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

Environmental 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.

Attenuated Strains of Pseudomonas aeruginosa: A Promising Cell Factory for Rhamnolipid Production

Microbial Biotechnology, Volume 18, Issue 11, November 2025.
PGN strains are generated by the deletion of virulence factor genes. The metabolic pathways and regulatory frameworks that lead to high‐efficiency production of rhamnolipids in P. aeruginosa are preserved in these strains. Therefore, PGN strains are promising bio‐safe cell factories for the industrial production of rhamnolipids.

Effects on LuxR‐Regulated Bioluminescence of Cyclodextrin‐Acyl‐L‐Homoserine Lactone Hybrids

ChemBioChem, Volume 26, Issue 19, October 3, 2025.
Cyclodextrin‐N‐acyl‐L‐Homoserine‐Lactone conjugates are synthetized, purified and fully characterized. The study of modulation of LuxR‐regulated bioluminescence production has demonstrated that one of the compounds exhibits not only the capacity to induce bioluminescence with an EC50 value of 64 µM, but also the ability to reduce bioluminescence with ...

Transcriptional reprogramming underpins enhanced plant growth promotion by the biocontrol fungus Trichoderma hamatum GD12 during antagonistic interactions with Sclerotinia sclerotiorumin soil [PDF]

, 2016
The free-living soil fungus Trichoderma hamatum strain GD12 is notable amongst Trichoderma strains in both controlling plant diseases and in stimulating plant growth, a property enhanced during its antagonistic interactions with pathogens in soil.

Ferribactins -the Biogenetic Precursors of Pyoverdins

Zeitschrift für Naturforschung C, 1991
Abstract From ferribactins which accompany pyoverdins in iron deficient cultures of fluorescent pseudomonads a subunit has been obtained formed by condensation of D-tyrosin with L-2,4-diaminobutyric acid to give 2-(1-R-amino-2-p-hydroxyphenylethyl)-1,4,5,6-tetrahydropyrimidine-4-S′-carboxylic acid (1).

Efficient Synthesis of the Pyoverdine Chromophore: Expanding the Toolbox for the Preparation of Pyoverdine Conjugates

European Journal of Organic Chemistry
AbstractThe pyoverdine chromophore is an important component of a family of siderophores which are secreted by the human pathogen Pseudomonas aeruginosa for iron absorption. In this study, an efficient and improved synthetic route to the chromophore structure is reported, beginning from readily available starting materials, D‐glutamic acid and L–DOPA ...
