However, residual flocculants can interfere in further downstream processes or influence biomass quality. In this study, a new concept is demonstrated based on reversible magnesium hydroxide flocculation, using <i>Chlorella vulgaris</i> and <i>Phaeodactylum tricornutum</i> as, respectively, a freshwater and a marine model species. We show that flocculation was induced by precipitation of magnesium hydroxide at high pH (10 to 10.5). This resulted in a magnesium content of the microalgal biomass of 5 % for <i>Chlorella</i> and 18 % for <i>Phaeodactylum</i>. After pre-concentration of the microalgal biomass by gravity sedimentation, 95 % of the precipitated magnesium hydroxide could be removed from the biomass by mild acidification (pH 7 to 8). The pH fluctuations experienced by the microalgae during flocculation/de-flocculation had no influence on biomass composition (FAME, total N and P, carbohydrates, proteins, mineral content) and on the viability of microalgal cells. Magnesium can thus be used as pH-dependent reversible flocculant for harvesting microalgae in both marine and freshwater medium.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Reversible flocculation of microalgae using magnesium hydroxide","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":2015,"MonPub":null,"DateUpdate":"2019-06-26","DateCreate":"2015-06-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000354028200018","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s12155-014-9554-1"},"refs":null,"anarec":{"AnaID":247865,"PubliDate":2015,"Pagination":"716-725","XtraPublOfAnaID":null,"ISBN":null,"Volume":"8","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":210024,"SerRR":"Bioenergy Research.
