Definitions for quorum sensing
This page provides all possible meanings and translations of the word quorum sensing
A proposed method of communication between bacterial cells by the release and sensing of small diffusible signal molecules.
Quorum sensing is a system of stimulus and response correlated to population density. Many species of bacteria use quorum sensing to coordinate gene expression according to the density of their local population. In similar fashion, some social insects use quorum sensing to determine where to nest. In addition to its function in biological systems, quorum sensing has several useful applications for computing and robotics. Quorum sensing can function as a decision-making process in any decentralized system, as long as individual components have: a means of assessing the number of other components they interact with and a standard response once a threshold number of components is detected.
U.S. National Library of Medicine
A phenomenon where microorganisms communicate and coordinate their behavior by the accumulation of signaling molecules. A reaction occurs when a substance accumulates to a sufficient concentration. This is most commonly seen in bacteria.
