Metagenome of a nitrite-oxidizing enrichment from Austrian saline-alkaline lake containing Nitrospira alkalitolerans

Via the enrichment and genomic analyis of a new, haloalkalitolerant Lineage IV Nitrospira species, which we refer to as "Candidatus Nitrospira alkalitolerans”, we revealed several features that show the adaptation of this organism to its extreme environment and may help in overcoming low proton motive force, aid in pH and ion homeostasis and counter-regulate osmotic pressure.
