title: Ignicoccus hospitalis sp. nov., the host of 'Nanoarchaeum equitans'.
abstract: A novel chemolithoautotrophic and hyperthermophilic member of the genus Ignicoccus was isolated from a submarine hydrothermal system at the Kolbeinsey Ridge, to the north of Iceland. The new isolate showed high similarity to the two species described to date, Ignicoccus islandicus and Ignicoccus pacificus, in its physiological properties as well as in its unique cell architecture. However, phylogenetic analysis and investigations on the protein composition of the outer membrane demonstrated that the new isolate was clearly distinct from I. islandicus and I. pacificus. Furthermore, it is the only organism known so far which is able to serve as a host for 'Nanoarchaeum equitans', the only cultivated member of the 'Nanoarchaeota'. Therefore, the new isolate represents a novel species of the genus Ignicoccus, which we name Ignicoccus hospitalis sp. nov. (type strain KIN4/I(T)=DSM 18386(T)=JCM 14125(T)).
