quorum sensing n. A phenomenon in which a population of bacteria produces and responds to intercellular chemical signals whose concentration indicates the density of the population. When the density reaches a certain level, genes are expressed that allow for coordinated group behavior, as in biolumines...

Quorum sensing is a mechanism wherein the bacteria secrete small molecules, such as N-(3-oxo-dodecanoyl)-l-homoserine lactone (3O-C12-HSL), that promote biofilm formation and interbacterial communication [158]. Quorum sensing genes in P. aeruginosa (strain PAO1) and 3O-C12-HSL attenuate ...

Postbiotics could also modulate the microbiota indirectly, for example by carrying quorum sensing and quorum quenching molecules81 or by carrying lactic acid that can be consumed by some members of the microbiota resulting in SCFAs and butyrate, which have a beneficial function82. Postbiotics can ...
