Quorum Quenching for Sustainable Environment
2021Quorum 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 ...

Role of quorum sensing and quorum quenching in anaerobic digestion: A scoping review
Environmental Research, 2023Anaerobic digestion (AD) is a biological process that employs anaerobic microorganisms to degrade organic material, yielding biogas and biofertilizers. Understanding quorum sensing (QS) signaling in mixed microbial systems provides valuable insights into microbial behavior and functions. This review aims to examine recent studies on the roles of QS and

Quorum Sensing and Quorum Quenching Facebook of Microbial World
International Journal of Scientific Research, 2012Dental Plaque is an example of biofilm leading to periodontal disease and dental caries. Many Gram-positive and Gram-negative bacteria communicate using small diffusible signal molecules called autoinducers. This process, known as quorum sensing, links cell density to the expression of genes as diverse as those associated with virulence fac- tors ...

Quorum sensing and quorum-quenching enzymes.
Journal of microbiology (Seoul, Korea), 2005To 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 quenching and proactive host defense
Trends in Plant Science, 2003Both 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 ...

Current Opinion in Pharmacology, 2013
With the emergence of microbial pathogens increasingly resistant against commonly used antibiotics, new treatment strategies are desperately needed. Bacterial quorum sensing has attracted a lot of attention over the last decade as a potential new target for antimicrobial therapy.

Biofouling Control by Quorum Quenching
2015Bacteria above a threshold cell density regulate the expression of a specific group of their genes in response to small signal molecules called autoinducers. This twitter communication phenomenon is called quorum sensing (QS). Among the various genetic expressions mediated by QS , biofilm formation and expression of virulence factors are the most ...

Signal Molecule-Dependent Quorum-Sensing and Quorum-Quenching Enzymes in Bacteria
Critical Reviews in Eukaryotic Gene Expression, 2014The quick spread of nosocomial bacterial infections and the increasing prevalence of drugresistant strains make the development of novel drugs for pathogens an urgent priority. Quorum sensing (QS) is a communication mechanism used by bacteria to recognize population density fluctuations and control gene expression, which play a critical role both in ...

Quorum Quenching: Impact and Mechanisms
2014This 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 ...
