Nitrospira inopinata is a bacterium from the phylum Nitrospirota. This phylum contains nitrite-oxidizing bacteria playing role in nitrification. However N. inopinata was shown to perform complete ammonia oxidation to nitrate thus being the first comammox bacterium to be discovered.[1][2]

N. inopinata was cultivated in enrichment culture. Initial inoculum was obtained in 2011 from microbial biofilm growing on metal surface of the pipe covered by hot water (56 °C, pH 7.5), which was raised from 1 200m deep oil exploration well. The well was located in Aushiger, North Caucasus, Russia.[1] The growth in pure culture was achieved in 2017.[3]

Genome of N. inopinata was released in 2015 represented by 3.3 Mbp, with 3 116 genes and 59.2% GC content. NCBI accession number is LN885086.
