Pseudoalteromonas arctica A 37-1-2

Pseudoalteromonas arctica A 37-1-2 is a Gram-negative, aerobic bacterium characterized by its rod shape. This organism is psychrotolerant, with an optimal growth temperature of 16°C, allowing it to thrive in cold environments. The genomic structure of P. arctica A 37-1-2 includes three replicons, which may contribute to its adaptability and resilience in various ecological niches. Notably, this strain is non-spore-forming, indicating it relies on other mechanisms for survival under adverse conditions rather than sporulation. P. arctica A 37-1-2 has been cataloged under several GenBank accessions, including NZ_CP011025.1, NZ_CP011026.1, and NZ_CP011027.1, which provide a basis for further genomic studies and potential applications in biotechnology. From a biological and ecological perspective, the psychrotolerant nature of P. arctica A 37-1-2 suggests its significant role in cold marine ecosystems, where it may contribute to nutrient cycling and organic matter degradation. Its ability to thrive at low temperatures enhances our understanding of microbial diversity in polar regions and the ecological processes that sustain these environments.
