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

Classifying the Topology of AHL-Driven Quorum Sensing Circuits in Proteobacterial Genomes

Sensors, 2012
Virulence and adaptability of many Gram-negative bacterial species are associated with an <em>N</em>-acylhomoserine lactone (AHL) gene regulation mechanism called quorum sensing (QS).

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.

N-acetylglucosamine inhibits LuxR, LasR and CviR based quorum sensing regulated gene expression levels

Frontiers in Microbiology, 2016
N-acetyl glucosamine, the monomer of chitin, is an abundant source of carbon and nitrogen in nature as it is the main component and breakdown product of many structural polymers. Some bacteria use N-acyl-L-homoserine lactone (AHL) mediated quorum sensing

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

Phloretin, an Apple Phytoalexin, Affects the Virulence and Fitness of Pectobacterium brasiliense by Interfering With Quorum-Sensing

Frontiers in Plant Science, 2021
The effects of phloretin a phytoalexin from apple, was tested on Pectobacterium brasiliense (Pb1692), an emerging soft-rot pathogen of potato. Exposure of Pb1692 to 0.2 mM phloretin a concentration that does not affect growth, or to 0.4 mM a 50% growth ...

Quorum sensing in the plant pathogen Erwinia carotovora subsp. carotovora [PDF]

, 2009
Erwinia carotovora subsp. carotovora (Ecc) is a Gram-negative enterobacterium that causes soft-rot in potato and other crops. The main virulence determinants, the extracellular plant cell wall -degrading enzymes (PCWDEs), lead to plant tissue maceration.

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.
