Query: NC_009524:1796000 Psychrobacter sp. PRwf-1 chromosome, complete genome Lineage: Psychrobacter; Psychrobacter; Moraxellaceae; Pseudomonadales; Proteobacteria; Bacteria General Information: This organism grows slower than Psychrobacter arcticus 273-4 at 4 degrees C, but is capable of growth at 37 degrees C, while strain 273-4 is not. Psychrobacter is a member of the gamma Proteobacteria family. This genus is commonly isolated from cold environments, including soil, sea-ice, and the skin and gills of fish. It has also been associated with food spoilage and is often resistant to irradiation used for food preservation. Psychrobacters have also been identified from a variety of human sources. The strain Psychrobacter sp. PRwf-1 was isolated from the skin and gills of Lutjanus vivanus caught off the coast of Loíza in northeastern Puerto Rico.

General Information: This organism was isolated from a 2-3 million-year permafrost core in Siberia, Russia and can survive and grow rapidly at low temperatures. Analysis of long-term survival of psychrophilic organisms such as this one may aid understanding of the potential growth of organisms in astrobiology. Exiguobacterium sibiricum is a psychrotolerant organism able to grow at temperatures that range from -6 to 40 degrees C. This organism is also able to survive repeated freeze/thaw cycles which may contribute to its ability to survive in cold environments.
