Involvement of Acylated Homoserine Lactones (AHLs) of Aeromonas sobria in Spoilage of Refrigerated Turbot (Scophthalmus maximus L.)
One quorum sensing strain was isolated from spoiled turbot. The species was determined by 16S rRNA gene analysis and classical tests, named Aeromonas sobria AS7. Quorum-sensing (QS) signals (N-acyl homoserine lactones (AHLs)) were detected by report strains and their structures were further determined by GC-MS. The activity changes of AHLs on strain growth stage as well as the influence of diff...
متن کاملAcylated homoserine lactones in the environment: chameleons of bioactivity.
Over the last 15 years, it has become increasingly apparent that a single class of compounds, the acylated homoserine lactones (AHLs), elicit effects on many levels of biological and ecological organization. Despite the fact that the distribution of AHL production in the prokaryotic phylogenetic tree is restricted to a small set of genera, representatives of these genera are abundant in the env...
متن کاملQuantification of Proteus mirabilis virulence factors and modulation by acylated homoserine lactones.
BACKGROUND AND PURPOSE Measurement of the main Proteus mirabilis virulence factors would increase our understanding of how the organism infects and colonizes the urinary tract. The purpose of this study was to quantify the virulence factors of twelve P. mirabilis laboratory strains and to determine whether expression of virulence factors of P. mirabilis depends on the presence of homoserine-lac...
متن کاملFast start-up anammox process using Acyl-homoserine lactones (AHLs) containing supernatant.
N-dodecanoyl homoserine lactone (C12-HSL) was detected in the supernatant of an anammox granular sludge reactor (AGSR). C12-HSL could enhance the specific anammox activity of anammox biomass. Adding C12-HSL-containing AGSR supernatant into the continuously stirred tank reactors reduced the start-up time of the anammox process from 80 to 66days. Moreover, the nitrogen loading rate was also enhan...
متن کاملPossible quorum sensing in marine snow bacteria: production of acylated homoserine lactones by Roseobacter strains isolated from marine snow.
We report here, for the first time, that bacteria associated with marine snow produce communication signals involved in quorum sensing in gram-negative bacteria. Four of 43 marine microorganisms isolated from marine snow were found to produce acylated homoserine lactones (AHLs) in well diffusion and thin-layer chromatographic assays based on the Agrobacterium tumefaciens reporter system. Three ...
