Abstract
Riftia pachyptila is a deep sea tube worm that is mainly found along the East Pacific Rise and the Galapagos Rift in the Eastern Pacific. Here it inhabits deep sea hydrothermal vents, sea floor geysers harvesting high temperatures, low pH, high pressure and strong chemical fumes. Despite these conditions R. pachyptila thrives, with growth rates exceeding those of other tubeworm species. Lacking a mouth and a gut, R. pachyptila is unable to feed, and depends on its endosymbiotic sulfur-oxidizing bacterium Candidatus Endoriftia Persephone for organic carbon supply. The discovery of this symbiosis in 1981 opened doors for researchers and greatly contributed to understanding the endosymbiosis between chemosynthetic bacteria and vent dwelling macro-organisms. Although attempts in culturing Candidatus E. Persephone outside of its host have not yet succeeded, a large part of its genome and protein map has been analyzed and provides a better insight in the lifestyle, metabolic pathways and diversity of this endosymbiont.
