Overview


  • Pseudomonas alcaliphila is a Gram-negative, non-spore-forming, aerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 62.3-63.2%. Pseudomonas alcaliphila is probably a rare gut coloniser. (Yumoto2001)



  • This organism has been recovered from human faeces, and seawater. 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. A possible gut commensal.
