Query: NC_009954:117895 Caldivirga maquilingensis IC-167, complete genome
Lineage: Caldivirga maquilingensis; Caldivirga; Thermoproteaceae; Thermoproteales; Crenarchaeota; Archaea
General Information: Hyperthermophilic crenarchaeota. Caldivirga maquilingensis was isolated from an acidic hot spring in the Philippines. It is a microaerophilic heterotroph and is able to use sulfur, thiosulfate, and sulfate as electron acceptors.
Subject: NC_009662:645871 Nitratiruptor sp. SB155-2, complete genome
Lineage: Nitratiruptor; Nitratiruptor; Nautiliaceae; Nautiliales; Proteobacteria; Bacteria
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.
