Abstract:The degradation products of homemade corn cob xylan degradation by thermophilic xylanase as raw material,with Bifidobacterium as main research object.The main research of oligosaccharide effecting to intestinal probiotics Bifidobacterium activity and value-added. Explore the oligosaccharide on intestinal probiotics Bifidobacterium activity and value whether has the effect of promoting. Research shows that,within certain range of concentration,corn cob xylanase hydrolysates on Bifidobacterium value-added role,different concentration different effects.
