Description

Hahella chejuensis KCTC 2396 is a Gram-negative, heterotrophic bacterium that thrives in aquatic environments. This organism exhibits a bacilli shape and possesses flagella, which contribute to its motility in water. It is classified as a facultative anaerobe, indicating that it can grow in both the presence and absence of oxygen, making it adaptable to varying environmental conditions. This bacterium is mesophilic, meaning it prefers moderate temperatures for optimal growth. It has a single replicon and is characterized by having two membranes, which is typical of Gram-negative bacteria. Hahella chejuensis is free-living and does not exhibit pathogenicity, suggesting it does not cause disease in other organisms. The ecological role of Hahella chejuensis may be significant in aquatic ecosystems, particularly in nutrient cycling and organic matter degradation due to its heterotrophic nature. By utilizing organic compounds as an energy source, it likely contributes to the maintenance of microbial diversity and the health of aquatic environments. The genomic data for this species is cataloged under accession number NC_007645.1, providing a resource for further research into its biological functions and ecological interactions.
