Detectable quorum signaling molecule via PANI-metal oxides nanocomposites sensors [PDF]
Scientific ReportsThe detection of N-hexanoyl-l-homoserine lactone (C6-HSL), a crucial signal in Gram-negative bacterial communication, is essential for addressing microbiologically influenced corrosion (MIC) induced by sulfate-reducing bacteria (SRB) in oil and gas ...

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

Improvement in calcified anaerobic granular sludge performance by exogenous acyl-homoserine lactones
Ecotoxicology and Environmental Safety, 2021 Given the high content of Ca2+ in waste paper recycling wastewater, the anaerobic granular sludge (AnGS) undergoes calcification during wastewater treatment and affects the treatment efficiency.

Molecular Plant Pathology, Volume 24, Issue 11, Page 1400-1413, November 2023., 2023 The quorum sensing‐regulated synthesis of oxalic acid by ObcAB is needed to prevent alkaline degradation of C8‐HSL quorum sensing signalling molecules and avoid alkaline toxicity. The DedA family protein DbcA is required for oxalic acid secretion. Abstract Bacterial panicle blight is caused by Burkholderia glumae and results in damage to rice crops ...

Inhibiting N-acyl-homoserine lactone synthesis and quenching Pseudomonas quinolone quorum sensing to attenuate virulence [PDF]
, 2015 YesBacteria sense their own population size, tune the expression of responding genes, and behave accordingly to environmental stimuli by secreting signaling molecules. This phenomenon is termed as quorum sensing (QS).

Gac two-component system in Pseudomonas syringae pv. tabaci is required for virulence but not for hypersensitive reaction [PDF]
, 2008 Pseudomonas syringae pv. tabaci 6605 causes wildfire disease on host tobacco plants. To investigate the regulatory mechanism of the expression of virulence, Gac two-Component system-defective mutants, Delta gacA and Delta gacS, and a double mutant, Delta

MicrobiologyOpen, Volume 10, Issue 1, February 2021., 2021 Carotenoid production confers tolerance to toxoflavin and UV radiation in Pantoea ananatis. We proposed a model of carotenoid production for the previously reported regulatory network HfqArcZ → RpoS Ͱ ClpXP and that identified here, in which Hfq‐controlled quorum signaling derepresses EanR to activate RpoS expression, thereby initiating carotenoid ...
