Genus species

Description and significance

Tricodesmium is a genus of cyanobacteria that is found in tropical and subtropical ocean waters with low nutrient levels. This genus is of great interest because it has been found to contribute over 40% of all nitrogen fixation that occurs in the ocean. In addition, there has been evidence that Trichodesmium blossoms can have a toxic effect on invertebrates and humans. Trichodesmium erythraeum is one of the two species of the Trichodesmium genus and occur as filaments of 20-200 cells. These filaments often congregate to form larger colonies that can be seen by the naked eye.

Genome structure

Has a circular genome that is 7750108 nucleotides long. This includes 4451 genes and 48 RNA genes.

Cell structure and metabolism

Describe any interesting features and/or cell structures; how it gains energy; what important molecules it produces.

Ecology

Describe any interactions with other organisms (included eukaryotes), contributions to the environment, effect on environment, etc.

Pathology

How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.

Application to Biotechnology

Does this organism produce any useful compounds or enzymes? What are they and how are they used?
