Paludisphaera borealis str. PX4

Paludisphaera borealis strain PX4 is a Gram-negative, aerobic, non-motile bacterium characterized as an organotroph and chemotroph, utilizing organic compounds for energy. It displays a spherical shape and thrives optimally at a temperature of 16°C, indicating its psychrotolerant nature, which allows it to grow in cooler environments. The strain is notable for having a single replicon, which is significant in its genetic organization and replication processes. The genomic information for Paludisphaera borealis str. PX4 is cataloged under the accession number NZ_CP019084.1, providing a reference for further genetic and functional studies. Given its psychrotolerant characteristics and the ability to utilize organic compounds for energy, Paludisphaera borealis str. PX4 is likely adapted to cold marine environments. This ecological niche suggests that it may play a role in the degradation of organic materials in polar or deep-sea ecosystems, contributing to nutrient cycling and energy flow within these habitats. This insight emphasizes the importance of such microorganisms in maintaining ecological balance in colder aquatic environments.
