Abstract:Butyrate-producing bacteria is a kind of bacteria which produce butyrate by fermenting carbohydrate, and its representative species is Clostridium butyricum. The main genus of butyrate-producing bacteria in the intestinal tract of animals and humans are Clostridium, Clostridium leptum, Roseburia, Eubacterium and Butyrivibrio. On the one hand, this paper introduces the species and characteristics of some butyrate-producing bacteria, effects of dietary fiber intake and intestinal probiotics on butyrate-producing bacteria. On the other hand, the physiological function of its main metabolite butyrate in vivo was discussed. In order to provide a theoretical basis for the application and product development of butyrate-producing bacteria.
