摘要：
A thermoacidophilic, anaerobic, and iron- and sulfur-reducing archaeon, strain NAS-02(T), was isolated from a terrestrial hot spring in Japan, as previously reported. This organism is the first non-ammonia-oxidizing isolate in the phylum Thaumarchaeota. Here, we propose Conexivisphaera calida gen. nov., sp. nov. to accommodate this strain. The type strain of the type species is NAS-02(T) (=JCM 31663(T)=DSM 105898(T)). The values of 16S rRNA gene similarity and average amino acid identity between NAS-02(T) and its closest relatives are <86 and <42%, respectively. Based on the phylogeny and physiology, we propose the family Conexivisphaeraceae fam. nov., the order Conexivisphaerales ord. nov. and the class Conexivisphaeria class. nov. to accommodate the novel genus.
