Characterisation of a Marine Bacterium Vibrio Brasiliensis T33 Producing N-acyl Homoserine Lactone Quorum Sensing Molecules

Sensors, 2014
N-acylhomoserine lactones (AHL) plays roles as signal molecules in quorum sensing (QS) in most Gram-negative bacteria. QS regulates various physiological activities in relation with population density and concentration of signal molecules. With the aim

Determination of N-acylhomoserine lactones of Pseudomonas aeruginosa in clinical samples from dogs with otitis externa [PDF]

BMC Veterinary Research, 2016
Bacterial intercellular communication, called quorum sensing, takes place via the production and collective response to signal molecules. In Gram-negative bacteria, like Pseudomonas aeruginosa, these signaling molecules are N-acylhomoserine lactones (AHLs). P. aeruginosa is a common cause of inflammation of the ear canal (otitis externa) in dogs.

Identification of Quorum-Sensing Signal Molecules and a Biosynthetic Gene in Alicycliphilus sp. Isolated from Activated Sludge

Sensors, 2016
Activated sludge is a complicated mixture of various microorganisms that is used to treat sewage and industrial wastewater. Many bacteria produce N-acylhomoserine lactone (AHL) as a quorum-sensing signal molecule to regulate the expression of the ...

Short Chain N-acyl Homoserine Lactone Production by Soil Isolate Burkholderia sp. Strain A9

Sensors, 2013
In the bacteria kingdom, quorum sensing (QS) is a cell-to-cell communication that relies on the production of and response to specific signaling molecules. In proteobacteria, N-acylhomoserine lactones (AHLs) are the well-studied signaling molecules.

A novel metagenomic short-chain dehydrogenase/reductase attenuates Pseudomonas aeruginosa biofilm formation and virulence on Caenorhabditis elegans. [PDF]

PLoS ONE, 2011
In Pseudomonas aeruginosa, the expression of a number of virulence factors, as well as biofilm formation, are controlled by quorum sensing (QS). N-Acylhomoserine lactones (AHLs) are an important class of signaling molecules involved in bacterial QS and ...

N-Acylhomoserine lactone-dependent cell-to-cell communication and social behavior in the genus Serratia

International Journal of Medical Microbiology, 2006
Members of the genus Serratia are increasingly responsible for nosocomial infections, the treatment of which may be complicated by the appearance of multi-antibiotic-resistant strains. Some but not all Serratia strains and species produce N-acylhomoserine lactones (AHLs), and possess luxR and luxI homologous genes.

Degradation of Bacterial Quorum Sensing Signaling Molecules by the Microscopic Yeast Trichosporon loubieri Isolated from Tropical Wetland Waters

Sensors, 2013
Proteobacteria produce N-acylhomoserine lactones as signaling molecules, which will bind to their cognate receptor and activate quorum sensing-mediated phenotypes in a population-dependent manner.

Quorum sensing in Aeromonas hydrophila and Aeromonas salmonicida: identification of the LuxRI homologs AhyRI and AsaRI and their cognate N-acylhomoserine lactone signal molecules

Journal of Bacteriology, 1997
Spent culture supernatants from both Aeromonas hydrophila and Aeromonas salmonicida activate a range of biosensors responsive to N-acylhomoserine lactones (AHLs).

Distribution of N-Acylhomoserine Lactone-Producing Fluorescent Pseudomonads in the Phyllosphere and Rhizosphere of Potato (Solanum tuberosum L.).

Microbes and Environments, 2009
Four hundred and fifty nine isolates of fluorescent pseudomonads were obtained from the leaves and roots of potato plants. Of these, 20 leaf isolates and 28 root isolates induced violacein production in two N-acylhomoserine lactone (AHL)-reporter strains-Chromobacterium violaceum CV026 and VIR24.
