Natural Products Inhibit Bacterial Growth and Modulate Quorum‐Sensing Systems Las and Rhl in Pseudomonas aeruginosa PA14

Chemistry &Biodiversity, Volume 22, Issue 12, December 2025.
ABSTRACT Quorum sensing (QS) is a bacterial cell communication system in Pseudomonas aeruginosa, which regulates the production of several virulence factors, including pyocyanin, exoproteases, and biofilm formation. Natural products (NPs) have demonstrated their ability to control QS in different bacteria. This work evaluated the antimicrobial and anti‐

Sophorolipid biosurfactants: Possible uses as antibacterial and antibiofilm agent. [PDF]

, 2015
Biosurfactants are amphipathic, surface-active molecules of microbial origin which accumulate at interfaces reducing interfacial tension and leading to the formation of aggregated micellular structures in solution.

Why do microorganisms produce rhamnolipids? [PDF]

World Journal of Microbiology and Biotechnology, 2011
We review the environmental role of rhamnolipids in terms of microbial life and activity. A large number of previous research supports the idea that these glycolipids mediate the uptake of hydrophobic substrates by bacterial cells. This feature might be of highest priority for bioremediation of spilled hydrocarbons.

Indole‐Acetic Acid Impairs Pseudomonas aeruginosa Virulence and Alters Lung Infection in Mice

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Screening for anti‐virulence activity exerted by tryptophan catabolites on laboratory and clinical strains of Pseudomonas aeruginosa showed that Indoleacetic acid (IAA) inhibits motility and pigment production, downregulates PQS gene expression, while increases oxidative stress sensitivity.

A New Way to Use Hydrophobic Deep Eutectic Solvents: Improved Lead Detection Using an Ion‐Selective Electrode with a Polymer Membrane Modified by them

ChemPhysChem, Volume 26, Issue 21, November 5, 2025.
First use of hydrophobic deep eutectic solvents (HDESs) in the preparation of polymeric membrane lead‐sensitive ion‐selective electrodes is presented. It is found that enrichment of the membrane with HDES additive improves the electrode's parameters, primarily lowering the detection limit and increasing selectivity.
