Overview

  • Pelomonas saccharophila, (aka Pseudomonas saccharophila), 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 69.1%. Pelomonas saccharophila is probably a rare gut coloniser. (Gomila2007; Xie2005)



  • This organism has been recovered from human faeces, and mud. 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.

  • NOTES
    Description of gen. nov.

    (Pe.lo.mo′nas. Gr. n. mud; Gr. n. a unit, monad; N.L. fem. n. a monad isolated from mud).

    Cells are Gram-negative rods, motile with one polar flagellum. Colonies are grey, round and opaque; old colonies (cultured for more than 2 weeks) are brown in nitrogen-free medium. Cells possess PHB granules as a storage material. Catalase and oxidase activities are present. Acid is produced from glucose. Positive reaction for gelatin liquefaction and starch hydrolysis but negative for denitrification, arginine dihydrolase and lipase. Able to fix nitrogen and show autotrophic growth with hydrogen but not photoautotrophy. The G+C content of the DNA is 69·1 mol%. Straight-chain 16 : 17, 16 : 0 and 18 : 17 are the major components of cellular fatty acids; 10 : 0 3-OH and 12 : 0 2-OH are the major hydroxy fatty acids. Ubiquinone-8 is the major component of the quinone system. The type species is .
