Abstract:
:The effect of fructans on the cultivable faecal community of Bio Breeding rats fed diets containing 5% (m/v) food-grade fructooligosaccharide (FOS) was investigated. Culturing of faecal material using chicory inulin as the sole carbohydrate source revealed the presence of a greater diversity of inulin-utilizing bacterial species in FOS-fed rats as compared with the control rats, although both contained species which effectively utilized inulin. The majority of cultivable inulin-utilizing species fell within the Clostridium coccoides group and Clostridium leptum subgroup, some of which were related to previously cultured butyrate-producing bacteria from the intestines of various animals. The impact of FOS on the growth of the indigenous bifidobacteria community and three inulin-utilizing isolates was assessed using real-time polymerase chain reaction. While dietary FOS was found to stimulate the growth of all three inulin-utilizing isolates, no growth stimulation of the indigenous bifidobacteria community occurred over the duration of the feeding trial.
