Overview

  • Leuconostoc gelidum subsp. gasicomitatum is a Gram-positive, non-spore-forming, anaerobic, non-motile, coccus bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 37%. Leuconostoc gelidum subsp. gasicomitatum is unlikely to be a gut coloniser. (Rahkila2014)



  • This organism has been recovered from spoiled marinated broiler meat strips. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Inability to grow at 37C suggests this not a gut coloniser.
