Biotechnological applications of quorum quenching enzymes

Chemico-Biological Interactions, 2017
Numerous bacteria use quorum sensing (QS) to synchronize their behavior and monitor their population density. They use signaling molecules known as autoinducers (AI's) that are synthesized and secreted into their local environment to regulate QS-dependent gene expression. Among QS-regulated pathways, biofilm formation and virulence factor secretion are

Does quorum quenching matter to microbial community dynamics in long-term membrane bioreactor operation?

Water Research, 2023
Quorum quenching (QQ) has effectively prevented biofouling in membrane bioreactors (MBRs) employing isolated QQ bacterial strains. However, the influence of QQ on the microbial population still needs to be fully understood.

Role of quorum sensing and quorum quenching in anaerobic digestion: A scoping review.

Environmental Research, 2023
Anaerobic 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

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 enzymes

Journal of Biotechnology, 2015
Bacteria use cell-to-cell communication systems based on chemical signal molecules to coordinate their behavior within the population. These quorum sensing systems are potential targets for antivirulence therapies, because many bacterial pathogens control the expression of virulence factors via quorum sensing networks.

Quorum Quenching

2023
Antibiotic resistance is a global health concern. Strains of pathogenic microorganisms that have developed resistance to multiple antibiotics, such as MRSA, are extremely difficult to treat, and alternative methods for tackling pathogenic microorganisms are in demand.

Disrupting the bacterial language: quorum quenching and its applications

Critical reviews in microbiology
Quorum sensing (QS) is a bacterial communication method closely linked with population density and regulates biofilm formation and the secretion of virulence factors through the release, recognition, and prompt response to small molecule signals.

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 ...

Deciphering the potential role of quorum quenching in efficient aerobic denitrification driven by a synthetic microbial community.

Water Research
Low efficiency is one of the main challenges for the application of aerobic denitrification technology in wastewater treatment. To improve denitrification efficiency, a synthetic microbial community (SMC) composed of denitrifiers Acinetobacter baumannii ...
