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 ...

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 ...

Quorum quenching–Stören friede zwischenbakterieller Beziehungen
BIOspektrum, 2016Most bacteria are able to grow in biofilms in which they effectively resist antimicrobial agents. This leads to a general problem, since traditional treatments of bacteria and prevention strategies become mostly ineffective. Novel strategies for biofilm inhibition are thus urgently required.

Quorum Quenching in Anti-virulence Therapy
2023The quest for new anti-virulence medications has been sparked by the rising antibiotic resistance rates of pathogenic bacteria. By interfering with vital components of bacteria, such as their cell walls, nucleic acids and protein biosynthesis, conventional antibiotics kill or restrict bacterial growth.

Quorum Quenching Applications in Plant Biotechnology
2023Quorum sensing is a signal transmission and recognition system used by bacterial cells for several biochemical and physiological functions, including pathogenicity, and is significant in resisting the plant immune system. While the molecules and the chemical reactions involved vary among different classes of bacteria, the system involves a molecule ...

Quorum Quenching Compounds from Natural Sources
2017Quorum sensing is a process of bacterial communication system wherein the production and secretion of small signaling molecules known as autoinducers enables the bacteria to express specific genes at particular population densities. Quorum quenching (QQ) can be used as an alternative approach to regulate pathogenicity.

Quorum Quenching Strategy Targeting Gram-Positive Pathogenic Bacteria
2016Quorum sensing (QS) is a cell density-dependent regulatory system that orchestrates the group behavior of unicellular organisms by synchronizing the expression of certain gene(s) within the clonal community of same species. Bacterial pathogens often employ QS system to establish efficiently an infection.

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.
