β-glucan, Bifidobacterium bifidum, modification, prebiotic, xylanase


Oat ?-glucan (BG) was isolated from oat bran, and the xylanase treatment was conducted to obtain modification of ?-glucan (MBG). The relative molecular weight  (Mw) of BG and MBG was determined by gel permeation chromatography  (GPC). Results demonstrated that the Mw of BG was reduced from 1.66×104 to 5.43×103. We assessed the prebiotic effect of BG and MBG on human colon Bifidobacterium bifidum?B. bifidum). Our findings suggest that the addition of BG and MBG resulted in a lower pH of the fermentation broths. Both lactic and acetic acid production increased in the fermentation broths. While BG was found to significantly promote the proliferation of B. bifidum, MBG had a greater effect on B. bifidum.
