Overview

  • Chelatococcus asaccharovorans is a Gram-negative, non-spore-forming, strictly aerobic, non-motile, coccus bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 63.3-63.5%. Chelatococcus asaccharovorans is likely to be transient and not a long-term gut coloniser. (Auling1993)



  • This organism has been recovered from wastewater and soil. 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
  • Unable to grow with sugars. Strict aerobe, so unlikely to be a gut coloniser.
