Complete genome sequence of Nitratifractor salsuginis type strain (E9I37-1)

Area of Science:

• Microbiology
• Genomics
• Environmental Science

Background:

• Nitratifractor salsuginis is the type species of the Nitratifractor genus within the Nautiliaceae family.
• The bacterium is notable for its efficient nitrate reduction to N(2), a crucial process in plant nutrition.
• It is also recognized as the first mesophilic, facultatively anaerobic Epsilonproteobacteria capable of growth on molecular hydrogen.

Purpose of the Study:

• To present the first completed genome sequence of a Nitratifractor genus member.
• To analyze the genomic features of Nitratifractor salsuginis, including its metabolic capabilities.
• To contribute to the Genomic Encyclopedia of Bacteria and Archaea project.

Main Methods:

• Whole-genome sequencing of Nitratifractor salsuginis.
• Bioinformatic analysis of the genome to identify protein-coding and RNA genes.
• Comparative genomics within the Nautiliaceae family.

Main Results:

• The genome sequence of Nitratifractor salsuginis has been completed, comprising 2,101,285 bp.
• The genome contains 2,121 protein-coding genes and 54 RNA genes.
• This represents the first genome sequence for the genus Nitratifractor and the second for the Nautiliaceae family.

Conclusions:

• The genome sequence provides insights into the metabolic potential of Nitratifractor salsuginis, particularly its nitrate reduction and hydrogen utilization pathways.
• This genomic data enhances our understanding of the Epsilonproteobacteria and the Nautiliaceae family.
• The study contributes valuable genomic information for research in microbial ecology and biogeochemical cycles.
