Here, we show that the K316 N/D500G mutant of CotA laccase from <i>Bacillus licheniformis</i> operates in basic media and seawater, electrocatalyzing O<sub>2</sub> reduction from 0.59 V, pH 8. CotA mutant's T1Cu center exhibits a formal potential of 0.56 V, consistent with an onset of bioelectrocatalytic reduction of O<sub>2</sub>. A photoelectrochemical cell recycling H<sub>2</sub>O/O<sub>2</sub> by a semiconductor photoanode and CotA mutant biocathode produced 41 and 11 μW cm<sup>2</sup>, in buffer and seawater, respectively, at pH 8, (electricity production being limited solely by the photoanode performance, reaching 240 and 220 μW cm<sup>−2</sup> in a Zn‐biobattery design), suggesting a prospective enzyme application for clean and sustainable production of electricity from seawater and oxygen.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"<i>Bacillus licheniformis</i> CotA laccase mutant: electrocatalytic reduction of O<sub>2</sub> from 0.6 V (SHE) at pH 8 and in seawater","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:01.897972","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"bacterial CotA laccase; bioelectrocatalysis; oxygen reduction; seawater;photo-biovoltaics","OtherDescriptors":null,"Notes":null,"AnaPub":2019,"MonPub":null,"DateUpdate":"2020-04-16","DateCreate":"2020-04-07","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000466798700012","VABBcode":null,"OpenAcc":0,"DOI":"10.1002/celc.201900363"},"refs":null,"anarec":{"AnaID":323220,"PubliDate":2019,"Pagination":"2043-2049","XtraPublOfAnaID":null,"ISBN":null,"Volume":"6","Issue":"7","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":258534,"SerRR":"ChemElectroChem.
