Overview

  • Lactiplantibacillus pentosus, (aka Lactobacillus pentosus), is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 5 gut microbiome compilation studies or metastudies. The DNA G+C content is 46–47%. Lactiplantibacillus pentosus is probably a rare gut coloniser. (Rossi2016; Zanoni1987; Hammes2011Bergey)



  • This organism has been recovered from human faeces, blood, corn silage, fermenting olives, and sewage. 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.
