Synergistic Inhibitory Effect and Mechanism of Action of Cinnamaldehyde‐Carvacrol Nanoemulsion on the Staphylococcus aureus and Escherichia coli Mixed Biofilms Formation

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
The study prepared Cinnamaldehyde‐Carvacrol nanoemulsions (CA/CV NEs) through high‐energy emulsification. In a mouse infection model, CA/CV NEs exhibited a synergistic inhibitory effect on the formation of Staphylococcus aureus–Escherichia coli mixed biofilms, reducing PIA, LuxS/AI‐2, adhesion, athletic ability, and extracellular protein.

Analysis of Autoinducer-2 Quorum Sensing in Yersinia pestis [PDF]

Infection and Immunity, 2013
ABSTRACT The autoinducer-2 (AI-2) quorum-sensing system has been linked to diverse phenotypes and regulatory changes in pathogenic bacteria. In the present study, we performed a molecular and biochemical characterization of the AI-2 system in Yersinia pestis , the causative agent of plague. In strain CO92,

The intragenus and interspecies quorum-sensing autoinducers exert distinct control over Vibrio cholerae biofilm formation and dispersal.

PLoS Biology, 2019
Vibrio cholerae possesses multiple quorum-sensing (QS) systems that control virulence and biofilm formation among other traits. At low cell densities, when QS autoinducers are absent, V. cholerae forms biofilms.

Natural Genome Diversity of AI-2 Quorum Sensing in Escherichia coli: Conserved Signal Production but Labile Signal Reception [PDF]

, 2012
Quorum sensing (QS) regulates the onset of bacterial social responses in function to cell density having an important impact in virulence. Autoinducer-2 (AI-2) is a signal that has the peculiarity of mediating both intra- and interspecies bacterial QS ...

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.

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 ...

Quorum sensing in thermophiles: prevalence of autoinducer-2 system [PDF]

BMC Microbiology, 2018
Quorum sensing is a mechanism of cell to cell communication that requires the production and detection of signaling molecules called autoinducers. Although mesophilic bacteria is known to utilize this for synchronization of physiological processes such as bioluminescence, virulence, biofilm formation, motility and cell competency through signaling ...
