‘Aigarchaeota’ is a candidate phylum of Archaea known only by 16S rRNA gene fragments from cultivation-independent microbial surveys and a single composite genome from Candidatus ‘Caldiarchaeum subterraneum’, an inhabitant of a subterranean gold mine in Japan. Gene sequences associated with ‘Aigarchaeota’ have been found in a variety of geothermal habits, however a comprehensive analysis of the phylogeny and distribution of ‘Aigarchaeota’ has not yet been done. Public databases were mined for 16S rRNA gene sequences related to known ‘Aigarchaeota’ and a combination of approaches were used to rigorously define the phylogenetic boundaries of the phylum, investigate its distribution, and …
