Although colloquially called algae, blue-green algae (BGA) is a type of cyanobacteria. It can present with several different colors. While there are many BGA species, the most common type found in aquaria is referred to as "slime algae". Infestations may attach to aquarium glass and substrates. It may commonly be of the genus Oscillatoria. [21]
The bubble flotation mechanism identified by Maeda et al. joins a range of known strategies that enable cyanobacteria to control their buoyancy, such as using gas vesicles or accumulating carbohydrate ballasts. [134] Type IV pili on their own could also control the position of marine cyanobacteria in the water column by regulating viscous drag ...
Algae (UK: / ˈ æ l ɡ iː / AL-ghee, US: / ˈ æ l dʒ iː / AL-jee; [3] sg.: alga / ˈ æ l ɡ ə / AL-gə) is an informal term for any organisms of a large and diverse group of photosynthetic eukaryotes, which include species from multiple distinct clades.
Marine cyanobacteria are to date the smallest known photosynthetic organisms; Prochlorococcus is the smallest at just 0.5 to 0.7 micrometres in diameter. [11] [2] The coccoid shaped cells are non-motile and free-living. Their small size and large surface-area-to-volume ratio, gives them an advantage in nutrient-poor water.
Algae eater or algivore is a common name for any bottom-dwelling or filter-feeding aquatic animal species that specialize in feeding on algae and phytoplanktons.Algae eaters are important for the fishkeeping hobby and many are commonly kept by aquarium hobbyists to improve water quality. [1]
Oscillatoria is a genus of filamentous cyanobacteria. It is often found in freshwater environments. [1] Its name refers to the oscillating motion of its filaments as they slide against each other to position the colony to face a light source. [2] Oscillatoria uses photosynthesis to survive and reproduce.
Aphanizomenon are a special type of cyanobacteria called heterocysts, which are capable of producing biologically useful nitrogen by the process of nitrogen fixation from atmospheric nitrogen. A large proportion (between 35 and 50%) of fixed nitrogen may be released into the surrounding water, providing an important source of biologically ...
Swim bladder disease, also called swim bladder disorder or flipover, is a common ailment in aquarium fish. The swim bladder is an internal gas-filled organ that contributes to the ability of a fish to control its buoyancy, and thus to stay at the current water depth without having to waste energy in swimming.
