''Nitrospira inopinata'' is a bacterium from the phylum

Nitrospirota Nitrospirota is a phylum of bacteria. It includes multiple genera, such as '' Nitrospira'', the largest. The first member of this phylum, '' Nitrospira marina'', was discovered in 1985. The second member, '' Nitrospira moscoviensis'', was discove ...

. This phylum contains nitrite-oxidizing bacteria playing role in

nitrification ''Nitrification'' is the biological oxidation of ammonia to nitrite followed by the oxidation of the nitrite to nitrate occurring through separate organisms or direct ammonia oxidation to nitrate in comammox bacteria. The transformation of am ...

. However ''N. inopinata'' was shown to perform complete ammonia oxidation to nitrate thus being the first

comammox Comammox (COMplete AMMonia OXidation) is the name attributed to an organism that can convert ammonia into nitrite and then into nitrate through the process of nitrification. Nitrification has traditionally thought to be a two-step process, where amm ...

bacterium to be discovered. ''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,
