Halodesulfovibrio aestuarii W218

Halodesulfovibrio aestuarii W218 is a free-living, rod-shaped bacterium characterized by its Gram-negative cell wall and the presence of flagella. This organism is classified as a facultative anaerobe, which allows it to thrive in both aerobic and anaerobic environments. H. aestuarii W218 has an optimal growth temperature of 32°C, placing it within the mesophilic range, indicating its preference for moderate temperatures. The bacterial cells are arranged as singles, which is notable for its growth form. H. aestuarii W218 has a single replicon, which is a characteristic of certain bacterial genomes, simplifying its genetic architecture. Unlike many motile bacteria, H. aestuarii W218 does not exhibit mobility despite having flagella, suggesting that its locomotion may be limited or functionally different from other flagellated species. The ecological significance of H. aestuarii W218 lies in its ability to adapt to varying oxygen levels, allowing it to occupy diverse ecological niches. Its free-living nature suggests it may play a role in nutrient cycling within its environment, potentially participating in processes such as the degradation of organic matter or the transformation of sulfur compounds. The accession number CP192218.1 provides a reference for further genomic studies that may elucidate its metabolic pathways and interactions within microbial communities. Understanding the traits of H. aestuarii W218 can contribute to our knowledge of microbial diversity and its implications for ecosystem functioning.
