Overview

  • Leuconostoc holzapfelii is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, oval-shaped bacterium. The DNA G+C content is 43.5%. Leuconostoc holzapfelii is probably a rare gut coloniser.



  • This organism has been recovered from fermented coffee, Ethiopia. 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. A possible gut commensal.
