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.

Detection, Characterization, and Biological Effect of Quorum-Sensing Signaling Molecules in Peanut-Nodulating Bradyrhizobia

Sensors, 2012
Bacteria of the genus Bradyrhizobium are able to establish a symbiotic relationship with peanut (Arachis hypogaea) root cells and to fix atmospheric nitrogen by converting it to nitrogenous compounds.

Relay Architectures and Ecological Strategies of Quorum Sensing Effects on Microbial Interactions

Environmental Microbiology, Volume 28, Issue 10, October 2026.
Quorum‐sensing activity in one population affects neighbouring populations through direct signal perception, QS‐regulated chemical effectors, or host‐ or environment‐mediated relays. Across distinct habitats, these relay architectures are associated with ecological strategies ranging from shared signal accessibility and reciprocal responsiveness to ...

A Rhodococcal Transcriptional Regulatory Mechanism Detects the Common Lactone Ring of AHL Quorum-Sensing Signals and Triggers the Quorum-Quenching Response

Frontiers in Microbiology, 2018
The biocontrol agent Rhodococcus erythropolis disrupts virulence of plant and human Gram-negative pathogens by catabolizing their N-acyl-homoserine lactones.

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Selection of a new Pseudomonas chlororaphis strain for the biological control of Fusarium oxysporum f. sp. radicis-lycopersici

Phytopathologia Mediterranea, 2011
Fluorescent pseudomonads possess several physiological characteristics exploitable for the biological control of phytopathogenic fungi. A group of 11 pseudomonads able to inhibit tomato pathogenic fungi in vitro were identified using the Biolog test and ...

Potential of a Quorum Quenching Bacteria Isolate Ochrobactrum intermedium D-2 Against Soft Rot Pathogen Pectobacterium carotovorum subsp. carotovorum

Frontiers in Microbiology, 2020
Quorum quenching (QQ) is a promising strategy for preventing and controlling quorum sensing (QS)-mediated bacterial infections. It interferes with QS by the inhibition of signal synthesis, the detection of enzyme-catalyzed degradation, and the ...

Phenotypic expression of the gene‐for‐gene interaction in plant pathogenic bacteria: An implication for resistance to bacterial diseases by plants

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Plant pathogenic bacteria cause massive losses in agriculture and damage to natural plant habitats. Bacterial pathogens not only reduce crop production, but they also reduce crop quality by releasing toxins into the environment. Pathogenic bacteria that invade plant tissues must overcome the plant's defense mechanisms. Plants possess an innate
