The characterization of a new stabilized lactonase from the endophytic fungi Aspergillus pseudonomiae with anti‐bacterial and anti‐fungal properties

Protein Science, Volume 35, Issue 8, August 2026.
Abstract Microorganisms use diverse small‐molecule signals to coordinate behavior, supporting interspecies and interkingdom communication. These chemical dialogs shape fundamental biological processes and define interactions from cooperation to antagonism.

Frequency modulation of a bacterial quorum sensing response

Nature Communications, 2022
Quorum-sensing bacteria produce and secrete autoinducers that trigger a behavioral change in the population when reaching a certain threshold. Here, Bettenworth et al.

Caenorhabditis elegans Senses Bacterial Autoinducers [PDF]

Applied and Environmental Microbiology, 2006
ABSTRACT Pseudomonas aeruginosa uses virulence factors controlled by quorum sensing (QS) to kill Caenorhabditis elegans . Here we show that C.

Computational Study of Quorum Quenching of N-Acyl Homoserine Lactones by Ion Pairing to Cations [PDF]

, 2022
Biofilms are the default state of microbial life and their formation on surfaces influences many processes. The coordinated behavior of microorganisms including their growth into biofilms occurs through a process termed quorum sensing during which they ...

Emergence of Continents Stabilized the Bioavailability of Boron

Terra Nova, Volume 38, Issue 4, Page 278-284, August 2026.
ABSTRACT Boron is an essential element for the development of life on Earth; borates stabilize ribose in prebiotic reactions and facilitate metabolism in higher plants. There is, however, a relatively narrow surface boron concentration range over which borates stabilize and serve as a micronutrient rather than a toxin.

Analysing the integrated quorum sensing (iqs) system and its potential role in Pseudomonas aeruginosa pathogenesis

Frontiers in Cellular and Infection Microbiology
Since its discovery, Quorum Sensing (QS), a form of bacterial communication, has been the focus of numerous studies aimed at unravelling the mechanisms behind this intricate process.

Cyclic Dipeptides Mediating Quorum Sensing and Their Biological Effects in Hypsizygus Marmoreus

Biomolecules, 2020
A novel quorum sensing (QS) system was discovered in Serratia odorifera, the symbiotic bacterium of Hypsizygus marmoreus. This system uses cyclo(Pro-Phe), cyclo(Pro-Tyr), cyclo(Pro-Val), cyclo(Pro-Leu), cyclo(Tyr-Leu), and cyclo(Tyr-Ile) as autoinducers.

MexEF-OprN efflux pump exports the Pseudomonas quinolone signal (PQS) precursor HHQ (4-hydroxy-2-heptylquinoline). [PDF]

PLoS ONE, 2011
Bacterial cells have evolved the capacity to communicate between each other via small diffusible chemical signals termed autoinducers. Pseudomonas aeruginosa is an opportunistic pathogen involved, among others, in cystic fibrosis complications. Virulence

Development of Quorum Sensing Modulators of Streptococcus constellatus

ChemBioChem, Volume 27, Issue 13, 14 July 2026.
Using a rational design approach, novel Streptococcus constellatus competence stimulating peptide (CSP) analogs with enhanced potencies were developed. These newly identified CSP analogs provide a rational framework for the development of CSP‐based quorum sensing modulators with translational potential in attenuating virulence processes in this ...
