Using universal primers targeting 16S rRNA gene via Hiseq sequencing, we explored archaeal and bacterial diversity, structure and relationships in the largest natural deep lake in Western Europe, i.e. Lake Geneva. Despite being less diverse than bacteria, archaea dominant OTUs assigned to the phylum Thaumarchaeota and Nanoarchaeota displayed significant links with a variety of nitrifying bacteria and other bacteria as suggested by co-occurrence networks and function profil predictions. We propose that archaeal OTUs were most likely involved in nitrogen and methanogen cycles and formed a nitrogen and methanogen consortium with other bacteria in deep layers of the lake. These probable syntrophic or mutualistic associations suggest that dominant archaeal OTUs share with some bacteria a similar niche for mutual benefits.</p>}, number={2}, journal={Advances in Oceanography and Limnology}, author={Ezzeline, Jade A. and Desdevises, Yves and Jacquet, Stéphan}, year={2020}, month={Dec.} }
