Cyanobacteria
Cyanobacteria (), also known as Cyanophyta, are a phylum of gram-negative bacteria that obtain energy via photosynthesis. The name ''cyanobacteria'' refers to their color (), which similarly forms the basis of cyanobacteria's common name, blue-green algae, although they are not usually scientifically classified as algae. They appear to have originated in a freshwater or terrestrial environment. Sericytochromatia, the proposed name of the paraphyletic and most basal group, is the ancestor of both the non-photosynthetic group Melainabacteria and the photosynthetic cyanobacteria, also called Oxyphotobacteria. Cyanobacteria use photosynthetic pigments, such as carotenoids, phycobilins, and various forms of chlorophyll, which absorb energy from light. Unlike heterotrophic prokaryotes, cyanobacteria have internal membranes. These are flattened sacs called thylakoids where photosynthesis is performed. Phototrophic eukaryotes such as green plants perform photosynthesis in plasti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichodesmium
''Trichodesmium'', also called sea sawdust, is a genus of filamentous cyanobacteria. They are found in nutrient poor tropical and subtropical ocean waters (particularly around Australia and in the Red Sea, where they were first described by Captain Cook). ''Trichodesmium'' is a diazotroph; that is, it fixes atmospheric nitrogen into ammonium, a nutrient used by other organisms. ''Trichodesmium'' is thought to fix nitrogen on such a scale that it accounts for almost half of the nitrogen fixation in marine systems globally. ''Trichodesmium'' is the only known diazotroph able to fix nitrogen in daylight under aerobic conditions without the use of heterocysts. ''Trichodesmium'' can live as individual filaments, with tens to hundreds of cells strung together, or in colonies consisting of tens to hundreds of filaments clustered together. These colonies are visible to the naked eye and sometimes form blooms, which can be extensive on surface waters. These large blooms led to wide ...

Annamia (cyanobacteria)
''Annamia'' is a small genus of gastromyzontid loaches native to Southeast Asia. There are two species, though one of them is of doubtful validity and identity: * ''Annamia normani'' (Hora, 1931), found in the Mekong basin * ''Annamia thuathienensis'' H. D. Nguyễn & V. H. Nguyễn, 2005, found in Vietnam (''species inquirenda In biological classification, a ''species inquirenda'' is a species of doubtful identity requiring further investigation. The use of the term in English-language biological literature dates back to at least the early nineteenth century. The term t ...'')
