Overview

  • Sporolactobacillus laevolacticus, (aka Bacillus laevolacticus), is a Gram-positive, spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 43-45%. Sporolactobacillus laevolacticus is likely to be transient and not a long-term gut coloniser. (Hatayama2006; Andersch1994; Nakayama1967)



  • This organism has been recovered from plant rhizospheres. 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.
