Gram-negative bacterial communication by N-acyl homoserine lactones: a universal language?

Trends in Microbiology, 1994
The ability of bacterial cells to use small signalling molecules to monitor population growth may help them to react rapidly to environmental change. Regulatory systems made up of a small sensor molecule, an N-acyl homoserine lactone and a protein effector have been identified recently in a wide range of Gram-negative bacteria.

High-Performance Liquid Chromatography Analysis of N-Acyl Homoserine Lactone Hydrolysis by Paraoxonases

2010
Mammalian paraoxonases (PONs) are a unique, highly conserved family of calcium-dependent esterases consisting of PON1, PON2, and PON3. The PONs can hydrolyze the lactone ring of a range of N-acyl-L: -homoserine lactone (AHL) quorum sensing signaling molecules, rendering them inactive.

Quorum-sensing molecules N-acyl homoserine lactones inhibit Trueperella pyogenes infection in mouse model

Veterinary Microbiology, 2018
Trueperella pyogenes is a gram-positive opportunistic pathogen normally causes mastitis, liver abscesses and pneumonia of economically important livestock. It has been suggested that gram-negative bacteria can suppress the growth and virulence of T.

The role of N-acyl homoserine lactones in maintaining the stability of aerobic granules

Bioresource Technology, 2014
In this study, porcine kidney acylase, as N-acyl homoserine lactones (AHLs)-degradation enzyme, was employed for the first time to directly investigate the role of AHLs in the structure stability of aerobic granules. Results clearly showed that inactivation of AHLs by AHLs-acylase could weaken the stability of aerobic granule.

Inactivation of bacterial quorum sensing signals N-acyl homoserine lactones is widespread in yeasts

Fungal Biology, 2018
The inactivation of quorum sensing signals, a phenomenon known as quorum quenching, has been described in diverse microorganisms, though it remains almost unexplored in yeasts. Beyond the well-known properties of these microorganisms for the industry or as eukaryotic models, the role of yeasts in soil or in the inner tissues of a plant is largely ...

Triazole-containing N-acyl homoserine lactones targeting the quorum sensing system in Pseudomonas aeruginosa

Bioorganic & Medicinal Chemistry, 2015
In an attempt to devise new antimicrobial treatments for biofilm infections, the bacterial cell-cell communication system termed quorum sensing has emerged as an attractive target. It has proven possible to intercept the communication system by synthetic non-native ligands and thereby lower the pathogenesis and antibiotic tolerance of a bacterial ...

Candidates of quorum sensing bacteria in activated sludge associated with N-acyl homoserine lactones

Chemosphere, 2019
This study aimed to explore candidates of microbial groups which is associated with quorum sensing in activated sludge. Activated sludge samples were collected from three wastewater treatment plants (WWTP) to analyze N-acyl homoserine lactone (AHL) by Fourier-transform mass spectrometry (FTMS) and 16S rRNA-based microbial community.

[Isolation and identification of Rhodosporidium toruloides R1 degrading N-acyl homoserine lactone].

Wei sheng wu xue bao = Acta microbiologica Sinica, 2009
In the present study, a AHL-utilizing strain RI was isolated and identified as the genus Rhodosporidium toruloides R1 by physi-biochemical approaches and 18S rDNA sequence analysis, and this strain was designated as R. toruloides R1. Results showed that R.
