Overview


  • Lysinibacillus varians is a Gram-positive, spore-forming, aerobic, motile, filamentous bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 43.2%. Lysinibacillus varians is probably a rare gut coloniser. (Zhu2014)



  • This organism has been recovered from waste-contaminated sediment in China. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
