Vibrio variabilis T01: A tropical marine bacterium exhibiting unique N -acyl homoserine lactone production.

Vibriospp. have been widely studied for their unique properties such as pathogenicity and quorum sensing (QS) abilities. This article presents the identification ofVibrio variabilisstrain T01 isolated from Malaysian coastal waters. Strain T01 ofV. variabiliswas identified to produce QS molecules as tested using a biosensor. High-resolution tandem mass spectrometry was used to identifyN-acyl homoserine lactone (AHL) profiles of strain T01. Three AHLs,viz. N-hexanoyl-L-homoserine lactone (C6-HSL),N-(3-oxodecanoyl)-L-homoserine lactone (3-oxo-C10-HSL) andN-dodecanoyl-L-homoserine lactone (C12-HSL), were confirmed. To the authors' knowledge, this is the first documentation of AHL profiles fromV. variabilisstrain T01, which expands the number of QS members inVibriospp. [ABSTRACT FROM AUTHOR]
