Oscillatoria filaments

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. Each filament of Oscillatoria consists of a row of cells called a trichome. The tip of the trichome oscillates like a pendulum.

Reproduction takes place asexually by fragmentation. 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.[1]

As a result of recent genetic analyses, several new genera were erected from this genus, e.g. Tenebriella.[3]

Research

[edit]

Oscillatoria are the subject of research into the natural production of butylated hydroxytoluene (BHT),[4] an antioxidant, food additive, and industrial chemical.

Cyclic peptides called venturamides, which may have anti-malarial activity, have been isolated from bacteria in this genus. They are the first peptides with this activity to have been found in cyanobacteria.[5]

Serinolamide A is a cannabinoid structurally related to Anandamide that has been found to occur in Oscillatoria species.[6]

Species

Oscillatoria contains the following species:[7]
