The cultures were exposed to natural solar radiation and grown over 72 h and 6 days under three experimental irradiance treatments: (1) photosynthetic available radiation (PAR) + UVR (280-700 nm), (2) PAR + UVA (315-700 nm), and (3) PAR (400-700 nm). Two MAAs were identified and quantified in the cells: porphyra-334 and shinorine. The cultures showed an initial period of growth inhibition and the rate of synthesis of MAAs (µ) was very high in all treatments in the short-term experiment and during the first 2 days of the long-term experiment. No differences between treatments were observed in the accumulation of these compounds. After 2 days of exposure, however, the MAA content per cell was several times higher than that initially found in all treatments, and the cells exposed to the PAR + UVR treatment displayed the maximum concentration.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Effects of solar radiation on growth and mycosporine-like amino acids content in <i>Thalassiosira</i> sp, an Antarctic diatom","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":2002,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2007-12-11","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000173278100003","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s003000100306"},"refs":null,"anarec":{"AnaID":117870,"PubliDate":2002,"Pagination":"12-20","XtraPublOfAnaID":null,"ISBN":null,"Volume":"25","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43637,"SerRR":"Polar Biology.
