Oscillatoriafilaments

Oscillatoriais a genus of sugar making microscopic creatures.

It is afilamentouscyanobacteriumwhich is often found in freshwater environments and appears blue-green.[1]Its name refers to theoscillatingmotion of its filaments as they slide against each other to position the colony facing a light source.[2]Oscillatoriareproduces byfragmentation,facilitated by dead cells which separate a filament into separate sections, orhormogonia,which then grow.[1]Oscillatoriauses photosynthesis to survive and reproduce. Each filament of Oscillatoria consists of trichome[clarification needed]which is made up of rows of cells. The tip of the trichome oscillates like a pendulum. Reproduction takes place by vegetative means only. Usually the filament breaks into a number of fragments called hormogonia. Each hormogonium consist of one or more cells and grows into a filament by cell division in one direction.

Oscillatoriaare the subject of research into the natural production ofbutylated hydroxytoluene(BHT),[3]an antioxidant, food additive, and industrial chemical.

Cyclicpeptidescalled venturamides, which may have anti-malarialactivity, have been isolated from bacteria in this genus. They are the first peptides with this activity to have been found in cyanobacteria.[4]

Serinolamide Ais a cannabinoid structurally related toAnandamidethat has been found to occur in Oscillatoria species.[5]

As a result of recent genetic analyses, several new genera were erected from this genus, e.g.Tenebriella.[6]
