DOI: 10.1002/cbic.201900024
Abstract: Quorum quenching lactonases are enzymes capable of hydrolyzing lactones, including N‐acyl homoserine lactones (AHLs). AHLs are molecules known as signals in bacterial communication dubbed quorum sensing. Bacterial signal disruption by lactonases was previously reported to… read more here.

DOI: 10.1007/s12602-018-9495-7
Abstract: Quorum sensing, bacterial cell-to-cell communication via small signaling molecules regulates virulence in many bacterial pathogens, and is a promising target for antivirulence therapy, which may inhibit virulence rather than cell growth and division. Herein, Bacillus… read more here.

DOI: 10.1007/s13762-018-1930-5
Abstract: Intercellular bacterial communication process via exchange of signalling molecules acyl homoserine lactone results in various group activities like bioluminescence, antibiotic production, biofilm formation, sporulation, and virulence. The signalling molecules are targeted, and the communication is… read more here.
