Blue green algae growing on the substrate of a fresh water aquarium. 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".
Nodularia is a genus of filamentous nitrogen-fixing cyanobacteria, or blue-green algae. [1] They occur mainly in brackish or salinic waters, such as the hypersaline Makgadikgadi Pans, [2] the Peel-Harvey Estuary in Western Australia or the Baltic Sea. Nodularia cells occasionally form heavy algal blooms.
Edible blue-green algae reduce the production of pro-inflammatory cytokines by inhibiting NF-κB pathway in macrophages and splenocytes. [264] Sulfate polysaccharides exhibit immunomodulatory, antitumor, antithrombotic, anticoagulant, anti-mutagenic, anti-inflammatory, antimicrobial, and even antiviral activity against HIV, herpes, and hepatitis.
Pediastrum is a genus of green algae, in the family Hydrodictyaceae. [1] It is a photoautotrophic, nonmotile coenobial green alga that inhabits freshwater environments. The name Pediastrum comes from the Greek root words pedion, meaning "plane", and astron, meaning "star", referring to its overall shape.
Microcystins—or cyanoginosins—are a class of toxins produced by certain cyanobacteria, commonly known as blue-green algae. [3] Over 250 [4] different microcystins have been discovered so far, of which microcystin-LR is the most common. Chemically they are cyclic heptapeptides produced through nonribosomal peptide synthases. [5]
This group of viruses includes the original cyanophage isolate that infected "blue-green algae". [ 13 ] [ 3 ] Cyanophages in this group are easy to isolate from the environment. [ 3 ] They carry short non-contractile tails and cause lysis of several species within three genera of cyanobacteria: Lyngbya , Plectonema and Phormidium . [ 3 ]
Chlamydomonas (/ ˌ k l æ m ɪ ˈ d ɒ m ə n ə s,-d ə ˈ m oʊ-/ KLAM-ih-DOM-ə-nəs, -də-MOH-) is a genus of green algae consisting of about 150 species [2] of unicellular flagellates, found in stagnant water and on damp soil, in freshwater, seawater, and even in snow as "snow algae". [3]
Spirogyra (common names include water silk, mermaid's tresses, and blanket weed) is a genus of filamentous charophyte green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is characteristic of the genus. Spirogyra species, of which there are more than 500, are commonly found in freshwater ...
