Comparative genome analysis reveals broad phylogenetic and functional diversity within the order Nitrospirales.

ABSTRACT: Nitrification, a key process in the nitrogen cycle, involves the oxidation of ammonia to nitrite and nitrate by a diverse group of chemolithoautotrophic microorganisms. The order Nitrospirales (referred to in literature as the genus Nitrospira), which includes both nitrite-oxidizing and complete ammonia-oxidizing bacteria, plays a central role in this process. We sequenced the genomes of nine Nitrospirales members, incorporating genomes from previously unsequenced taxonomic Nitrospirales lineages. A comprehensive genomic analysis of these new Nitrospirales was conducted, which included an examination of their habitat distribution, phylogenetic diversity, and functional capabilities. This was complemented by the construction of and comparison to a database of 446 non-redundant, high-quality
