The kinetics of acyl homoserine lactone (AHL) degradation was established and the poly-beta-hydroxybutyrate (PHB) content of the obtained ECs was determined. The ECs were characterised through denaturing gradient gel electrophoresis (DGGE) and the main bands were genetically identified by sequence analysis. In a <i>Vibrio</i> challenge test using <i>Artemia</i> as target organism, a distinct difference in survival of challenged <i>Artemia</i> between the treatments with and without the presence of ECs was observed (53% +/- 6; 69% +/- 5 and 58% +/- 8 versus 4% +/- 5; 4% +/- 5 and 25% +/- 21) in three independent experiments. There was a strong positive correlation between the relative percentage survival values of <i>Artemia</i> and the AHL degradation rate and the PHB content of the ECs. Challenge data with a quorum sensing mutant suggested that the quorum quenching ability of the ECs was less relevant in this <i>Artemia</i> model system, pointing to the importance of PHB. The potential of growing these beneficial ECs on glycerol released into the hatching medium of <i>Artemia</i> was an asset that still requires validation at hatchery level.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Novel approach of using homoserine lactone-degrading and poly-beta-hydroxybutyrate-accumulating bacteria to protect <i>Artemia</i> from the pathogenic effects of <i>Vibrio harveyi</i>","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; N-acyl homoserine lactone; Enrichment culture;","OtherDescriptors":null,"Notes":null,"AnaPub":2009,"MonPub":null,"DateUpdate":"2015-11-06","DateCreate":"2011-12-22","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000266518300003","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.aquaculture.2009.03.009"},"refs":null,"anarec":{"AnaID":210632,"PubliDate":2009,"Pagination":"23-30","XtraPublOfAnaID":null,"ISBN":null,"Volume":"291","Issue":"1-2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42190,"SerRR":"Aquaculture.
