Quorum sensing and its 11 importances

quorum sensing

According to Rutherford, S. T., & Bassler, B. L., quorum sensing is a process of cell–cell communication. It allows bacteria to share information about cell density and adjust gene expression accordingly.

Quorum sensing occurs in response to extracellular signaling molecules called autoinducers.

These autoinducers are acylated homoserine lactones in gram negative bacteria. On the other hand, processed oligopeptides are these signaling molecules.
