Biological function of Bifidobacteria

Bifidobacteria are well know benefit bacteria,they play significant roles in the intestinal tract of infants.Although foetus lives in a sterile environment,bifidobacteria become the predominate organisms of the faecal flora by the end of first week after born.Bifidobacteria are known to exhibit inhibitory effects on many pathogenic organisms both in vivo and in vitro,including salmonella etc.,and also stimulative effect on intestinal peristalsis.Comparative studies on infants show greater N retention they gain more weight;bifidobacteria can synthesize vitamins,including thiamin,riboflavin,B6 and K etc.,and they can partially or completely inhibit the reduction of nitrate to nitrite by other intestinal organisms. Bifidobacteria may assist in re-establishing the normal gut flora balance which is accompanied by a reduction of ammonia and free phenols in the blood.Bifidobacteria and lactobacillus acidophilus leads to a modulation of the immunological response and a removal of cholesterol.
