The phylum Nanoarchaeota: present knowledge and future perspectives of a unique form of life

Res Microbiol. 2003 Apr;154(3):165-71. doi: 10.1016/S0923-2508(03)00035-4.

Abstract

The "Nanoarchaeota" are a novel archaeal phylum, forming a unique, deep branch in the 16S rRNA based phylogenetic tree of life. "Nanoarchaeum equitans", the first cultivated representative, is a hyperthermophilic, anaerobic nano-sized coccus with a genome size of about 490 kb. Growth occurs only in coculture with a new chemolithoautotrophic Ignicoccus species.
