Complete genome sequence of Arcobacter nitrofigilis type strain (CI)

Area of Science:

• Microbiology
• Genomics
• Epsilonproteobacteria

Background:

• Arcobacter nitrofigilis is the type species of the Arcobacter genus, belonging to the Campylobacteraceae family.
• Originally identified as a nitrogen-fixing bacterium associated with Spartina alterniflora roots in marine environments.
• Its symbiotic marine lifestyle presents a phylogenetic contrast to other Arcobacter species often linked to warm-blooded animals and pathogenicity.

Purpose of the Study:

• To describe the features of Arcobacter nitrofigilis.
• To present the complete genome sequence and annotation of the Arcobacter nitrofigilis type strain.
• To contribute to the Genomic Encyclopedia of Bacteria and Archaea project.

Main Methods:

• Whole-genome sequencing of the Arcobacter nitrofigilis type strain.
• Bioinformatic analysis for genome annotation, including identification of protein-coding and RNA genes.

Main Results:

• The complete genome sequence of Arcobacter nitrofigilis was determined to be 3,192,235 bp.
• The genome contains 3,154 protein-coding genes and 70 RNA genes.
• This marks the first complete genome sequence for a type strain of the Arcobacter genus.

Conclusions:

• The genome sequence provides a foundational resource for understanding the biology and evolution of Arcobacter nitrofigilis.
• This work expands the genomic representation of Epsilonproteobacteria, particularly marine symbionts.
• The data facilitates comparative genomics and phylogenetic analyses within the Arcobacter genus.
