Nodularia spumigena is a filamentous, planktonic, photosynthetic, diazotrophic, bloom-forming cyanobacterium.It is usually found in salty or brackish waters.

Description and Significance
Nodularia spumigena is a filamentous, planktonic, photosynthetic, diazotrophic, bloom-forming cyanobacterium.It is usually found in salty or brackish waters. It is one of the dominating species during the extensive cyanobacterial blooms in the Baltic Sea, which are one of the largest in the world. It is also found in Lake Alexandrina, in the south-east of southern Australia. The first documented outbreak was recorded by Francis in 1878. It is commonly found near the surface of the water because is has a high tolerance of ultraviolet radiation.
Genome Structure
The genome sequencing is currently underway at the Gordan and Betty Moore Foundation Microbial Genome Sequencing Project, but it not yet finished. The DNA length is 5,316,258 nt (5 Mb). The G-C content is 42.0%. There are 4860 genes coded for and 80% of the genome is coded. The number of chromosomes and shape of the genome is not yet known.
Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces.
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
