLG Derived from Fibroblasts in Hydroxyapatite‐Rich Microenvironment Induces Urothelial Anoikis to Trigger Randall's Plaque Exposure

Advanced Science, EarlyView.
Randall's plaques (RP) serve as the nidus for calcium oxalate (CaOx) kidney stones. The current study reveals that hydroxyapatite (HAP) crystals activate the THY1–GSK3α/β–β‐catenin axis in renal interstitial fibroblasts (hRIFs), inducing FASLG secretion.

Mechanistic insights into a novel exporter-importer system of Mycobacterium tuberculosis unravel its role in trafficking of iron. [PDF]

PLoS ONE, 2008
Elucidation of the basic mechanistic and biochemical principles underlying siderophore mediated iron uptake in mycobacteria is crucial for targeting this principal survival strategy vis-à-vis virulence determinants of the pathogen.

Scale‐up of Streptomyces species cultivations based on the morphological response to the energy dissipation rate

AIChE Journal, EarlyView.
Abstract Filamentous microorganisms exhibit complex morphologies that influence product formation and are affected by various bioprocess parameters. Consistent morphology is therefore essential for comparable results during scale‐up. This study investigates the scale‐up of Streptomyces species (Streptomyces spp.) cultivations from shake flasks to ...

Le biofilm de Bacillus Subtilis : un élément central dans la gestion de son homéostasie du fer [PDF]

, 2020
Le fer est un des éléments les plus importants pour les organismes vivants. Très abondant dans le sol et pourtant peu biodisponible il est devenu une ressource stratégique pour la majorité des organismes, dont les bactéries, car il est impliqué dans de ...
