Quorum sensing

, 2019
Quorum sensing is the intercellular communication used by a bacterial population, once it reaches a certain threshold, to collectively synchronize the expression of pathogenic traits, such as biofilm formation, swarming motility, and the production of virulence factors. This coordinated behaviour is mediated via small molecules called auto-inducers. In

The Potential of Secondary Metabolites in Medicinal Plants as Anti–Quorum Sensing in Biofilms: A Comprehensive Review

Journal of Chemistry
The formation of biofilms occurs due to a group of bacteria gathering together. The increasing of cell density will stimulate chemical signals for bacteria to communicate through quorum sensing system.

Bio‐Inspired Gradient Coatings Enhance the Leading Edge Erosion Resistance of Wind Blades

Advanced Science, EarlyView.
Rain‐induced erosion of the wind turbine blade leading edge poses a critical challenge to maintenance and operation. Here, we propose a bio‐inspired approach for erosion protection utilising a platelet‐reinforced polyurethane coating with a graded through‐thickness architecture.

Synergy of Quorum Quenching Enzyme and Quorum Sensing Inhibitor in Inhibiting P.aeruginosa Quorum Sensing [PDF]

, 2017
ABSTRACT The threat of antibiotic resistant bacteria has called for alternative antimicrobial strategies that would mitigate the increase of classical resistance mechanism. Many bacteria employ quorum sensing (QS) to govern the production of virulence genes and formation of drug-resistance biofilms.

Drought Stress Mediated Changes in Food Crops: Mechanisms and Remediation Strategies

Advanced Science, EarlyView.
This work presents a multi‐scale framework for flavonoid‐mediated drought tolerance in staple food crops, integrating ROS redox regulation, antioxidant defense, rhizosphere microbial interactions, and sustainable agronomic practices. This interdisciplinary model provides core insights to develop climate‐resilient cropping systems and enhance global ...

TNAP and PHOSPHO1 Function Synergistically to Afford Critical Control Over the Mineralization of the Postnatal Murine Skeleton

Advanced Science, EarlyView.
Biomineralization underpins skeletal development, yet its molecular control remains incompletely understood. Using a novel murine knockout model, this study reveals the essential and complementary roles of PHOSPHO1 and TNAP in postnatal skeletal development.

Can the natural diversity of quorum sensing advance synthetic biology?

Frontiers in Bioengineering and Biotechnology, 2015
Quorum-sensing networks enable bacteria to sense and respond to chemical signals produced by neighboring bacteria. They are widespread: over one hundred morphologically and genetically distinct species of eubacteria are known to use quorum sensing to ...

Nanocrystalline LCO/LLZO Composite Cathode Films for Solid State Batteries

Advanced Energy Materials, EarlyView.
A single precursor solution is solution‐deposited and calcined at only 750°C to yield a dense, nanograined LiCoO2/LLZO composite cathode, in which both phases crystallize independently with minimal interdiffusion. Assembled into all‐solid‐state Li‐metal batteries, the composite delivers 111.7 mAh g−1 initial discharge capacity and retains 93% after 100

Research progress on the mechanisms by which plant-originated quorum sensing inhibitors inhibit pathogenic bacteria of acne

Pifu-xingbing zhenliaoxue zazhi
The main acne-causing bacteria are Propionibacterium acnes, Staphylococcus aureus and Staphylococcus epidermidis. Quorum sensing, an important factor for bacterial survival, is closely associated with expression of bacterial virulence factors and biofilm
