Description and significance

Colwellia psychrerythraea is considered an obligate psychrophile and appears rod-shaped and red in pigment. This flagella-containing organism is found mainly in sea ice. Strain 34H was isolated from Arctic marine sediments. It has a growth temperature range of -1°C to 10°C. Optimal growth appears at 8°C, with maximum cell yield occurring at the subzero temperature of -1°C. Cells are able to swim in temperatures as low as -10°C. Growth can occur under deep sea pressures as well.

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

The complete genome of Colwellia psychrerythraea 34H has been sequenced and shown to be 5,373,180 nucleotides in length. The genome consists of one circular chromosome which codes for 117 structural RNAs and 4910 proteins. The circular DNA contains 38% guanine-cytosine base pairing.
