Involvement of Acylated Homoserine Lactones (AHLs) of Aeromonas sobria in Spoilage of Refrigerated Turbot (Scophthalmus maximus L.)

Italian National Conference on Sensors, 2016
One quorum sensing strain was isolated from spoiled turbot. The species was determined by 16S rRNA gene analysis and classical tests, named Aeromonas sobria AS7.

Quorum Sensing and Spoilage Potential of Psychrotrophic Enterobacteriaceae Isolated from Milk

BioMed Research International, Volume 2018, Issue 1, 2018., 2018
The 16S rDNA of six psychrotrophic Enterobacteriaceae isolated from cold raw milk were sequenced and the isolate 039 was identified as Pantoea sp., isolates 059, 068, and 071 were identified as Hafnia alvei, 067 was identified as Enterobacter sp., and 099 was identified as Aeromonas hydrophila.

Dinuclear Gallium(III) Complex With 1,3‐Propanediamine‐N,N′‐Diacetate: Structural Characterization, Antimicrobial Activity, and DNA/BSA Interactions

Bioinorganic Chemistry and Applications, Volume 2025, Issue 1, 2025.
In this study, a tetradentate 1,3‐propanediamine‐N,N′-diacetate (1,3‐pdda2−) was utilized for the synthesis of a dinuclear gallium(III) complex, uns‐cis‐[Ga(1,3‐pdda)(µ‐OH)]2.2H2O (1). Complex 1 was characterized using IR and NMR (1H and 13C) spectroscopy, and its crystal structure was determined by single‐crystal X‐ray diffraction analysis.

N‐Acyl Homoserine Lactone‐Mediated Quorum Sensing with Special Reference to Use of Quorum Quenching Bacteria in Membrane Biofouling Control

BioMed Research International, Volume 2014, Issue 1, 2014., 2014
Membrane biofouling remains a severe problem to be addressed in wastewater treatment systems affecting reactor performance and economy. The finding that many wastewater bacteria rely on N‐acyl homoserine lactone‐mediated quorum sensing to synchronize their activities essential for biofilm formations; the quenching bacterial quorum sensing suggests a ...

Quorum Sensing Activity of Aeromonas Caviae Strain YL12, A Bacterium Isolated from Compost

Sensors, 2014
Quorum sensing is a well-studied cell-to-cell communication method that involves a cell-density dependent regulation of genes expression mediated by signalling molecules. In this study, a bacterium isolated from a plant material compost pile was found to

CerM and Its Antagonist CerN Are New Components of the Quorum Sensing System in Cereibacter sphaeroides, Signaling to the CckA/ChpT/CtrA System

MicrobiologyOpen, Volume 13, Issue 6, December 2024.
The quorum sensing (QS) system of Cereibacter sphaeroides includes six LuxR homologs and one acylhomoserine lactone synthase homolog. Two LuxR homologs, CerM and CerN, are involved in regulating the expression of ctrA, which is part of the CckA/ChpT/CtrA two‐component system that controls flagellar motility.

Onion‐pathogenic Burkholderia species: Role and regulation of characterized virulence determinants

Plant Pathology, Volume 73, Issue 9, Page 2281-2297, December 2024.
Protein secretion systems and toxoflavin are well‐characterized virulence factors in onion‐pathogenic Burkholderia species. The tofIMR quorum‐sensing system and qsmR regulate multiple Burkholderia virulence factors. Abstract Members of the bacterial genus Burkholderia are a routine threat to onion production worldwide.

Quorum-sensing signaling is required for production of the antibiotic pyrrolnitrin in a rhizospheric biocontrol strain of Serratia plymuthica [PDF]

, 2017
One mechanism that bacteria have adopted to regulate the production of antimicrobial compounds is population-density-dependent LuxRI-type quorum sensing (QS), exploiting the production of N-acyl homoserine lactone (AHL) autoinducer signals. In biocontrol
