Query: NC_014248:685656 Nostoc azollae 0708 chromosome, complete genome
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_014355:1257105 Candidatus Nitrospira defluvii, complete genome
Lineage: Nitrospira defluvii; Nitrospira; Nitrospiraceae; Nitrospirales; Nitrospirae; Bacteria
General Information: This nitrite-oxidizing bacterium was found through enrichment from activated sludge from a municipal wastewater treatment plant. Phylogenetic analysis of 16S rRNA gene sequences revealed that the enriched bacteria represented a novel Nitrospira species closely related to uncultured Nitrospira-like bacteria previously found in wastewater treatment plants and nitrifying bioreactors.
