Shewanella violacea DSS12 (S. violacea) is a gram-negative bacterium located in marine sediment in the Ryukyu Trench at a depth of 5,110m.[1] The first description of this organism was published in 1998 by Japanese microbiologists Yuichi Nogi, Chiaki Kato, and Koki Horikoshi, who named the species after its violet[2] appearance when it is grown on Marine Agar 2216 Plates.[1]
Shewanella violacea is a motile rod-shaped bacterium with flagella.[3] It is a facultative anaerobic organism and considered an extremophile due to its optimal growing conditions at 8°C and 30 MPa.[4] Researchers are evaluating this species to better understand the specific mechanisms S. violacea uses in order to thrive in its unusually cold and high-pressure environment.
