A new class of Acyl-homoserine lactone quorum sensing signals
Nippon Saikingaku Zasshi, 2013 Bacteria are known to regulate various gene expressions producing particular signal molecules termed "Auto-inducers" in the cell density-dependent manner. This physiological phenomenon termed "Quorum Sensing" has been discovered in many bacteria including normal bacterial flora and pathogens.

, 2014 The acyl-homoserine lactone (AHL) autoinducer mediated quorum sensing regulates virulence in several pathogenic bacteria. The hallmark of an efficient quorum sensing system relies on the tight specificity in the signal generated by each bacterium.

Diversity and acyl-homoserine lactone production among subtidal biofilm-forming bacteria [PDF]
, 2008 Bacteria isolated from subtidal biofilms were identified via 16S rRNA gene sequencing and screened for acyl-homoserine lactone (AHL) production. In total, 68 strains were isolated from 1 to 9 d-old subtidal biofilms developed at a coastal fish farm ...

Immunity, Inflammation and Disease, Volume 14, Issue 10, October 2026.Schematic overview of the gut–skin axis highlighting how intestinal microbiota and gut‐derived signaling influence skin homeostasis through effects on barrier integrity, immune regulation, and enteroendocrine communication. Dysregulation of these pathways may contribute to skin barrier dysfunction, altered sebaceous and keratinocyte activity, and ...

Microbiology Spectrum, 2023 Bacteria need to be isolated in pure culture to gain access to the wide array of interesting functions they conceal. This is challenging because they do not live in isolation but instead in communities where they actively communicate and interact with ...

Rapid Acyl-Homoserine Lactone Quorum Signal Biodegradation in Diverse Soils [PDF]
Applied and Environmental Microbiology, 2005 ABSTRACT Signal degradation impacts all communications. Although acyl-homoserine lactone (acyl-HSL) quorum-sensing signals are known to be degraded by defined laboratory cultures, little is known about their stability in nature. Here, we show that acyl-HSLs are biodegraded in soils sampled from diverse U.S.

Frontiers in Plant Science, 2014 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.

Methods for Detecting N-Acyl Homoserine Lactone Production in Acinetobacter baumannii. [PDF]
Methods Mol Biol, 2019 Acinetobacter baumannii cell-cell signaling is mediated by production and release of N-acyl homoserine lactones (AHLs), primarily N-(3-hydroxydodecanoyl)-L-homoserine lactone (3-hydroxy-C12-HSL). The secretion of this signal can be readily assessed via simple plate-based or thin-layer chromatography-based assays utilizing an Agrobacterium tumefaciens ...

From Rhizosphere to Resistance: Microbe‐Plant Interactions in Eco‐Smart Biocontrol
MicrobiologyOpen, Volume 15, Issue 5, October 2026.Conceptual framework of eco‐smart biocontrol: Root exudates released by plants shape rhizosphere microbial community assembly by selectively recruiting beneficial microorganisms. These microbes suppress phytopathogens through direct mechanisms such as antibiosis, parasitism, enzyme production, and niche competition, while simultaneously activating ...
