Other research suggests that Streptococcus thermophilus can improve the nutritional value of foods by making micronutrients available to the host. This probiotic bacterium was originally isolated from the intestinal tract of humans. It composes a majority of the beneficial microflora which produce acids to retard colonization of putrefactive bacteria such as E. coli, Clostridium, and Salmonella. Common synonyms for this bacterium are Bacillus bifidus, Bacterium bifidum, Lactobacillus bifidus, and Lactobacillus parabifidus. This probiotic bacterium can inhabit the large intestine.
Research suggests that bifidobacteria species can improve the nutritional value of foods.
Bifidobacterium longum has been implicated in the expression of strong antitumor activity in the rat model. It was shown to regulate markers and reduce colon tumor outcome. This probiotic bacterium was originally isolated from the intestinal tract of human infants. This species is predominant in the feces of breast-fed infants. Like other bifidobacteria species, this organism can produce acids that may retard the colonization of the colon by certain foreign or harmful bacteria.
