Nanomaterials Regulate Bacterial Quorum Sensing: Applications, Mechanisms, and Optimization Strategies

Advanced Science, Volume 11, Issue 15, April 17, 2024.
This review focuses on the specific mechanisms by which nanomaterials regulate bacterial quorum sensing in the signal supply and signal transduction cascade processes. Furthermore, based on the influencing factors of nanomaterial itself and environment, optimization strategies to enhance the QS regulatory activity are comprehensively summarized.

Potential of the quorum‐quenching and plant‐growth promoting halotolerant Bacillus toyonensis AA1EC1 as biocontrol agent

Microbial Biotechnology, Volume 17, Issue 3, March 2024.
Bacillus toyonensis AA1EC1 promotes plant growth and protects plants against phytopathogenic bacteria through quorum quenching mechanisms based on the enzymatic degradation of AHLs. Abstract The use of fertilizers and pesticides to control plant diseases is widespread in intensive farming causing adverse effects together with the development of ...

Sodium houttuyfonate affects production of N-acyl homoserine lactone and quorum sensing-regulated genes expression in Pseudomonas aeruginosa

Frontiers in Microbiology, 2014
Quorum sensing (QS) is a means of cell-to-cell communication that uses diffusible signaling molecules that are sensed by the population to determine population density, thus allowing co-ordinate gene regulation in response to population density.

A rhlI 5′ UTR-Derived sRNA Regulates RhlR-Dependent Quorum Sensing in Pseudomonas aeruginosa [PDF]

, 2019
N-Acyl homoserine lactone (AHL) quorum sensing (QS) controls expression of over 200 genes in Pseudomonas aeruginosa. There are two AHL regulatory systems: the LasR-LasI circuit and the RhlR-RhlI system.

Roles of ATP-dependent N-acylhomoserine lactones (AHLs) and extracellular polymeric substances (EPSs) in aerobic granulation

Chemosphere, 2012
Aerobic granules which form through a cell-to-cell self-immobilization process have been intensively studied and developed for wastewater biotreatment. However, the microbiological origin of this phenomenon is still largely unknown. This study investigated the possible role of metabolic energy in the development of aerobic granules. Results showed that

Deciphering Physiological Functions of AHL Quorum Quenching Acylases

Frontiers in Microbiology, 2017
N-Acylhomoserine lactone (AHL)-acylase (also known as amidase or amidohydrolase) is a class of enzyme that belongs to the Ntn-hydrolase superfamily. As the name implies, AHL-acylases are capable of hydrolysing AHLs, the most studied signaling molecules ...

PvdQ Quorum Quenching Acylase Attenuates Pseudomonas aeruginosa Virulence in a Mouse Model of Pulmonary Infection [PDF]

, 2018
Pseudomonas aeruginosa is the predominant pathogen in pulmonary infections associated with cystic fibrosis. Quorum sensing (QS) systems regulate the production of virulence factors and play an important role in the establishment of successful P ...

Pseudomonas aeruginosa lasI/rhlI quorum sensing genes promote phagocytosis and aquaporin 9 redistribution to the leading and trailing regions in macrophages

Frontiers in Microbiology, 2015
Pseudomonas aeruginosa controls production of its virulence factors and biofilm development via the quorum sensing (QS) system. QS signals also interact with and affect the behavior of eukaryotic cells.
