Overview

  • Slackia isoflavoniconvertens is a Gram-positive, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 58.5%. Slackia isoflavoniconvertens is probably a rare gut coloniser. (Matthies2009)



  • This organism has been recovered from human faeces. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
    • QUIRKS
  • Produces equol (an isoflavandiol aestrogen) from daidzein.
    • GENERAL CHARACTERISTICS (Matthies2009);
    Character Response
  • Active enzymes:
  • acid phosphatase; arginine dihydrolase; esterase C4; esterase lipase C8; naphthol-ASBI-P;
    • SPECIAL FEATURES (Matthies2009);
