Shewanella atlantica strain HAW-EB5

Shewanella atlantica strain HAW-EB5 is a Gram-negative, aerobic bacterium characterized by its rod shape and the presence of flagella. This strain is psychrophilic, thriving at an optimal temperature of 5°C, which positions it well within the cold-adapted environments commonly found in polar regions and deep-sea ecosystems. The genome of S. atlantica strain HAW-EB5 contains a single replicon, indicating a streamlined genetic organization typical of many members of the Shewanella genus. Furthermore, this strain is non-spore-forming, which suggests that it relies on other survival strategies to endure environmental stressors rather than entering a dormant spore state. The adaptability of Shewanella species to cold environments and their metabolic versatility allow them to play crucial roles in biogeochemical cycling, particularly in the reduction of metals and organic compounds in marine sediments. The ability to thrive at low temperatures while remaining metabolically active can significantly impact nutrient cycling in cold marine ecosystems, influencing microbial community dynamics and ecosystem health. Overall, the traits of Shewanella atlantica strain HAW-EB5 underscore its ecological significance, particularly in nutrient cycling processes in psychrophilic environments.
