Overview

  • Pedomicrobium ferrugineum is a Gram-negative, non-spore-forming, aerobic, motile, filamentous bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 63-66.8%. Pedomicrobium ferrugineum is probably a rare gut coloniser. (Gebers1981; Gebers1988; Hirsch2005Bergey)



  • This organism has been recovered from human faeces, soils, and aquatic sources. 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. A possible gut commensal.

  • NOTES

    Can utilise ammonia as a sole source of N and urea to a lesser extent.  Utilises arginine directly and cholesterol weakly.  Gives variable results for the use of phenol and propanol.
