Structural Basis of Acyl-homoserine Lactone-Dependent Signaling [PDF]
Acyl-homoserine lactones are small neutral lipid molecules that bacteria in the Proteobacteria group use to sense and signal their cell density. This signaling process, known as quorum sensing, activates differentiation to diverse community oriented lifestyles within the bacterial population.

Acyl Homoserine Lactone Production of Brewery Process Surface Bacteria [PDF]
The aim of this study was to find out whether the first bacterial colonizers of brewery process surfaces after washing produce acyl homoserine lactone (AHL) quorum sensing signalling molecules. Microbial attachment and biofilm formation was studied by mounting sterile uncoated and coated stainless steel coupons onto critical places of the filling ...

Plant growth-promoting bacteria (PGPB) have received great interest in recent decades. However, PGPB mechanisms remain poorly understood in forage species. We aimed to evaluate roots endophytic and rhizospheric bacteria strains from Brachiaria humidicola

Acyl-Homoserine Lactone Quorum Sensing in the Roseobacter Clade [PDF]
Members of the Roseobacter clade are ecologically important and numerically abundant in coastal environments and can associate with marine invertebrates and nutrient-rich marine snow or organic particles, on which quorum sensing (QS) may play an important role.

A Comparative Analysis of Acyl‐Homoserine Lactone Synthase Assays [PDF]
AbstractQuorum sensing is cell‐to‐cell communication that allows bacteria to coordinate attacks on their hosts by inducing virulent gene expression, biofilm production, and other cellular functions, including antibiotic resistance. AHL synthase enzymes synthesize N‐acyl‐l‐homoserine lactones, commonly referred to as autoinducers, to facilitate quorum ...

Quorum sensing systems regulate gene expression in response to bacterial population density. Acyl-homoserine lactones are a class of quorum sensing molecules found in cattle rumen that are thought to regulate the gene expression of enterohemorrhagic ...

Synthesis and analysis of stable isotope-labelled N-acyl homoserine lactones [PDF]
Aliphatic aldehydes were deuterated at the alpha-position via a base-catalyzed exchange reaction with D2O. These deuterated building blocks were used for the synthesis of labelled analogues of quorum sensing signal molecules belonging to the three major ...

Acyl Homoserine Lactones Induce Early Response in the Airway [PDF]
AbstractAcyl homoserine lactones (AHLs) are intercellular signaling molecules used in quorum sensing by Gram‐negative bacteria. We studied the early effects on the rat airway of in vivo intratracheal administration of AHLs (i.e., P. aeruginosa and B. cepacia) to test the hypothesis that AHLs also act on the airway cells, modifying secretory mechanisms ...

We report the production and degradation of quorum sensing N-acyl-homoserine lactones by bacteria isolated from Malaysian montane forest soil. Phylogenetic analysis indicated that these isolates clustered closely to the genera of Arthrobacter, Bacillus ...
