Description and significance
Deinococcus radiodurans, meaning "strange berry that withstands radiation", is a Gram-positive aerobic bacteria classified as a member of the family Deinococcaceae. Forming reddish-pink colonies, the bacterium take the diplococci form (clusters of two cells) in early growth stages and the tetracocci form (clusters of four cells) in later stages of growth. Nicknamed, "superbug" and "Conan the Bacterium" (by Guinness World Book or Records), D. radiodurans is the most radiation-resistant vegetative cell, resisting radiation in the megarad range. Like many great discoveries, D. radiodurans was discovered accidentally in 1956 by Arthur W. Anderson during a laboratory experiment at the Oregon Agriculture Experiment Station (Corvalis, Oregon, US). While seeking new methods for preserving package meat, Anderson noticed bacterial growth after ground meat had been sterilized with radiation.
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.
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?
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?
