Overview

  • Arthrobacter pigmenti is a Gram-positive, non-spore-forming, aerobic, non-motile, bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 61.2%. Arthrobacter pigmenti is unlikely to be a gut coloniser. (Heyrman2005)



  • This organism has been recovered from a Roman tomb painting. 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
  • Doesn't grow well at 37C, so probably a gut non-coloniser.
    • GENERAL CHARACTERISTICS (Heyrman2005);
    Character Response
  • Substrates hydrolysed or digested:
  • gelatin;
  • ±
  • Strain-dependent hydrolysis or digestion:
  • aesculin;
  • 🧂
  • Salt tolerance:
  • Grows optimally with 10% salt.
  • pH
  • Acidity tolerance:
  • tolerates pH 7; tolerates pH 10; Grows optimally at pH 8-9.
  • 🌡
  • Temperature tolerance:
  • doesn't grow at 37℃; Grows optimally at 22-30℃.
  • ±
  • Strain-dependent acid from carbs:
  • glucose; maltose; sucrose;
  • Active enzymes:
  • alkaline phosphatase; catalase; β-galactosidase; α-glucosidase; β-glucuronidase; Leu arylamidase; trypsin;
  • ±
  • Strain-dependent active enzymes:
  • β-glucosidase;
    • SPECIAL FEATURES (Heyrman2005);
    Character Response
  • ±
  • Nitrate:
  • strain dependent
  • Pigments:
  • light yellow
