Laboratory experiments were performed with bacteria-sized fluorescent latex microspheres of 0.5, 1.1, and 4.5 µm diameter, as well as with live cells of the bacteria <i>Vibrio</i> sp. and <i>Serratia plymuthica</i>. Results indicate that <i>Noctiluca</i> can remove microspheres and bacteria at a rate of 10 4 to 10 6 individual -1 hour -1 , under the given laboratory conditions. Data on abundance of <i>Noctiluca</i>, different groups of bacteria, yeasts, nanoflagellates, and microbial exoenzyme activity in the southern North Sea are compared. Although removal of bacteria by <i>Noctiluca</i> in the field is generally not reflected in the occurrence of these organisms, it is possible that <i>Noctiluca</i> ingests bacteria in the winter when other food sources are scarce. During its exponential growth, <i>Noctiluca</i> may remove bacteria from the water column together with other potential and actual food organisms trapped in its mucoid webs.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Does the red tide-forming dinoflagellate <i>Noctiluca scintillans</i> feed on bacteria ?","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":1996,"MonPub":null,"DateUpdate":"2003-02-12","DateCreate":"2003-01-30","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":31793,"PubliDate":1996,"Pagination":"45-55","XtraPublOfAnaID":null,"ISBN":null,"Volume":"81","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43909,"SerRR":"Sarsia.
