Nitrospira Defluvii
''Nitrospira'' (from Latin: nitro, meaning "nitrate" and Greek: spira, meaning "spiral") translate into “a nitrate spiral” is a genus of bacteria within the monophyletic clade of the Nitrospirota phylum. The first member of this genus was described 1986 by Watson et al. isolated from the Gulf of Maine. The bacterium was named ''Nitrospira marina''. Populations were initially thought to be limited to marine ecosystems, but it was later discovered to be well-suited for numerous habitats, including activated sludge of wastewater treatment systems, natural biological marine settings (such as the Seine River in France and beaches in Cape Cod), water circulation biofilters in aquarium tanks, terrestrial systems, fresh and salt water ecosystems, and hot springs. Nitrospira is a ubiquitous bacterium that plays a role in the nitrogen cycle by performing nitrite oxidation in the second step of nitrification. ''Nitrospira'' live in a wide array of environments including but not limited ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desulfoarculaceae
Desulfobacterales are an order of sulfate-reducing bacteria within the phylum Thermodesulfobacteria. The order contains three families; ''Desulfobacteraceae, Desulfobulbaceae'', and ''Nitrospinaceae''. The bacterium in this order are strict anaerobic respirators, using sulfate or nitrate as the terminal electron acceptor instead of oxygen. Desulfobacterales can degrade ethanol, molecular hydrogen, organic acids, and small hydrocarbons. The bacterium of this order have a wide ecological range and play important environmental roles in symbiotic relationships and nutrient cycling. Habitat Desulfobacterales are found globally and often in extreme environments, such as deep-sea hydrothermal vents, hot springs, marine sediment, and solfataric fields, an area of volcanic venting that gives off sulfurous gases. Symbiotic Relationships Sulfate-reduction by ''Desulfobacteraceae'' and ''Desulfobulbaceae'' in coastal marine sediments plays an important role in molecular hydrogen cyclin ...
