c.arac.erisation of the Bac.eria and Arc.aea c.m.unity Assoc.ated with Wild Oysters, At Three Possible Restoration Sites in the North Sea

Open Journal of m.rine Sc.enc. 2024年第2期14卷 19-40页

作者： Natac.a m. S. Juste-Poinapen Yang Lu Blanc. Bolaños De Hoyos George c. Birc. c.m.lle Saurel Oyster Heaven Rotterdam Netherlands Nuc.eus Rotterdam Netherlands m.c.obial Ec.logy and Wastewater m.c.obiology Queensland University of Technology Brisbane Australia National Institute of Aquatic.Resourc.s Technical University of Denmark Lyngby Denmark

With 85% of the global oyster reefs destroyed, there is an urgent need for large sc.le restoration to benefit from.the ec.system.servic.s provided by biogenic.oyster reefs and their assoc.ated biodiversity, inc.uding m.c.oorganism. that drive m.rine biogeoc.em.c.l c.c.es. This experim.nt established a baseline for the m.nitoring of the bac.erial and arc.aeal c.m.unity assoc.ated with wild oysters, using sam.les from.their im.ediate environm.nt of the Voordelta, with c.habiting c.assostrea gigas and Ostrea edulis, Duikplaats with only c. gigas attac.ed to roc.s, and the Dansk Skaldyrc.ntre, with no onsite oysters. The m.c.obial profiling was c.rried out through DNA analysis of sam.les c.llec.ed from.the surfac.s of oyster shells and their substrate, the sedim.nt and seawater. Following 16S rRNA am.lic.n sequenc.ng and bioinform.tic., alpha indic.s im.lied high spec.es abundanc. and diversity in sedim.nt but low abundanc. in seawater. As expec.ed, Proteobac.eria, Bac.eroidetes, Firm.c.tes and Thaum.rc.aeota dom.nated the top 20 OTUs. In the Voordelta, OTUs related to c.lwellia, Shewanella and Psyc.robium.differentiated the oysters c.llec.ed from.a reef with those attac.ed to roc.s. Duikplaats were distinc. for sulfur-oxidizers Sulfurim.nas and sulfate-reduc.rs from.the Sva 0081 sedim.nt group. Arc.aea were found m.inly in sedim.nts and the oyster assoc.ated m.c.obiom., with greater abundanc. at the reef site, c.nsisting m.stly of Thaum.rc.aeota from.the fam.ly Nitrosopum.lac.ae. The oyster free site displayed arc.aea in sedim.nts only, and algal bloom.indic.tor m.c.oorganism. from.the Rhodobac.erac.ae, Flavobac.eriac.ae fam.ly and genus [Polaribac.er] huanghezhanensis, in addition to the asc.dian sym.iotic.partner, Synec.oc.c.us. This study suggests site spec.fic.m.c.obiom. shifts, influenc.d by the presenc. of oysters and the type of substrate.
