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.

Exploring Naturally Tailored Bacterial Outer Membrane Vesicles for Selective Bacteriostatic Implant Coatings

Advanced Science, Volume 11, Issue 39, October 23, 2024.
Bacterial outer membrane vesicles (OMVs) are now used to construct implant coatings, showing unexpected selective bacteriostasis at the macroscopic level. Using a simple polyphenol bridging technology stabilizes bacterial OMVs on various implant surfaces. This OMVs coating gives implants the ability to selectively inhibit bacteria. This method provides

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.

From trade‐off to synergy: microbial insights into enhancing plant growth and immunity

Plant Biotechnology Journal, Volume 22, Issue 9, Page 2461-2471, September 2024.
Summary The reduction in crop yield caused by pathogens and pests presents a significant challenge to global food security. Genetic engineering, which aims to bolster plant defence mechanisms, emerges as a cost‐effective solution for disease control. However, this approach often incurs a growth penalty, known as the growth‐defence trade‐off.

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 ...

Flavonoids, gut microbiota, and host lipid metabolism

Engineering in Life Sciences, Volume 24, Issue 5, May 2024.
Abstract Flavonoids are widely distributed in nature and have a variety of beneficial biological effects, including antioxidant, anti‐inflammatory, and anti‐obesity effects. All of these are related to gut microbiota, and flavonoids also serve as a bridge between the host and gut microbiota. Flavonoids are commonly used to modify the composition of the

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.

Isolation and identification of N-acylhomoserin lactone degrading bacteria from potato rhizosphere

African Journal of Microbiology Research, 2011
In many Gram-negative bacteria, including a number of pathogens such asPectobacterium carotovorum, virulence factor production and many functions are linked to the quorum sensing (QS) systems that use diffusible N-acyl homoserine lactones (AHLs) as intercellular messenger molecules.

N-acylhomoserine lactone regulation of adhesion and biofilm differentiation in Serratia marcescens MG1

, 2004
Serratia marcescens is an opportunistic pathogen involved in predominantly nosocomial infections, however, it is also implicated as a common cause of microbial keratitis. Since many S. marcecens strains are also resistant to multiple antibiotics, this organism represents a growing public health problem. S.
