Overview

  • Stenotrophomonas bentonitica is a Gram-negative, non-spore-forming, aerobic, non-motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 66.5%. Stenotrophomonas bentonitica is likely to be transient and not a long-term gut coloniser. (SanchezCastro2017)



  • This organism has been recovered from bentonite formations, Spain. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Aerobic and optimum growth temperature of 28C suggests this is an unlikely gut coloniser.
