Description and Significance

Oscillatoria is a cyanobacteria that is important because it can conduct photosynthetic activities. It has a long un-braching filamentous morphology and is color green due to the chlorophyll it contains. Some unique features that sets it apart from other cyanobacteria is that it is motile and can conduct anoxygenic photosynthesis. [1]It does not require a heterocyst though, within its long filamentous structure the cells within it are in the form of discoid and are surrounded by cell wall so it does not require heterocyst. [2]

Structure, Metabolism, and Life Cycle

Oscillatoria is motile and moves by the means of microfibrils. They move in a gliding motion and tend to use this mobility to move towards light. Its gliding motion has a unique feature though, it moves in a oscillatory motion. [4] Oscillatoria has a long un-branching filamentous structure that reproduces by binary fission. [3] This cyanobacteria can conduct photosynthesis just like the other in its phylum but it can also conduct anoxygenic photosynthesis. Meaning that it can still obtain energy in the absence of oxygen, it can obtain it from the reduction of sulfate instead. This energy comes in the form of ATP and can be stored. [1]

Ecology and Pathogenesis

Natural habitat (soil, water, commensal of humans or animals?)
If relevant, how does this organism cause disease? Human, animal, or plant hosts? Important virulence factors, as well as patient symptoms.
