The starter motor bacterium used in preparing fermented dairy farm farm merchandises have got to stay feasible at the clip of ingestion and capable of surviving in the intestinal piece of land to acquire upper limit benefits from it (fermented dairy product). These bacterium should also be able to set up in the intestinal epithelial tissue in ample figure by replacing occupant noxious pathogens. The above said statuses can almost be met by Bifidobacteria when compared to other starter motor cultures.
It is a well known fact that the fermented milk merchandises including bifidus milk are nutritionally superior and have got improved digestibleness and palatableness when compared to apparent milk but the curative benefits of the concerned bacterium in the fermented milk merchandises can be demonstrated in vivo only with feasible biomass of starter motors of human beginning viz. Lactobacillus and Bifidobacteria. Among the genus Bifidobacterium, the commonly used species in the production of bifidus milk are Bifidobacterium bifidum, B. infantis, B. longum, B. adolenscentis and B. animalis.
Morphological features and growing characteristics of Bifidobacteria
The bifidobacteria are gramme positive, perch shaped and anaerobic organisms. The morphology changes depending upon the strain and species. They are short, regular, thin cells with pointed ends or long cells with flimsy flex or protuberances. They may also be establish as baseball club shaped, or with spatulated appendages and also in star like arrangements.
The bifidobacterium is the normal dweller of the bowel of the babies fed with breast milk. Person milk turns out to be a good substrate for the growing of bifidobacteria owed to the presence of bifidus factor. Bifidobacteria of baby beginning such as as B. bifidum and B. infantis begin growing and acquire implanted in the intestinal epithelial tissue of babies if breast-fed.
As the babies turn and go child, the favourable bifidobacteria will be replaced by noxious bacteria. It can be inferred from the above statement that those babies fed with mother's milk are more than likely to have got the benefits from the bifidobacteria than those who are bottle-fed. The other option is to set up bifidus milk and addendum in the diet of babies and growing children.
