Colwellia psychrerythraea str. ND2E

Colwellia psychrerythraea str. ND2E is a Gram-negative bacterium characterized by its rod shape and singular cell arrangement, which reflects its adaptation to specialized habitats. This psychrophilic organism thrives optimally at a temperature of 8.0°C, indicating a preference for cold environments, typical of polar or deep-sea ecosystems. As a facultatively anaerobe, Colwellia psychrerythraea str. ND2E possesses metabolic flexibility that allows it to utilize both aerobic and anaerobic respiration, thereby enhancing its survival in varying oxygen conditions. The organism's cold-adapted physiology and metabolic versatility suggest it plays a significant role in biogeochemical cycles in its native environments, potentially influencing nutrient cycling and organic matter decomposition in cold marine ecosystems. Its ability to thrive at low temperatures while accommodating fluctuations in oxygen availability positions Colwellia psychrerythraea str. ND2E as a key player in the microbial community dynamics of specialized habitats, where it may interact with other microorganisms and contribute to the overall ecological balance.
