Overview

  • Fructilactobacillus sanfranciscensis, (aka Lactobacillus sanfranciscensis), is a Gram-positive, non-spore-forming, microaerophilic, 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 36-38%. Fructilactobacillus sanfranciscensis is probably a rare gut coloniser. (Kline1971; Rossi2016; Weiss1984)



  • This organism has been recovered from human faeces, food (fermented and spoilt) and sourdough bread fermentation. 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.
