Diatom
A diatom (New Latin, Neo-Latin ''diatoma''), "a cutting through, a severance", from el, διάτομος, diátomos, "cut in half, divided equally" from el, διατέμνω, diatémno, "to cut in twain". is any member of a large group comprising several Genus, genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world. Living diatoms make up a significant portion of the Earth's Biomass (ecology), biomass: they generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion metric tons of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans. The Protist shell, shells of dead diatoms can reach as much as a half-mile (800 m) deep on the ocean floor, and the entire Amazon basin is fertilized annually by 27 million tons of diatom shell dust transported by transatlantic winds from the African Sahara, much of it from the Bodélé Dep ...

Bacteriastrum
''Bacteriastrum'' is a genus of diatoms in family Chaetocerotaceae.Tomas, C. R., Hasle G. R., Syvertsen, E. E., Steidinger, K. A., Tangen, K., Throndsen, J., Heimdal, B. R., (1997). ''Identifying Marine Phytoplankton'', Academic Press. There are more than 30 described species in genus ''Bacteriastrum'', but many of these are not currently accepted, and new species are still added to the genus.Sarno, D., Zingone, A. & Marino, D. (1997). ''Bacteriastrum parallelum'' sp. nov., a new diatom from the Gulf of Naples, and new observations on ''B. furcatum'' (Chaetocerotaceae, Bacillariophyta). Phycologia 36: 257-266 The type species for the genus is '' Bacteriastrum furcatum'' Shadbolt. Description ''Bacteriastrum'' is a widely distributed marine, planktonic genus. This genus is often associated with ''Chaetoceros'' but differs in radial symmetry and fenestration of setae. The colonies tend to lie in girdle view, and the cells are separated by the curvature of the basal part of the set ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
