NO is a poor nitrogen source for algae cultivation because of its low reactivity and solublilty in water and its toxicity for algae at high concentrations. Here, we present a novel strategy to valorize NO from flue gas as feedstock for algae production by combining a photocatalytic gas pretreatment unit with a microalgal photobioreactor. The photocatalytic air pretreatment transforms NO gas into NO<sub>2</sub> gas and thereby enhances the absorption of NO<sub><i>x</i></sub> in the cultivation broth. The absorbed NO<sub><i>x</i></sub> will form NO<sub>2</sub><sup>–</sup> and NO<sub>3</sub><sup>–</sup> that can be used as a nitrogen source by algae. The effect of photocatalytic air pretreatment on the growth and biomass productivity of the algae <i>Thalassiosira weissflogii</i> in a semicontinuous system aerated with a model flue gas (1% CO<sub>2</sub> and 50 ppm of NO) is investigated during a long-term experiment. The integrated system makes it possible to produce algae with NO from flue gas as the sole nitrogen source and reduces the NO<sub><i>x</i></sub> content in the exhaust gas by 84%.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Valorization of flue gas by combining photocatalytic gas pretreatment with microalgae production","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-18 01:31:58.644582","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2016,"MonPub":null,"DateUpdate":"2020-09-01","DateCreate":"2017-07-25","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000371371700048","VABBcode":null,"OpenAcc":0,"DOI":"10.1021/acs.est.5b04824"},"refs":null,"anarec":{"AnaID":287087,"PubliDate":2016,"Pagination":"2538-2545","XtraPublOfAnaID":null,"ISBN":null,"Volume":"50","Issue":"5","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42837,"SerRR":"Environmental Science and Technology.
