Quorum-sensing molecules: Sampling, identification and characterization of -acyl-homoserine lactone in sp.

Quorum sensing (QS) is a mechanism by which gram-negative bacteria regulate their gene expression by making use of cell density. QS is triggered by a small molecule known as an autoinducer. Typically, gram-negative bacteria such as produce signaling molecules called acyl homoserine lactones (AHLs).
