Overview


  • Romboutsia timonensis is a Gram-positive, spore-forming, strictly anaerobic, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. Romboutsia timonensis is a common gut coloniser. (Ricaboni2016)



  • This organism has been recovered from human faeces (Ricaboni2016). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.

  • QUIRKS
  • In 78% of Europeans (unseenbio.com).

  • SPECIAL FEATURES
    Character Response

  • NOTES

    Metabolites produced:
    Our genomic analysis indicates that most members of this species can produce the following metabolites: acetate, ammonia, butyrate, hydrogen sulphide, lactate, cobalamin, biotin.

    Metabolites consumed:
    In addition, our genomic analysis indicates that most members of this species do not consume any reported metabolites.

    The exploration of the human microbiome was recently revolutionized by microbial culturomics and taxonogenomics. Thanks to this approach, we report here the main characteristics of Romboutsia timonensis strain Marseille-P326, a new bacterium isolated from the right human colon by colonoscopy in a 63-year-old French man with severe anaemia with melaena.
