Query: NC_012796:4075583 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_010364:3322 Halobacterium salinarum R1, complete genome
Lineage: Halobacterium salinarum; Halobacterium; Halobacteriaceae; Halobacteriales; Euryarchaeota; Archaea
General Information: Chemoheterotrophic obligate extreme halophilic archeon. Halobacterial species are obligately halophilic microorganisms that have adapted to optimal growth under conditions of extremely high salinity 10 times that of sea water. This bacterium (strain R1; DSM 671) is an obligately halophilic archeon and represents the type species for the genus Halobacterium. The first recorded isolation of this organism came from the spoilage of salted fish. It is also commonly found in neutral salt lakes, marine salterns, proteinaceous products heavily salted with crude solar salt and ancient evaporate deposits.
