Clostridium butyricum

Clostridium butyricum is a species of rod-shaped bacteria belonging to the genus Clostridium. These bacteria are typically found in soil, water, and the intestinal tracts of animals. A key characteristic of most Clostridium species is their ability to thrive only in environments completely devoid of oxygen.1

C. butyricum is known to be involved in butyric fermentation, a process where certain anaerobic bacteria break down organic substances like lactic acid or butter to produce butyric acid. This fermentation can occur during putrefaction and in the digestive systems of herbivorous mammals. While some Clostridium species cause serious illnesses in humans and animals, such as botulism, tetanus, and gangrene, C. butyricum itself is primarily associated with fermentation processes.21
