N-Acyl Homoserine Lactone Production by Klebsiella pneumoniae Isolated from Human Tongue Surface
Sensors, 2012 Bacteria communicate by producing quorum sensing molecules called autoinducers, which include autoinducer-1, an N-hexanoyl homoserine lactone (AHL), and autoinducer-2.

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

Acta Agriculturae Slovenica, 2007 Rumen is an example of a complex microbial ecosystem where extensive intraspecies as well as interspecies cell-cell cross-communication is expected, but little is known about. Four ruminal Prevotella strains, Prevotella bryantii B14, TC1-1 and TF1-3, and

Protein Science, Volume 35, Issue 8, August 2026.Abstract Microorganisms use diverse small‐molecule signals to coordinate behavior, supporting interspecies and interkingdom communication. These chemical dialogs shape fundamental biological processes and define interactions from cooperation to antagonism.

LuxS influencesEscherichia colibiofilm formation through autoinducer-2-dependent and autoinducer-2-independent modalities [PDF]
FEMS Microbiology Ecology, 2012 Escherichia coli produces biofilms in response to the small molecule autoinducer-2 (AI-2), a product of the LuxS enzyme. LuxS is part of the activated methyl cycle and could also affect biofilm development by AI-2-independent effects on metabolism. A luxS deletion mutant of E.

Pengaruh Herba Sambiloto (Andrographis paniculata Nees) Terhadap Autoinducer Bakteri Pseudomonas aeruginosa PAO1 Diamati dengan Sensor Bioluminescence [PDF]
, 2009 Tingkah laku bakteri diatur oleh mekanisme quorum sensing, termasuk ekspresi faktor-faktor virulensi. Mekanisme ini diperantarai oleh suatu sinyal molekul yaitu autoinducer yang diproduksi oleh bakteri itu sendiri.

Emergence of Continents Stabilized the Bioavailability of Boron
Terra Nova, Volume 38, Issue 4, Page 278-284, August 2026.ABSTRACT Boron is an essential element for the development of life on Earth; borates stabilize ribose in prebiotic reactions and facilitate metabolism in higher plants. There is, however, a relatively narrow surface boron concentration range over which borates stabilize and serve as a micronutrient rather than a toxin.
