本工作的目的是调查在体外木聚糖发酵过程中的相互关系之间的H-2和丁酸生产木聚糖分解的物种最近在我们的实验室中分离出的人类粪便，并确定为罗斯拜瑞氏菌和H-2利用产乙酸瘤胃球菌hydrogenotrophicus或产甲烷菌Methanobrevibacter smithii。H-2在M. Smithii或Ru。证明了氢营养型和木聚糖分解型微生物之间的相互作用，证实了这些H-2消耗型微生物在肠道中纤维发酵期间再利用发酵H2的巨大潜力。此外，乙酸转移之间的木聚糖分解罗斯拜瑞氏菌属和产乙酸的物种，这两种代谢物转移导致丁酸发酵燕麦木聚糖没有生产的H-2。
The aim of this work was to investigate in vitro interrelationships during xylan fermentation between an H-2 and butyrate-producing xylanolytic species recently isolated in our laboratory from human faeces and identified as Roseburia intestinalis and the H-2-utilizing acetogen Ruminococcus hydrogenotrophicus or the methanogen Methanobrevibacter smithii. H-2 transfer between M. smithii or Ru. hydrogenotrophicus and the xylanolytic species was evidenced, confirming the great potential of these H-2-consuming microorganisms to reutilize fermentative H2 during fibre fermentation in the gut. In addition, acetate transfer was demonstrated between the xylanolytic Roseburia sp. and the acetogenic species, both metabolites transfers leading to butyric fermentation of oat xylan without production of H-2.
