Overview

  • Saccharibacillus brassicae is a Gram-positive, spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 58.4%. Saccharibacillus brassicae is likely to be transient and not a long-term gut coloniser. (Jiang2020)



  • This organism has been recovered from kimchi cabbage seeds. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Borderline cold mesophile, so unlikely to be a gut coloniser.
