Lineage: Trichormus azollae; Trichormus; Nostocaceae; Nostocales; Cyanobacteria; Bacteria
General Information: Isolation: water fern Azolla; Temp: Mesophile; Habitat: Host. Nostoc azollae, formerly Anabaena azollae, is a cyanobacterial symbiont of the water fern Azolla, commonly known as 'duckweed'. Nostoc azollae is a nitrogen-fixer and provides nitrogen to the host plant.
Subject: NC_009662:222964 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.
