Journal ArticleDOI
Rhamnolipids: diversity of structures, microbial origins and roles
TL;DR: A wide diversity of rhamnolipid congeners and homologues that are produced at different concentrations by various Pseudomonas species and by bacteria belonging to other families, classes, or even phyla are found.
Journal ArticleDOI
Analysis of Pseudomonas aeruginosa 4-hydroxy-2-alkylquinolines (HAQs) reveals a role for 4-hydroxy-2-heptylquinoline in cell-to-cell communication.
Eric Déziel,François Lépine,Sylvain Milot,Jianxin He,Michael N. Mindrinos,Ronald G. Tompkins,Laurence G. Rahme +6 more
TL;DR: This work finds that anthranilic acid, the product of the PhnAB synthase, is the primary precursor of HAQs and that the HAQ congener 4-hydroxy-2-heptylquinoline (HHQ) is the direct precursor of the PQS signaling molecule.
Journal ArticleDOI
Genomic analysis reveals that Pseudomonas aeruginosa virulence is combinatorial

Rahme,Frederick M. Ausubel +20 more
TL;DR: It is proposed that virulence in this organism is both multifactorial and combinatorial, the result of a pool of pathogenicity-related genes that interact in various combinations in different genetic backgrounds.
Journal ArticleDOI
Initiation of Biofilm Formation by Pseudomonas aeruginosa 57RP Correlates with Emergence of Hyperpiliated and Highly Adherent Phenotypic Variants Deficient in Swimming, Swarming, and Twitching Motilities
TL;DR: This report describes the characterization of phenotypic variants forming small, rough colonies that spontaneously emerged when P. aeruginosa 57RP was cultivated as a biofilm or in static liquid cultures, and concludes that these S variants resulted from phase variation and were selectively enriched when.
Journal ArticleDOI
rhlA is required for the production of a novel biosurfactant promoting swarming motility in Pseudomonas aeruginosa: 3-(3-hydroxyalkanoyloxy)alkanoic acids (HAAs), the precursors of rhamnolipids.
TL;DR: Evidence is presented indicating that rhlA is required for production of HAAs and that these HAAs display potent surface-active properties, and it was shown that the use of ammonium instead of nitrate as source of nitrogen and an excess of available iron both decrease rhLA expression and swarming motility.
