Query: NC_012796:985000 Desulfovibrio magneticus RS-1, complete genome
Lineage: Desulfovibrio magneticus; Desulfovibrio; Desulfovibrionaceae; Desulfovibrionales; Proteobacteria; Bacteria
General Information: Isolated from freshwater sulfide-rich mud of a waterway near Kameno river, Wakayama, in Japan. This organism is a sulfate-reducing delta proteobacterium which synthesizes intracellular magnetite particles. Desulfovibrio magneticus produces irregular, membrane-bound magnetite particles, unlike other magnetite-producing bacteria which contain crystalline magnetite in the cytoplasm. Desulfovibrio magneticus does not migrate along a magnetic field but swims randomly.
Subject: NC_004757:1021355 Nitrosomonas europaea ATCC 19718, complete genome
Lineage: Nitrosomonas europaea; Nitrosomonas; Nitrosomonadaceae; Nitrosomonadales; Proteobacteria; Bacteria
General Information: Ammonia-oxidizing bacterium. This organism is an obligate chemo-lithoautotroph as it only uses ammonia and carbon dioxide and mineral salts for growth, and is an important part of the global biogeochemical nitrogen cycle. It can derive all energy requirements from the oxidation of ammonia to nitrate, driving global nitrogen from the reduced insoluble form to the oxidized and potentially gaseous form (including NO and NO2 which are greenhouse gases). The energy derived from ammonia oxidation is in turn used to drive carbon fixation. This bacterium also provides plants with a readily available form of nitrogen, is important in wastewater treatment, and may be involved in bioremediation of sites contaminated with toxic compounds.
