COLWELLIA PSYCHRERYTHRAEA
| Class: | Gamma Proteobacteria |
| Genus: | Colwellia |
| Species: | Colwellia psychrerythraea |
| Description: | Colwellia psychrerythraea is considered an obligate psychrophile, Gram-negative bacteria, and appears rod-shaped and red in pigment. This flagella-containing organism can be found in continually cold marine environments including Arctic and Antarctic sea ice. Strain 34H, in particular, 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. |
