肠道微生物气体与肠道健康

he human gastrointestinal tract composes of a complex microflora，which is responsible for immunoregulation, the barrier effect, the metabolic and trophic function, and vitamin synthesis in human body. In this paper, we summarize the research progress of the intestinal microbes that can produce gas, especially methanogen and sulfate-reducing bacteria, introduce the biological mechanisms of gas production and discuss the relationship among intestinal microbes, generated gas and the pathogenesis of intestinal diseases, finally provide new strategies for research of intestinal microbes and gastrointestinal health.
