Pleurocapsales
The Pleurocapsales are an order of coccooid cyanobacteria Cyanobacteria ( ) are a group of autotrophic gram-negative bacteria that can obtain biological energy via oxygenic photosynthesis. The name "cyanobacteria" () refers to their bluish green (cyan) color, which forms the basis of cyanobacteri .... Pleurocapsales are characterized by having boocytes, specialized cells where multiple fission takes place. Their ecology is mainly endolytic and calcareous, they are found inside rocks and in low light conditions. Pleurocapsales were thought to be related to ''Chroococcidiopsis'' but recent work with phylogenetics of the 16S rDNA gene has shown that ''Chroococcidiopsis'' belongs to its own order Chroococcidiopsidales. Some genera within Pleurocapsales form pseudo-ramifications such as ''Pleurocapsa'' sp., ''Odorella'' sp, and all the genera within the Hyellaceae family. Historically, the order Pleurocapsales has been one of the least studied orders of cyanobacteria, due t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyanobacteria
Cyanobacteria ( ) are a group of autotrophic gram-negative bacteria that can obtain biological energy via oxygenic photosynthesis. The name "cyanobacteria" () refers to their bluish green (cyan) color, which forms the basis of cyanobacteria's informal common name, blue-green algae. Cyanobacteria are probably the most numerous taxon to have ever existed on Earth and the first organisms known to have produced oxygen, having appeared in the middle Archean eon and apparently originated in a freshwater or terrestrial environment. Their photopigments can absorb the red- and blue-spectrum frequencies of sunlight (thus reflecting a greenish color) to split water molecules into hydrogen ions and oxygen. The hydrogen ions are used to react with carbon dioxide to produce complex organic compounds such as carbohydrates (a process known as carbon fixation), and the oxygen is released as a byproduct. By continuously producing and releasing oxygen over billions of years, cyanobacte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chroococcales
The Chroococcales () are an order of cyanobacteria in some classifications which includes the harmful algal bloom '' Microcystis aeruginosa''. Molecular data indicate that Chroococcales may be polyphyletic, meaning its members may not all belong to the same clade or have the same common ancestor. Characteristics The order is characterized by single, floating cells or colonies which are embedded to a matrix. Also, a lack of differentiation between apical and basal structures exists. Prochlorales A heterotypic synonym of Chroococcales is (order) Prochlorales , with type genus "''Prochloron''". Additional names of the same nature included: * Division Prochlorophyta Lewin, 1976 * Class Prochlorophyceae Lewin, 1977 * Family Prochloraceae Lewin, 1977 * Chloroxybacteria Margulis & Schwartz, 1982 * Subdivision Prochlorobacteria Jeffrey 1982 * Division Prochlorophycota Shameel 2008 The assignment as a division/subdivision was based on a belief that because this class lack red and blue ...
