Natural Lactone‐Based Quorum Sensing Inhibitors Attenuate Virulence in Pseudomonas aeruginosa

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Targeting bacterial communication, lab‐generated lactones (Lx) inhibited biofilm formation and eliminated mature biofilms within 24–48 h. Lx treatment also suppressed pyocyanin and rhamnolipid production while downregulating rhlR expression, highlighting their promise as potent quorum‐sensing (QS) inhibitors and next‐generation antibiofilm therapeutics.

Liposomal Encapsulation of Damson Plum Phenolics and Their Incorporation Into Functional Milk Beverages

Food Frontiers, Volume 7, Issue 5, September 2026.
Damson plum phenolic extract was encapsulated in soy lecithin‐based liposomes, followed by freeze‐drying and incorporation into milk. The liposomal delivery system improved the retention and recovery of key phenolic compounds, including neochlorogenic acid, rosmarinic acid, and rutin, during 28 days of refrigerated storage at 4°C, demonstrating a ...

Characterization by electrospray ionization and tandem mass spectrometry of rhamnolipids produced by two Pseudomonas aeruginosa strains isolated from Brazilian crude oil [PDF]

, 2012
In this work, biosurfactants produced by two Pseudomonas aeruginosa strains isolated from Brazilian crude oils were identified by proton nuclear magnetic resonance ((1)H NMR) and further characterized by mass spectrometry (MS) coupled with electrospray ...

Rhamnolipids: Why and how are they Produced?

, 2019
Known for more than 60 years and among the best studied biosurfactants, rhamnolipids comprise a diverse group of mono- and di-sugar amphiphilic glycolipids with surface-active properties.

Kinetic analysis and modeling of the liquid–liquid conversion of emulsified di‐rhamnolipids by Naringinase from Penicillium decumbens

Biotechnology and Bioengineering, 2008
AbstractThe enzymatic conversion of an aggregate‐forming substrate was kinetically analyzed and a model was applied for the prediction of reaction‐time courses. An L‐rhamnose molecule from a di‐rhamnolipid is cleaved by Naringinase from Penicillium decumbens leading to a mono‐rhamnolipid.

Oligoribonuclease mediates high adaptability of P. aeruginosa through metabolic conversion

BMC Microbiology
Background Oligoribonuclease (orn) of P. aeruginosa is a highly conserved exonuclease, which can regulate the global gene expression levels of bacteria through regulation of both the nanoRNA and c-di-GMP.
