Query: NC_012115:691154 Nautilia profundicola AmH, complete genome Lineage: Nautilia profundicola; Nautilia; Nautiliaceae; Nautiliales; Proteobacteria; Bacteria General Information: Thermophilic sulfur-reducing bacterium. Nautilia can be isolated from the epidermis of the hydrothermal vent worm, Alvinella pompejana and from hydrothermal vent chimneys. These organisms grow chemoautotrophically on hydrogen, sulfur, and CO2. Nautilia profundicola is a thermophilic, hydrogen-oxidizing, sulfur-reducing chemoautotroph that uses the reductive TCA cycle for carbon fixation. It is a member of the deepest branch of the Epsilonproteobacteria and is a model organism of the anaerobic autotrophic Epsilonproteobacteria at hydrothermal vents.

General Information: This strain was isolated from a deep-sea hydrothermal vent in the Iheya North field in the Mid-Okinawa Trough, Japan as part of a larger diversity study. This rod-shaped bacterium grows chemolithoautotrophically and can utilize a wide spectrum of electron donors and acceptors (i.e. hydrogen, sulfur compounds, nitrate and oxygen). It can occupy different ecological niches, and its metabolic versatility probably enables it to adapt to the geochemical variability in deep-sea hydrothermal environments.
