Overview


  • Thermaerobacter marianensis is a Gram-variable, non-spore-forming, strictly aerobic, non-motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 72.5%. Thermaerobacter marianensis is unlikely to be a gut coloniser. (Takai1999)



  • This organism has been recovered from the Mariana Trench. 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.

  • QUIRKS
  • Very high minimum growth temperature (50C) and strictly aerobic nature suggests this is a gut non-coloniser.
