When was quorum sensing first described in bacteria?
Quick Answer
Quorum sensing was first described in the late 1960s and early 1970s. It showed that bacteria can coordinate behavior using chemical signals.
The Full Story
The phenomenon now called quorum sensing was first recognized in marine bacteria in the late 1960s and early 1970s. Scientists found that bacteria could detect their population density by sensing signaling molecules and then change gene expression accordingly. This discovery was revolutionary because it showed that bacteria behave collectively rather than only as isolated cells. Quorum sensing is now known to control processes such as bioluminescence, virulence, biofilm formation, and antibiotic production.
