Cyanobacterial Motility
Cyanobacterial motility is the ability of cyanobacteria to motility, move independently using metabolic energy. Cyanobacterial motility, primarily through Gliding motility, gliding, Twitching motility, twitching, or buoyancy regulation, is an important adaptation for navigating heterogeneous environments, optimizing resource acquisition, and supporting community dynamics. The ability to move independently can enhance survival, colonization, and ecological interactions. It comes with trade-offs, including high energy costs, limited speed, and environmental dependencies. These characteristics reflect cyanobacteria's evolutionary balance between mobility and resource conservation in diverse habitats, from marine ecosystems to soil crusts. Types of movement No known cyanobacteria possess flagella. However, other types of movement occurring on solid surfaces include twitching, gliding and sliding, which are all independent of flagella. Twitching Twitching motility is a form of ... [...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] |
