N -Acyl-l-Homoserine Lactone Autoinducers Control Production of an Extracellular Lipopeptide Biosurfactant Required for Swarming Motility of Serratia liquefaciens MG1

Abstract: A nonswarming Serratia liquefaciens mutant deficient in serrawettin W2 production was constructed by transposon mutagenesis. Sequence homology indicated that insertion had occurred in gene swrA, which encodes a putative peptide synthetase. Expression of swrA is controlled by quorum sensing.

“…As seen in Fig. 3, media supplemented with purified serrawettin W2, allows the swrI mutant to travel across the agar surface [72]. One has to realize that inactivation of swrI neither affects growth rate or swimming motility, nor the development of hyperflagellation and cell elongation [73,74].…”

“…Understanding this has already led to the use of competitive antagonists (such as furanones) that can interfere with the signals that trigger bio¢lm di¡erentiation and decrease P. aeruginosa bio¢lm formation, for example [464 8]. For some bacteria, for example Serratia liquefaciens (which has one £agellar type for both swimming and swarming), QS has been shown to also in£uence the production of surfactant required for swarming motility on surfaces [49].…”

“…data). Quorum sensing controls attachment, swarming, exoenzyme secretion and biofilm formation in S. marcescens (Eberl et al ., 1996;Lindum et al ., 1998;Riedel et al ., 2001;Labbate et al ., 2004). This demonstrates that QS is broadly involved in surface-associated phenotypes and the secretion of extracellular products in S. marcescens .…”
