Quorum-quenching enzymes: Promising bioresources and their opportunities and challenges as alternative bacteriostatic agents in food industry.

Comprehensive Reviews in Food Science and Food Safety, 2023
The problems of spoilage, disease, and biofilm caused by bacterial quorum-sensing (QS) systems have posed a significant challenge to the development of the food industry.

Generation of Quorum Quenching Antibodies

2010
The exchange of information within and among bacterial populations using small diffusible molecules has been termed "quorum sensing" (QS). Due to the extracellular distribution of the QS autoinducer molecules and the evolutionary highly conserved nature of signaling components, microbial QS systems represent an excellent target for anti-infective ...

Quorum Quenching in Membrane Bioreactors for Fouling Retardation: Complexity Provides Opportunities.

Environmental Science and Technology
The occurrence of biofouling restricts the widespread application of membrane bioreactors (MBRs) in wastewater treatment. Regulation of quorum sensing (QS) is a promising approach to control biofouling in MBRs, yet the underlying mechanisms are complex ...

Exploring an Efficient and Eco-Friendly Signaling Molecule and Its Quorum Quenching Ability for Controlling Microcystis Blooms.

Environmental Science and Technology, 2023
Globally, cyanobacterial blooms have become serious problems in eutrophic water. Most previous studies have focused on environmental factors but have neglected the role of quorum sensing (QS) in bloom development and control.

Quorum Quenching for Sustainable Environment

2021
Quorum quenching is the process that prevents quorum sensing through the disruption of signalling cascade and bacterial communication among themselves mediated by the degradation of the signalling molecules. Therefore, quorum quenching has a considerable contribution in the negative regulation of threatening diseases and eventually increasing soil ...

Quorum quenching and proactive host defense

Trends in Plant Science, 2003
Both plants and humans have inducible defense mechanisms. This passive defense strategy leaves the host unprotected for a period of time until resistance is activated. Moreover, many bacterial pathogens have evolved cell-cell communication (quorum-sensing) mechanisms to mount population-density-dependent attacks to overwhelm the host's defense ...

Quorum sensing and quorum-quenching enzymes.

Journal of microbiology (Seoul, Korea), 2005
To gain maximal benefit in a competitive environment, single-celled bacteria have adopted a community genetic regulatory mechanism, known as quorum sensing (QS). Many bacteria use QS signaling systems to synchronize target gene expression and coordinate biological activities among a local population.

Quorum Sensing and Quorum Quenching in Soil Ecosystems

2010
Several bacteria originating from soil ecosystems have evolved the ability to regulate gene expression as a function of their cell density, a phenomenon called quorum sensing (QS). To do so bacteria communicate via the production and sensing of signal molecules. The most common class of signals clusters N-acyl homoserine lactones (AHL) molecules.

Quorum Quenching: Impact and Mechanisms

2014
This chapter focuses on the impact and molecular mechanisms of quorum quenching, with emphasis on quorum-quenching enzymes and other signal disruption mechanisms. There are five key processes in quorum-sensing circuit, (i) signal generation, (ii) signal transportation, (iii) signal accumulation, (iv) signal recognition, and (v) signal autoinduction ...

Synergistic Quorum quenching activity of Cinnamaldehyde against biofilm forming Pseudomonas aeruginosa

Research journal of biotechnology
Quorum sensing is an essential mechanism for the pathogenesis of Pseudomonas aeruginosa, which causes opportunistic infections in humans. Quorum sensing inhibition has been considered a unique strategy to treat opportunistic infections and prevent an ...
