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.

Centesimal Composition, Bioactive Compounds, and Antimicrobial Properties of White (Hylocereus undulatus) and Red (Hylocereus polyrhizus) Pitayas

Journal of Food Science, Volume 91, Issue 3, March 2026.
ABSTRACT This study investigated the centesimal composition, physicochemical properties, bioactive compounds, antimicrobial activity, and anti‐quorum sensing (QS) potential of red pulp (RP; Hylocereus polyrhizus) and white pulp (WP; Hylocereus undulatus) pitayas.

Less is more: the lack of autoinducer-2-dependent quorum sensing promotes competitive fitness of Escherichia coli strain 83972

Frontiers in Cellular and Infection Microbiology
Autoinducer-2 is a signaling molecule involved in quorum sensing in Escherichia coli. Quorum sensing enables coordinated behavior based on cell density and helps bacteria adapt to their environment.

Cooperation and competition shape ecological resistance during periodic spatial disturbance of engineered bacteria

Scientific Reports, 2017
Cooperation is fundamental to the survival of many bacterial species. Previous studies have shown that spatial structure can both promote and suppress cooperation.

Mean-field equation for a stochastic many-particle model of quorum-sensing microbial populations

, 2018
We prove a mean-field equation for the dynamics of quorum-sensing microbial populations. In the stochastic many-particle process, individuals of a population produce public good molecules to different degrees.

Single cell analysis of Vibrio harveyi uncovers functional heterogeneity in response to quorum sensing signals

BMC Microbiology, 2012
Background Vibrio harveyi and closely related species are important pathogens in aquaculture. A complex quorum sensing cascade involving three autoinducers controls bioluminescence and several genes encoding virulence factors. Single cell analysis of a V.
