Peptostreptococcus

RANK: Genus

TAXONOMY: Bacteria -> Terrabacteria group -> Firmicutes -> Clostridia -> Clostridiales -> Peptostreptococcaceae -> Peptostreptococcus

OVERVIEW:

Non-spore-forming obligately anaerobic Gram-stain-positive cocci. Cells may occur in pairs, irregular masses, or chains. Chemo-organotrophs. The optimum temperature for growth is 37°C. Metabolize peptone and amino acids to acetic, butyric, isobutyric, caproic, and isocaproic acid (Holdeman et al., 1986). Carbohydrates are weakly fermented. Found in human intestine, vagina, and various abscesses. Diamino acid of peptidoglycan is lysine.

DNA G+C content (mol%): 34–36.

Type species: Peptostreptococcus anaerobius

This genus contains microbial species that can reside in the human gastrointestinal tract. [PMC 4262072]
