Therefore, interfering with quorum sensing is currently being explored as a novel biocontrol strategy to fight bacterial infections. In this study, the effects of 19 micro-algal strains on acyl-homoserine lactone-regulated phenotypes of three reporter strains were investigated. Two freshwater micro-algae inhibited violacein production of quorum sensing reporter strain <i>Chromobacterium violaceum</i> CV026. Further tests using <i>Escherichia coli</i> JB523 showed that micro-algal extracts inhibited or stimulated quorum sensing, depending on the algal strain. One freshwater and five marine algae showed quorum sensing inhibitory activity, whereas two algae stimulated quorum sensing-regulated gene expression. Micro-algal strains that showed inhibitory activity in the previous assays also inhibited acyl-homoserine lactone-regulated bioluminescence in the aquaculture pathogen <i>Vibrio harveyi</i>. The growth of all reporter strains was found to be unaffected by the micro-algal samples. The most promising micro-algal strain was found to be <i>Chlorella saccharophila</i> CCAP211/48, as its extracts inhibited quorum sensing-regulated gene expression in all three reporter strains.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Effects of micro-algae commonly used in aquaculture on acyl-homoserine lactone quorum sensing","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Quorum sensing; Micro-algae; Quorum sensing interference; Luminescentvibrios","OtherDescriptors":null,"Notes":null,"AnaPub":2011,"MonPub":null,"DateUpdate":"2018-07-23","DateCreate":"2016-05-29","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000291908000009","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.aquaculture.2011.04.038"},"refs":null,"anarec":{"AnaID":257624,"PubliDate":2011,"Pagination":"53-57","XtraPublOfAnaID":null,"ISBN":null,"Volume":"317","Issue":"1-4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42190,"SerRR":"Aquaculture.
