nitrospirota 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 discovered in 1995. nitrospirota scientific classification domain: bacteria phylum: nitrospirotagarrity & holt 2021 classes & orders "leptospirillia" "leptospirillales" nitrospiria "nitrospirales" "troglogloeales" "thermodesulfovibrionia" "thermodesulfovibrionales" synonyms "nitrospirae" garrity and holt 2001 "nitrospiraeota" oren et al. 2015 "nitrospirota" whitman et al. 2018 nitrospirota contains nitrifying taxa which oxidize nitrite to nitrate (nitrite-oxidizing bacteria, nob) and commamox bacteria nitrospira inopinata discovered in 2015 and cultivated in 2017. phylogeny 16s rrna based ltp_12_2021 gtdb 07-rs207 by genome taxonomy database nitrospiraceae leptospirillum l. ferriphilum l. ferrooxidans thermodesulfovibrio t. hydrogeniphilus t. aggregans t. thiophilus t. islandicus t. yellowstonii "leptospirillia" "leptospirillales" "leptospirillaceae" "leptospirillum" l. ferrooxidans "l. rubarum" l. ferriphilum "thermodesulfovibrionia" "thermodesulfovibrionales" "magnetobacteriaceae" "ca. magnetobacterium casense" uba6898 "ca. sulfobium mesophilum" dissulfurispiraceae dissulfurispira thermophila thermodesulfovibrionaceae thermodesulfovibrio t. aggregans t. thiophilus t. yellowstonii "nitrospiria" "troglogloeales" "manganitrophaceae" "ca. manganitrophus noduliformans" "nitrospirales" "nitrospiraceae" nitrospira "n. defluvii" "n. japonica" "n. lenta" n. moscoviensis "ca. n. inopinata" "ca. n. kreftii" "ca. n. nitrosa" "ca. n. nitrificans" taxonomy the currently accepted taxonomy is based on the list of prokaryotic names with standing in nomenclature (lspn) and the national center for biotechnology information (ncbi). phylum "nitrospirota" garrity & holt 2021 class "leptospirillia" order "leptospirillales" family "leptospirillaceae" cavalier-smith 2020 genus leptospirillum markosyan 1972 ex hippe 2000 species "l. ferrodiazotrophum" tyson et al. 2005 species l. ferriphilum coram & rawlings 2002 species l. ferrooxidans markosyan 1972 ex hippe 2000 species "l. rubarum" aliaga goltsman et al. 2009 species l. thermoferrooxidans hippe 2000 class nitrospiria oren et al. 2015 order "troglogloeales" yu et al. 2022 genus "candidatus troglogloea" corrig. kostanjsek et al. 2013 species "ca. t. absolonii" corrig. kostanjsek et al. 2013 family "manganitrophaceae" yu et al. 2022 genus "candidatus manganitrophus" yu & leadbetter 2020 species "ca. m. morganii" yu et al. 2022 species "ca. m. noduliformans" yu & leadbetter 2020 order "nitrospirales" garrity & holt 2001 family "nitrospiraceae" garrity & holt 2001 genus "ca. magnetominusculus" lin et al. 2017 species "ca. m. xianensis" lin et al. 2017 genus nitrospira watson et al. 1986 species "ca. n. alkalitolerans" daebeler et al. 2020 species "ca. n. bockiana" lebedeva et al. 2008 species n. calida lebedeva et al. 2011 species n. defluvii nowka et al. 2015 species "ca. n. inopinata" daims et al. 2015 species n. japonica ushiki et al. 2013 species "ca. n. kreftii" sakoula et al. 2021 species n. lenta nowka et al. 2015 species n. marina watson et al. 1986 (type sp.) species n. moscoviensis ehrich et al. 1995 species "ca. n. nitrificans" van kessel et al. 2015 species "ca. n. nitrosa" van kessel et al. 2015 species "ca. n. salsa" haaijer et al. 2013 class thermodesulfovibrionia umezawa et al. 2021 order "thermodesulfovibrionales" umezawa et al. 2021 family dissulfurispiraceae umezawa et al. 2021 genus dissulfurispira umezawa et al. 2021 species d. thermophila umezawa et al. 2021 family thermodesulfovibrionaceae umezawa et al. 2021 genus "candidatus magnetobacterium" spring et al. 1993 species "ca. m. bavaricum" spring et al. 1993 species "ca. m. casense" corrig. lin et al. 2014 genus "candidatus magnetovum" corrig. lefevre et al. 2011 species "ca. m. chiemensis" kolinko 2014 species "ca. m. mohavensis" lefevre et al. 2011 genus "candidatus sulfobium" zecchin et al. 2018 species "ca. s. mesophilum" zecchin et al. 2018 genus thermodesulfovibrio henry et al. 1994 emend. sekiguchi et al. 2008 species t. aggregans sekiguchi et al. 2008 species t. hydrogeniphilus haouari et al. 2009 species t. islandicus sonne-hansen and ahring 2000 species t. thiophilus sekiguchi et al. 2008 species t. yellowstonii henry et al. 1994 (type sp.)
