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 bioluminescence or the formation of biofilms.

Biofilm formation begins when free floating planktonic bacteria reach a certain cellular density, initiating quorum sensing (QS) triggered changes in the levels of expression of fimbriae, flagella, and so forth, which allow the organism to be more easily attached to the surface.
Este estilo de vida bacteriano es una adaptacion particularmente importante para crecer como parte de una comunidad sesil, que imita a un organismo multicelular integrado con su propio ciclo de desarrollo, el comportamiento cooperativo entre las especies, y la gestion coordinada utilizando moleculas de deteccion senal quorum sensing para comunicarse entre ellos.
