Prevention of biofilm formation by quorum quenching [PDF]
Applied Microbiology and Biotechnology, 2020 AbstractQuorum sensing (QS) is a mechanism that enables microbial communication. It is based on the constant secretion of signaling molecules to the environment. The main role of QS is the regulation of vital processes in the cell such as virulence factor production or biofilm formation.

High yield expression of an AHL-lactonase from Bacillus sp. B546 in Pichia pastoris and its application to reduce Aeromonas hydrophila mortality in aquaculture [PDF]
, 2010 Background Aeromonas hydrophila is a serious pathogen and can cause hemorrhagic septicemia in fish. To control this disease, antibiotics and chemicals are widely used which can consequently result in "superbugs" and chemical accumulation in the food ...

Modulation of host biology by Pseudomonas aeruginosa quorum sensing signal molecules: messengers or traitors [PDF]
, 2015 YesBacterial cells sense their population density and respond accordingly by producing various signal molecules to the surrounding environments thereby trigger a plethora of gene expression. This regulatory pathway is termed quorum sensing (QS).

Bacterial biofilms: role of quorum sensing and quorum quenching
Journal of Experimental Biology and Agricultural Sciences, 2022 Bacterial biofilms provide an adjustable strategy to manage themselves in the existing conditions. Biofilms of pathogenic bacteria act as a reservoir for various device and non-device related diseases which are tough to cure. Exposure to a high dose of antibiotics is not an appropriate solution to this problem as high antibiotic concentrations lead to ...

Signal Disruption Leads to Changes in Bacterial Community Population
Frontiers in Microbiology, 2019 The disruption of bacterial signaling (quorum quenching) has been proven to be an innovative approach to influence the behavior of bacteria. In particular, lactonase enzymes that are capable of hydrolyzing the N-acyl homoserine lactone (AHL) molecules ...
