Autoinducer-2 Quorum Sensing Contributes to Regulation of Microcin PDI in Escherichia coli [PDF]
Frontiers in Microbiology, 2017 The Escherichia coli quorum sensing (QS) signal molecule, autoinducer-2 (AI-2), reaches its maximum concentration during mid-to-late growth phase after which it quickly degrades during stationary phase.
