Overview


  • Sutcliffiella cohnii, (aka Bacillus cohnii), is a Gram-positive, spore-forming, aerobic, rod-shaped bacterium. The DNA G+C content is 33.5-35%. Sutcliffiella cohnii is likely to be transient and not a long-term gut coloniser. (Logan2011Bergey; Spanka1993)



  • This organism has been recovered from soil and faeces (Logan2011Bergey). 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. Robust growth can have positive consequences for gut health.

  • QUIRKS
  • Poor growth at pH7 so unlikely to be a gut coloniser.

  • GENERAL CHARACTERISTICS (Logan2011Bergey); (Spanka1993);
    Character Response
  • Substrates hydrolysed or digested:
  • casein; gelatin; hippurate; starch;

  • pH
  • Acidity tolerance:
  • doesn't tolerate pH 5.0; doesn't tolerate pH 6.0-7.0; tolerates pH >9.0;
  • 🌡
  • Temperature tolerance:
  • grows at 6(neg), 10℃; grows at 40℃; doesn't grow at 50℃;
  • H+
  • Acid from carbohydrates usually produced:
  • pullulan;
  • Substrates assimilated or utilised:
  • hippurate;
  • Active enzymes:

  • NOTES

    Able to hydrolyse 4-Methylumbelliferone glucuronide.  This artificial compound is usually used to detect the presence of the GUS enzyme found in E. coli.
