- 論文の詳細を見る
We have isolated a difructose anhydride III (DFA III)-assimilating bacterium, Ruminococcus productus AHU1760, from human. After an acclimation period of 1 week, male Sprague-Dawley rats (5 weeks old) were divided into four groups (control diet, R. productus diet, DFA III diet, and R. productus + DFA III diet; n=8) and fed the assigned test diets for 2 weeks. The viable count of administered R. productus was 4.9×107 CFU/d in R. productus-fed rats and 4.7×107 CFU/d in R. productus + DFA III-fed rats. Survival in cecal content of this strain was confirmed by randomly amplified polymorphic DNA. The ratio of secondary bile acids in feces in R. productus + DFA III-fed rats decreased the same as that in rats fed only DFA III. The viable count of lactobacilli and bifidobacteria, known as beneficial bacteria, increased more in R. productus + DFA III-fed rats than in control or R. productus-fed rats. A combination of R. productus and DFA III might improve the balance of intestinal microbiota to a healthier condition.
