Phytochemical Composition, In Vitro Antioxidant, Antibacterial, and Antibiofilm Activities of Thymus vulgaris Essential Oil From Tiaret, Algeria

Chemistry &Biodiversity, Volume 23, Issue 8, August 2026.
Thymus vulgaris essential oil (TvEO), largely composed of thymol, showed strong bactericidal activity with Staphylococcus aureus (S. aureus) being most sensitive. TvEO markedly inhibited MRSA biofilm formation and significantly reduced established biofilms. Molecular docking suggests several TvEO components interact with proteins involved in S.

Pengaruh Bawang Putih (Allium sativum L.) Terhadap Autoinducer Bakteri Pseudomonas aeruginosa PAO1 Diamati dengan Sensor Bioluminescence [PDF]

, 2009
Bakteri dapat berkomunikasi satu dengan yang lain menggunakan suatu sinyal molekul kecil yang disebut autoinducer. Bila jumlah autoinducer sudah mencapi quorum, maka bakteri dapat mengatur dan mengaktifkan berbagai proses-proses penting termasuk produksi

Spatial quorum sensing modelling using coloured hybrid Petri nets and simulative model checking

BMC Bioinformatics, 2019
Background Quorum sensing drives biofilm formation in bacteria in order to ensure that biofilm formation only occurs when colonies are of a sufficient size and density.

Targeting Bacterial Communication: Evaluating Phytochemicals as LuxS Inhibitors to Disrupt Quorum Sensing

Macromol
Bacterial quorum sensing (QS) is a critical communication process that regulates gene expression in response to population density, influencing activities such as biofilm formation, virulence, and antibiotic resistance.

Where antibiotic resistance mutations meet quorum-sensing

Microbial Cell, 2014
We do not need to rehearse the grim story of the global rise of antibiotic resistant microbes. But what if it were possible to control the rate with which antibiotic resistance evolves by de novo mutation?

Proteome analysis of virulence factor regulated by autoinducer-2-like activity in Escherichia coli O157:H7

, 2016
Many pathogenic bacteria, including Escherichia coli O157:H7, can control gene expression in a cell density-dependent manner by producing small signaling molecules (autoinducers) in a process known as quorum sensing.

Interference With Quorum-Sensing Signal Biosynthesis as a Promising Therapeutic Strategy Against Multidrug-Resistant Pathogens

Frontiers in Cellular and Infection Microbiology, 2019
Faced with the global health threat of increasing resistance to antibiotics, researchers are exploring interventions that target bacterial virulence factors.

Norepinephrine may promote the progression of Fusobacterium nucleatum related colorectal cancer via quorum sensing signalling

Virulence
Fusobacterium nucleatum (F. nucleatum) is closely correlated with tumorigenesis in colorectal cancer (CRC). We aimed to investigate the effects of host norepinephrine on the carcinogenicity of F. nucleatum in CRC and reveal the underlying mechanism.

Production and properties of an inhibitor of the Pseudomonas autoinducer by Pseudomonas aeruginosa

, 2005
An inhibitor was found in the culture fluid of Pseudomonas aeruginosa PAO1. which could inhibit the activity of the Pseudomonas autoinducer (PAI). The maximal inhibitory activity occurred in stationary phase culture supernatant. The PAI inhibitor did not

Effects of vitamin B12 supply on cellular processes of the facultative vitamin B12 consumer Vibrio campbellii

Applied and Environmental Microbiology
Vitamin B12 (cobalamin, herein B12) is a key cofactor for most organisms being involved in essential metabolic processes. In microbial communities, B12 is often scarce, largely because only few prokaryotes can synthesize B12 de novo and are thus ...
