Charcoal filtration did not entirely remove the toxicity. Algal extracts were more toxic than algal filtrates. Cell lysis induced by osmotic-shock treatment caused auto-inhibition in a dense culture of <i>Ditylum brightwellii</i>; cells of this species recovered from a low salinity treatment after addition of charcoal to a culture. In mixed cultures the growth of both species may be affected by mutual inhibition. Toxicity of media depends on the growth phase of the competitors. In dense cultures, comparable with algal blooms in eutrophic waters, exocrines may be more effective than in diluted cultures (<i>cf.</i> mesotrophic waters). Substances excreted in dense blooms of <i>S. costatum</i> may inhibit competing species.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Competitive interaction between <i>Ditylum brightwellii</i> and <i>Skeletonema costatum</i> by toxic metabolites","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":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1989,"MonPub":null,"DateUpdate":"2016-02-16","DateCreate":"2001-08-20","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":15991,"PubliDate":1989,"Pagination":"23-27","XtraPublOfAnaID":null,"ISBN":null,"Volume":"23","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44573,"SerRR":"Netherlands Journal of Sea Research.
