The shell of mussels is intensively colonized by microbial organisms that can produce significant quantities of nitrous oxide (N<sub>2</sub>O), a potent greenhouse gas. To characterize the impacts of climate change on the composition, structure and functioning of microbial biofilms on the shell surface of <i>M. edulis</i>, we experimentally exposed them to orthogonal combinations of increased seawater temperature (20 vs. 23&nbsp;°C) and decreased pH (8.0 vs. 7.7) for six weeks. We used amplicon sequencing of the 16S rRNA gene to characterize the alpha and beta diversity of microbial communities on the mussel shell. The functioning of microbial biofilms was assessed by measuring aerobic respiration and nitrogen emission rates. We did not report any significant impacts of climate change treatments on the diversity of mussel microbiomes nor on the structure of these communities. Lowered pH and increased temperature had antagonistic effects on the functioning of microbial communities with decreased aerobic respiration and N<sub>2</sub>O emission rates of microbial biofilms in acidified seawater compared to increased rates in warmer conditions. An overriding impact of acidification over warming was finally observed on N<sub>2</sub>O emissions when the two factors were combined. Although acidification and warming in combination significantly reduced N<sub>2</sub>O biofilm emissions, the promotion of aquaculture activities in coastal waters where shellfish do not normally occur at high biomass and density could nonetheless result in unwanted emissions of this greenhouse gas in a near future.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Structurally stable but functionally disrupted marine microbial communities under a future climate change scenario: Potential importance for nitrous oxide emissions","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-21 01:33:25.131581","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Ocean acidification; Ocean warming; Microbial biofilms; Bivalves; Nitrogen fluxes; Greenhouse gas emission","OtherDescriptors":null,"Notes":null,"AnaPub":2024,"MonPub":null,"DateUpdate":"2025-09-18","DateCreate":"2023-10-23","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:001102898000001","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.scitotenv.2023.167928"},"refs":null,"anarec":{"AnaID":368260,"PubliDate":2024,"Pagination":"167928","XtraPublOfAnaID":null,"ISBN":null,"Volume":"907","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43780,"SerRR":"Science of the Total Environment.
