N-Acyl-Homoserine Lactone Quorum Sensing Switch from Acidogenesis to Solventogenesis during the Fermentation Process in Serratia marcescens MG1.

Journal of Microbiology and Biotechnology, 2019
N-acyl-homoserine lactone quorum sensing (AHL-QS) has been shown to regulate many physiological behaviors in Serratia marcescens MG1. In the current study, the effects of AHL-QS on the biosynthesis of acid and neutral products by S.

Inhibitors of Bacterial Swarming Behavior

Chemistry – A European Journal, Volume 26, Issue 5, Page 964-979, January 22, 2020., 2020
Hard to stop: Bacterial swarming motility is a form of coordinated population behavior which is important for pathogenicity and antibiotic resistance. Consequently, controlling swarming is of major interest for targeting bacterial pathogens and achieving better understanding of microbial motility.

Regulation of an antibiotic resistance efflux pump by quorum sensing and a TetR-family repressor in Chromobacterium subtsugae

bioRxiv, 2023
The soil bacterium Chromobacterium substugae uses a single LuxI-R-type quorum-sensing system, CviI-R, to regulate genes in a cell density-dependent manner. CviI synthesizes the signal N-hexanoyl-homoserine lactone (C6-HSL) and CviR is a C6-HSL-responsive

Peptides as quorum sensing molecules : measurement techniques and obtained levels in vitro and in vivo [PDF]

, 2017
The expression of certain bacterial genes is regulated in a cell-density dependent way, a phenomenon called quorum sensing. Both Gram-negative and Gram-positive bacteria use this type of communication, though the signal molecules (auto-inducers) used by ...

Combination of bacterial N-acyl homoserine lactones primes Arabidopsis defenses via jasmonate metabolism [PDF]

, 2023
N-acyl homoserine lactones (AHLs) are important players in plant–bacteria interactions. Different AHL-producing bacteria can improve plant growth and resistance against plant pathogens.

A Sinorhizobium meliloti-specific N-acyl homoserine lactone quorum-sensing signal increases nodule numbers in Medicago truncatula independent of autoregulation [PDF]

, 2016
N-acyl homoserine lactones (AHLs) act as quorum sensing signals that regulate cell-density dependent behaviors in many gram-negative bacteria, in particular those important for plant-microbe interactions.

Mechanism of the Quorum-Quenching Lactonase (AiiA) from Bacillus thuringiensis. 1. Product-Bound Structures†‡ [PDF]

, 2008
: The N-acyl-L-homoserine lactone hydrolases (AHL lactonases) have attracted considerable attention because of their ability to quench AHL-mediated quorum-sensing pathways in Gram-negative bacteria and because of their relation to other enzymes in the ...

Identification of N-acyl-l-homoserine lactones produced by non-pigmented Chromobacterium aquaticum CC-SEYA-1T and pigmented Chromobacterium subtsugae PRAA4-1T

3 Biotech, 2011
Many members of the genus Chromobacterium produce violacein, a characteristic purple pigment which is induced by small diffusible N-acyl homoserine lactones (AHL) quorum-sensing molecules.

Anti-quorum sensing evaluation of methyleugenol, the principal bioactive component, from the Melaleuca bracteata leaf oil

Frontiers in Microbiology, 2022
Quorum sensing (QS) is a cell-to-cell communication in bacteria that couples gene expression through the accumulation of signaling molecules, which finally induce the production of several virulence factors and modulate bacterial behaviors.
