Depending on the vent water flow and the degree of mixing, this environment is extremely unstable and can change quickly. Johnson et al. (1988) showed that <i>R. pachyptila</i> and other vent species may experience high sulphide concentrations as well as extreme hypoxia over both short and long periods of time. The sessile tubeworm cannot escape from the frequently hypoxic conditions since it harbours chemoautotrophic, sulphide-oxidizing bacteria in its trophosome cells that require access to the sulphidic vent source as well as to an oxidant. While the symbiotic bacteria could, alternatively, use nitrate or oxygen to oxidize sulphide (Hentschel & Felbeck, 1993), the heterotrophic host <i>R. pachyptila</i> has no nitrate reductase and requires oxygen to maintain its normal aerobic metabolism. We investigated in our study the metabolic capabilities of <i>R. pachyptila</i> to tolerate periods of extreme hypoxia as they frequently occur in its habitat. To characterize the anaerobic metabolic changes of the tubeworm, specimens of <i>R. pachyptila</i> were exposed to experimental hypoxia for different periods of time.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Anaerobiosis in the hydrothermal vent tube-worm <i>Riftia pachyptila</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-21 01:31:38.450340","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1998,"MonPub":null,"DateUpdate":"2021-02-16","DateCreate":"2004-09-29","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000078751400013","VABBcode":null,"OpenAcc":1,"DOI":"10.21411/CBM.A.D23A1E9A"},"refs":null,"anarec":{"AnaID":66562,"PubliDate":1998,"Pagination":"271-273","XtraPublOfAnaID":null,"ISBN":null,"Volume":"39","Issue":"3-4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42348,"SerRR":"Cahiers de Biologie Marine.
