Survival was adversely affected at O<sub>2</sub> tensions exceeding 1-2% of atmospheric (air) saturation (atm. sat.): <i>Parablepharisma collare</i> survived for about 1 h at 100% atm. sat., while the other two species survived the treatment for up to 2 d. Survival in the presence of O<sub>2</sub> depended on the composition of the medium; cells survived longer in clean seawater than in culture medium which, when exposed to O<sub>2</sub>, became toxic. <i>Metopus contortus</i> and <i>Plagiopyla frontata</i> respired O<sub>2</sub> at rates similar to those of aerobic species; this O<sub>2</sub> uptake is not coupled to energy conservation since the ciliates do not contain cytochromes, and low O<sub>2</sub> tensions do not stimulate growth. O<sub>2</sub>  consumption is probably a detoxification mechanism which can maintain an intracellular anaerobic environment at a low ambient O<sub>2</sub> tension. <i>Metopus contortus</i> and <i>Plagiopyla frontata</i> showed chemosensory behaviour in response to O<sub>2</sub>; this allowed them to find and remain within anaerobic microhabitats.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Oxygen toxicity, respiration and behavioural responses to oxygen in free-living anaerobic ciliates","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-19 01:31:27.200906","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1990,"MonPub":null,"DateUpdate":"2017-01-31","DateCreate":"2009-06-11","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1990EF31800005","VABBcode":null,"OpenAcc":1,"DOI":"10.1099/00221287-136-10-1953"},"refs":null,"anarec":{"AnaID":137407,"PubliDate":1990,"Pagination":"1953-1959","XtraPublOfAnaID":null,"ISBN":null,"Volume":"136","Issue":"10","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":126653,"SerRR":"Journal of General Microbiology.
