This study investigates the phytoplankton response to periodic ammonium pulses (every 5h20) in a nitrogen-limited culture of <i>Isochrysis galbana</i>. Results show that cells use additional ammonium. The cell response is not instantaneous and an adaptation period is observed in experiments. This period is characterized by (i) a decrease in latency stage during 10 mn after one pulse, (ii) an alternance of uptake/excretion processes decreasing throughout the experiment, (iii) an increasingly high and rapid surge-uptake phenomenon until pulse 6. We raise the question whether the Michaelis-Menten equation classically used to describe uptake processes is adequate in such an intermittent background.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Periodic ammonium pulses: are they important for the uptake kinetics of <i>Isochrysis galbana</i>?","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2001,"MonPub":null,"DateUpdate":"2002-10-17","DateCreate":"2002-10-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000173248900022","VABBcode":null,"OpenAcc":0,"DOI":"10.1023/A:1012524118495"},"refs":null,"anarec":{"AnaID":28564,"PubliDate":2001,"Pagination":"223-231","XtraPublOfAnaID":null,"ISBN":null,"Volume":"459","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42943,"SerRR":"Hydrobiologia.
