The morphology and pigment composition of these two strains, one identified as <i>Phaeocystis globosa</i> and the other as <i>Imantonia rotunda</i>, were carefully examined. The comparative analysis of their pigment signature revealed the presence of two fucoxanthin derivatives, 19'-butanoyloxyfucoxanthin and 19'-hexanoyloxyfucoxanthin (but-fuco and hex-fuco) in <i>I. rotunda</i>, which were undetectable in <i>P. globosa</i>. A further comparison of pigments and phytoplankton from field samples showed no significant correlation between hex-fuco concentration and <i>P. globosa</i> biomass in the water column. Low concentrations of this pigment were, however, detectable before and at the end of the Phaeocystis bloom. The presence of <i>I. rotunda</i> in the area, overlooked by light microscopy, but isolated in pure culture from field samples, might explain the presence of this pigment. We conclude that hex-fuco is not the appropriate pigment to estimate <i>Phaeocystis</i> abundance and trace its trophic fate in Belgian coastal waters. These results also indicate that pigment analysis should be coupled with a precise identification of phytoplankton taxa present in field samples.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"19'-hexanoyloxyfucoxanthin may not be the appropriate pigment to trace occurrence and fate of<i> Phaeocystis</i>: the case of <i>P. globosa</i> in Belgian coastal waters","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:01.897972","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Phaeocystis globosa; Imantonia rotunda; SEM; HPLC pigments","OtherDescriptors":"Phaeocystis globosa; Imantonia rotunda; SEM; HPLC pigments","Notes":null,"AnaPub":2004,"MonPub":null,"DateUpdate":"2012-04-04","DateCreate":"2004-09-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000224139600002","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.seares.2004.02.003"},"refs":null,"anarec":{"AnaID":66530,"PubliDate":2004,"Pagination":"165-177","XtraPublOfAnaID":null,"ISBN":null,"Volume":"52","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43261,"SerRR":"Journal of Sea Research.
