We investigated cationic cellulose nanocrystals (CNCs) as biobased flocculants for the marine microalgae <em>Nannochloropsis oculata</em>, and compared its performance to chitosan. Cationic CNCs induced flocculation at a low dose of 11 mg L<sup>-1</sup>, while chitosan required a dose of 35 mg L<sup>-1</sup>. Our cationic CNCs possess a permanent positive charge, allowing flocculation over a wide pH-range (4 to 10). The CNC maximum flocculation efficiency was 90 %, while chitosan achieved > 95 %, attributed to small flocs remaining in suspension for CNCs. However, centrifugation for 1 min at 180 g or gravity filtration using a 30 μm nylon filter after CNC flocculation resulted in the removal of these small, stable flocs (∼150 μm diam) and > 95% harvesting efficiency. Cationic CNCs can thus serve as a sustainable alternative natural flocculant for harvesting both freshwater and marine microalgae.</p>","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Harvesting of marine microalgae using cationic cellulose nanocrystals","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":"marine microalgae; cellulose nanocrystals; biobased flocculants","OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2021-06-02","DateCreate":"2020-05-29","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000537314900030","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.carbpol.2020.116165"},"refs":null,"anarec":{"AnaID":324647,"PubliDate":2020,"Pagination":"116165","XtraPublOfAnaID":null,"ISBN":null,"Volume":"240","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":265369,"SerRR":"Carbohydrate Polymers.
