Exploiting quorum sensing interfering strategies in gram-negative bacteria for the enhancement of environmental applications [PDF]
Frontiers in Microbiology, 2016 Quorum sensing (QS) is a widespread intercellular form of communication to coordinate physiological processes and cooperative activities of bacteria at the population level, and it depends on the production, secretion, and detection of small diffusible ...

Quorum sensing in Vibrio fischeri: probing autoinducer-LuxR interactions with autoinducer analogs [PDF]
Journal of Bacteriology, 1996 The Vibrio fischeri luminescence genes are activated by the transcription factor LuxR in combination with a diffusible signal compound, N-(3-oxohexanoyl) homoserine lactone, termed the autoinducer. We have synthesized a set of autoinducer analogs. Many analogs with alterations in the acyl side chain showed evidence of binding to LuxR.

Attenuation of Pseudomonas aeruginosa Virulence by Pomegranate Peel Extract
Microorganisms, 2022 Pseudomonas aeruginosa is an opportunistic pathogen often responsible for biofilm-associated infections. The high adhesion of bacterial cells onto biotic/abiotic surfaces is followed by production of an extracellular polysaccharidic matrix and formation ...

Quorum Sensing Interfering Strategies and Their Implications in the Management of Biofilm-Associated Bacterial Infections [PDF]
Brazilian Archives of Biology and Technology, 2020 The bacterial species employ various types of molecular communication systems recognized as quorum sensing for the synchronization of differential gene expression to regulate virulence traits and biofilm formation. A variety of quorum sensing inhibitors;

Core Principles of Bacterial Autoinducer Systems [PDF]
Microbiology and Molecular Biology Reviews, 2015 SUMMARY Autoinduction (AI), the response to self-produced chemical signals, is widespread in the bacterial world. This process controls vastly different target functions, such as luminescence, nutrient acquisition, and biofilm formation, in different ways and integrates additional environmental and physiological cues.
