Organic Nanoparticles in Food Systems as Antimicrobial Agents: Synthesis Strategies, Functional Properties, and Biofilm Inhibition Mechanisms

Nano Select, Volume 7, Issue 4, April 2026.
Organic nanoparticles (ONPs) derived from biopolymers provide sustainable antimicrobial platforms with tunable physicochemical properties. By enabling controlled delivery of bioactive compounds, ONPs disrupt microbial membranes, induce oxidative stress, and inhibit quorum sensing.

Interpopulation Signaling via N-Acyl-Homoserine Lactones among Bacteria in the Wheat Rhizosphere

Molecular Plant-Microbe Interactions, 1998
The biological control bacterium Pseudomonas aureofaciens 30-84 utilizes an N-acyl-homoserine lactone (AHL) signal molecule to control phenazine antibiotic production in the wheat rhizosphere (D. W. Wood and L. S. Pierson III, Gene 168:49-53, 1996).

Cultivation‐Based Detection of a Novel High‐GC Nitrospira Derived From the Argentinian Copahue Volcano Area

Environmental Microbiology, Volume 28, Issue 4, April 2026.
In this cultivation‐based study, two novel moderately thermophilic Nitrospira enrichments were obtained from the geothermal field Las Máquinas in the Neuquén Province, Argentina. Both nitrite oxidizers, belonging to lineage V or the novel taxonomic lineage VIII, contain quorum‐sensing genes and a high genome GC content of 60.6% and 69.4%.

Non-antibiotic quorum sensing inhibitors acting against N-acyl homoserine lactone synthase as druggable target [PDF]

, 2014
YesN-acylhomoserine lactone (AHL)-based quorum sensing (QS) is important for the regulation of proteobacterial virulence determinants. Thus, the inhibition of AHL synthases offers non-antibiotics-based therapeutic potentials against QS-mediated bacterial

Molecular Mechanisms of Algicidal Bacteria in Controlling Harmful Algal Blooms: Advances in Bacteria‐Algae Interactions

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This review elucidates the molecular mechanisms of algicidal bacteria, highlighting critical behaviours like chemotaxis, quorum sensing and extracellular vesicle release. It details how these actions disrupt algal cellular integrity, photosynthesis and calcium homeostasis, providing a theoretical foundation for controlling harmful algal blooms ...

Interference with the germination and growth of Ulvazoospores by quorum-sensing molecules from Ulva-associated epiphytic bacteria [PDF]

, 2013
Ulva zoospores preferentially settle on N-acylhomoserine lactone (AHL) producing marine bacterial biofilms. To investigate whether AHL signal molecules also affect the success and rate of zoospore germination in addition to zoospore attraction, the ...
