Description and significance

Deinococcus geothermalis is a gram positive, thermophilic radiophile (1). It was isolated in hot springs in Naples, Italy and in Sao Pedro do Sul in Portugal. D. geothermalis propagates in a temperature range from 45 to 50 °C and a pH range of 4.5 to 8.5, experiencing optimal growth at 47 °C and a pH of 6.5. It forms spherical cells approximately 1.2 to 2.0 micro meters in diameter which amasses into orange-pigmented colonies (2). Deinococcus geothermalis is capable of reducing Fe (III)-nitrilotriacetic acid, U (VI), and Cr (VI). (1) It is these qualities that support the potential development of this bacterium for bioremediation of radioactive waste (1).

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?
