Peptostreptococcales is an order of Gram-positive, endospore-forming, and predominantly strictly anaerobic bacteria within the class Clostridia.[1]
The order Peptostreptococcales encompasses three validly published families:[1]
- Anaerovoracaceae Chuvochina et al. 2023
- Natronincolaceae Chuvochina et al. 2023
- Peptostreptococcaceae Ezaki 2010 emend. Chuvochina et al. 2023
These families contain diverse anaerobic species widely distributed in animal-associated and environmental microbiomes.
Physiology and ecology
Peptostreptococcales members are anaerobic fermenters of carbohydrates and amino acids, often producing short-chain fatty acids such as acetate, butyrate, and propionate. Spore formation enables survival in challenging environments and facilitates transmission.
