|
In order to investigate the effects of food materials toward the growth of Bifidobacterium spp. and Clostridium perfi-ingens which have great influences on the intestinal physiology of human, 162 kinds of foodstuffs and foods were collected. Among their extracts, 31 samples showed the inhibitory effects against the growth of B. btfidum and C. perfringens by agar diffusion method. Especially, the methanol extracts of Caltha palustris, Deonjang, onion, mustard and potato inhibited the growth of C. perfringens, while they did not remarkably inhibit other intestinal bacteria including Bifidobacterium spp. By the cultivation of faecal inoculum in the 1 %(v/v) extract broths of Caltha palustris, onion and mustard, population of Bifidobacterium spp. increased by 10 order and that of C. perfringens decreased. βglucuronidase activities and indole amounts in the cultures of onion and mustard extracts were lower than those of the control culture and β-glucosidase activities were not detected in the cultures of onion and Doenjang extracts.
