Thioploca araucae
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.
Thioploca araucae is a filamentous sulfur-oxidizing bacterium. It is typically found in bacterial mats in sediment layers at the bottom of the ocean. Thioploca has been found off the coast of Chile and Namibia, as well as in freshwater areas in Japan.
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 genome is currently being sequenced.
Cell structure and metabolism
Describe any interesting features and/or cell structures; how it gains energy; what important molecules it produces.
nitrate principal electron acceptor
link the sulfur and nitrogen cycles
Ecology
Describe any interactions with other organisms (included eukaryotes), contributions to the environment, effect on environment, etc.
Thioploca cells form filaments that cling to each other and secrete an encompassing sheath of mucous film. The sheath serves as a kind of vertical tunnel through the sediment up to the overlying water, allowing the Thioploca filaments to glide up and down and thereby commute between their food source and the nitrate they need to metabolize it.
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?
