Our recent study has demonstrated that epibiotic bacteria from the surface of the soft coral <i>Dendronephthya</i> sp. (Coelenterata: Octocoralia, Alcyonacea) inhibit the growth of bacteria commonly found in marine natural biofilms. In the present study, the effect of 11 epibiotic bacteria isolated from the surface of <i>Dendronephthya</i> sp. on larval settlement of the tubeworms <i>Hydroides elegans</i> was examined using laboratory bioassay. Among 11 bacterial isolates, 2 strains (18%) inhibited the larval settlement of <i>H. elegans</i> (Haswell), 4 strains (36%) were \"inductive\" to larvae and the remaining 5 strains (46%) were \"non-inductive\". There was no correlation between the antifouling activities of bacterial isolates and their phylogenetic origin, i.e. closely related bacterial strains showed different effects on larval settlement of <i>H. elegans</i>. When all \"inductive\", \"non-inductive\" and \"inhibitive\" bacterial isolates were mixed in a 1:1:1 ratio, the effect of the resultant multispecies film on larval settlement became \"inhibitive\". Waterborne compounds of <i>Vibrio</i> sp. and an unidentified alpha-<i>Proteobacterium</i>, which suppressed the settlement of <i>H. elegans</i> and <i>Bugula neritina</i> (L.) larvae, were further investigated using size fractionation and bioassay-guided enzymatic analysis. It was found that antilarval settlement compounds from these bacteria were heat-stable polysaccharides with a molecular weight >100 kDa. The results indicate that the bacteria associated with the soft coral <i>Dendronephthya</i> sp. may contribute to the antifouling mechanisms of the soft-bodied organisms by producing compounds that are against bacterial growth and settlement of macrofoulers on the surface of their host.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The role of epibotic bacteria from the surface of the soft coral <i>Dendronephthya</i> sp. in the inhibition of larval settlement","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":"antifouling; Bugula neritina; carbohydrates; Dendronephthya sp.;epibiotic bacteria; larval settlement; Hydroides elegans; soft coral","OtherDescriptors":"Dendronephthya sp.","Notes":null,"AnaPub":2004,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2004-02-02","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000188780500003","VABBcode":null,"OpenAcc":1,"DOI":"10.1016/j.jembe.2003.08.011"},"refs":null,"anarec":{"AnaID":57000,"PubliDate":2004,"Pagination":"35-50","XtraPublOfAnaID":null,"ISBN":null,"Volume":"299","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43229,"SerRR":"Journal of Experimental Marine Biology and Ecology.
