Overview

  • Brevibacterium iodinum is a Gram-variable, non-spore-forming, aerobic, non-motile, pleiomorphic bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 63%. Brevibacterium iodinum is likely to be transient and not a long-term gut coloniser. (Collins1980)



  • This organism has been recovered from cheese and human faeces. 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
  • Borderline cold mesophile, so unlikely to be a gut coloniser.
    • GENERAL CHARACTERISTICS (Collins1980);
    Character Response
  • Substrates hydrolysed or digested:
  • DNA; gelatin;
  • 🌡
  • Temperature tolerance:
  • grows weakly at 5℃; grows at 30℃; grows weakly at 37℃; Grows optimally at 25℃.
  • Active enzymes:
  • catalase; esterase C4; esterase lipase C8; Leu arylamidase; oxidase; pyrrolidine arylamidase;
