摘要
产丁酸细菌是利用糖类发酵产生丁酸的一类细菌,代表种是丁酸梭菌。在动物及人类肠道内存在的产丁酸细菌主要是梭菌属、柔嫩梭菌属、罗斯式菌属、真菌属及丁酸弧菌属。本文一方面介绍部分肠道内产丁酸细菌的种类、特点及膳食纤维的摄入和肠道益生菌对产丁酸细菌的影响,另一方面对其主要代谢产物丁酸在体内的生理功能进行探讨,以期为产丁酸细菌的应用及产品开发提供理论依据。
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.
