Species


	Pseudoalteromonas atlantica T6c

Description and significance

Describe the appearance, habitat, etc. of the organism, and why it is important enough to have its genome sequenced. Describe how and where it was isolated. Include a picture or two (with sources) if you can find them.

Pseudoalteromonas atlantica is a rod-shaped, motile, gram-negative bacteria that is found in the ocean world wide. It is chemoorganotrophic and is a biofilm-forming bacteria. It usually inhabits symbiotically with marine eukaryotic hosts, such as crabs and seaweed. The genome of Pseudoalteromonas atlantica was sequenced due to its production of acidic extracellular polysaccharide during biofilm formation that shows potential in element recycling, detoxification, and materials production.

Genome structure

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence? Does it have any plasmids? Are they important to the organism's lifestyle?

The size of its genome is 5.187007 megabases, and its GC content is 45%.

Cell structure and metabolism

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

Some important molecules it produce include acidic extracellular polysaccharide(EPS), enzymes that hydrolyze agar, alginate, and carrageenan(such as agarase), signalling molecules, such as homoserine lactones, and proteases. It produces EPS in large amounts in order to concentrate nutrients and provide substrates within its biofilm for other marine microorganisms. In order to do this, it gains energy by colonizing solid surfaces quickly, and using its secreted enzymes to process and take up substrates.

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.

It does not cause any disease.

Application to Biotechnology

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