Growth, measured as fresh weight increment, increased with irradiance up to 130 µmol m<sup>-2</sup> s<sup>-1</sup> and no significant photoinhibition was observed up to 430 µmol m<sup>-2</sup> s<sup>-1</sup>. Maximum growth rate (10.0% day<sup>-1</sup>) was obtained at 130-240 µmol m<sup>-2</sup> s<sup>-1</sup> under continuous light and aeration. The effect of irradiance on agar yield and quality was assessed. Agar yield varied from 31 to 38.6% of the algal dry weight, and variation was not related to irradiance. However, the yield of agar molecules soluble at 95 °C increased with increasing irradiance. A similar trend was found for sulphate content in both series of extracts, at 95 and 121 °C. On the contrary, the molecular weight and the degree of methylation of agar molecules in the 95 °C extracts decreased with increasing light intensity. As a consequence of the variations in sulphate content, molecular weight and molecular weight distribution, the gel strength was considerably lower at high light intensity. Starch content varied from 0.9 to 7.7% of the algal dry weight, and apparently was not related with irradiance.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The effect of light on growth and agar content of <i>Gelidium pulchellum</i> (Gelidiaceae, Rhodophyta) in culture","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":1999,"MonPub":null,"DateUpdate":"2002-04-17","DateCreate":"2002-04-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000082676900041","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":24106,"PubliDate":1999,"Pagination":"329-338","XtraPublOfAnaID":null,"ISBN":null,"Volume":"399","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42943,"SerRR":"Hydrobiologia.
