Overview

  • Sporolactobacillus nakayamae subsp. racemicus is a Gram-positive, spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. The DNA G+C content is 43-46%. Sporolactobacillus nakayamae subsp. racemicus is probably a rare gut coloniser. (Yanagita1997)



  • This organism has been recovered from soil and alcoholic breverage brewing, Japan. 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.
