Quorum sensing is a regulatory system used by bacteria for controlling gene expression in response to increasing cell density. Different quorum sensing molecules are produced at different times in bacterial population growth and have distinct cellular effects mediated through changes in gene expression. N-3-hydroxyoctanoyl-L-Homoserine lactone is a small diffusible signaling molecule secreted by various bacteria. This lactone can have activating or suppressing effects on gene expression and biofilm formation, respectively. N-3-hydroxyoctanoyl-L-Homoserine lactone is produced via lactonolysis from 3-oxooctanoyl-homoserine lactone, altering quorum sensing or contributing to quorum quenching.

Candidates of quorum sensing bacteria in activated sludge associated with N-acyl homoserine lactones
Chemosphere 2019 Dec;236:124292.PMID:31310968DOI:10.1016/j.chemosphere.2019.07.023.
This study aimed to explore candidates of microbial groups which is associated with quorum sensing in activated sludge. Activated sludge samples were collected from three wastewater treatment plants (WWTP) to analyze N-acyl homoserine lactone (AHL) by Fourier-transform mass spectrometry (FTMS) and 16S rRNA-based microbial community. Among activated sludge samples taken at 3 WWTPs in different seasons, 2 AHL species of N-3-hydroxyoctanoyl-L-Homoserine lactone and N-3-hydroxydecanoyl-l-homoserine lactone were detected in the range of ranged of 0.1 ng/L to 1.6 ng/L. The detected AHL species were not dependent on treatment systems nor seasons. From microbial community analysis, population abundance of one strain in Verrucomicrobia and two strains in Holophagaceae had high correlation with AHL concentration in activated sludge. Comamonadaceae had also moderately correlated population with AHL concentrations among quorum sensing bacteria reported previously.
