Overview

  • Fructilactobacillus florum, (aka Lactobacillus florum), is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, rod-shaped bacterium. The DNA G+C content is 42%. Fructilactobacillus florum is likely to be transient and not a long-term gut coloniser. (Rossi2016; Endo2010)



  • This organism has been recovered from from flowers, South Africa. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
