Overview

  • Georgenia satyanarayanai, (aka Oceanitalea nanhaiensis), is a Gram-positive, non-spore-forming, strictly aerobic, non-motile, oval-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 73.4%. Georgenia satyanarayanai is likely to be transient and not a long-term gut coloniser. (Kampfer2016; Srinivas2012; Fu2012)



  • This organism has been recovered from soda lake sediment, India. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Obligate aerobe; unlikely to be a gut coloniser. Data for antibiotic activity from Oceanitalea nanhaiensis (Fu2012).
