Plant‐Derived Extracts Disrupt Biofilm Formation and Quorum Sensing in Yersinia enterocolitica: Insights From GC‐MS and Molecular Docking

Food Chemistry International, EarlyView.
The graphical abstract represents how natural plant products that preferentially target the specific receptors of quorum sensing could be developed to combat biofilms linked to Yersinia enterocolitica using the potent abilities of protein–ligand complexes with high docking scores.

Structural and Functional Siderophore Remodeling by Enzymatic Delipidation

Angewandte Chemie, Volume 138, Issue 39, 21 September 2026.
A surprising functional switch in bacterial siderophores was discovered through genome mining and the analysis of environmental and pathogenic Pandoraea species. Pandorachelin B, a lipocyclopeptide that promotes swarming motility, is cleaved by a specialized acylase, yielding a ring‐contracted, homodetic cyclopeptide, pandorachelin A, which exhibits ...

Discovery of Pantoea rodasii Strain ND03 that Produces N-(3-Oxo-hexanoyl)-L-homoserine Lactone

Sensors, 2014
Proteobacteria use quorum sensing to regulate target gene expression in response to population density. Quorum sensing (QS) is achieved via so-called signalling molecules and the best-studied QS signalling system uses N-acyl homoserine lactones (AHLs ...

IgE‐Binding Bacterial Components Not Yet Documented in the Allergen Databases and Their Allergenic Mechanisms: An EAACI Position Paper

Allergy, EarlyView.
ABSTRACT Among bacteria that are associated with the development and/or exacerbation of allergic/atopic diseases, several have been described to produce IgE‐binding components. However, only one bacterial protein, Bac s 1, is currently listed in the official database of the World Health Organization/International Union of Immunological Societies (WHO ...

Presence of acyl‐homoserine lactones in 57 members of theVibrionaceaefamily [PDF]

Journal of Applied Microbiology, 2013
The aim of this study was to use a sensitive method to screen and quantify 57 Vibrionaceae strains for the production of acyl-homoserine lactones (AHLs) and map the resulting AHL profiles onto a host phylogeny.We used a high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) protocol to measure AHLs in spent media after bacterial ...

Advances in Spatial Heterogeneity and Cellular Localization Specificity of Intratumoral Bacteria

Cancer Science, EarlyView.
Spatial localization of intratumoral bacteria governs their functional roles in tumor progression, metastasis, and treatment responses, with guiding significance for clinical management, as reviewed across three spatial paradigms. ABSTRACT Bacteria in tumors are increasingly recognized to be a part of the tumor microenvironment and their biological ...

N-Acyl Homoserine Lactones in Diverse Pectobacterium and Dickeya Plant Pathogens: Diversity, Abundance, and Involvement in Virulence

Sensors, 2012
Soft-rot bacteria Pectobacterium and Dickeya use N-acyl homoserine lactones (NAHSLs) as diffusible signals for coordinating quorum sensing communication.

Beyond Bactericidal: Plasma Surface Engineering to Defeat Food Matrix‐Conditioning Layers

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 6, November 2026.
ABSTRACT The persistence of foodborne pathogens on industrial food contact surfaces continues to challenge global food safety despite advances in sanitation technologies. A central limitation of current antimicrobial strategies lies in their validation under simplified laboratory conditions that overlook the physicochemically driven formation of food ...

Enzymatic Assays to Investigate Acyl-Homoserine Lactone Autoinducer Synthases [PDF]

, 2017
Bacteria use chemical molecules called autoinducers as votes to poll their numerical strength in a colony. This polling mechanism, commonly referred to as quorum sensing, enables bacteria to build a social network and provide a collective response for fighting off common threats.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, Volume 600, Issue 20, Page 2981-3008, October 2026.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?
