They can help in promoting good health, some digestion and some serve medicinal purposes. Lactobacillis is a family of bacteria found in the human digestive tract. Acidophilus is a member of lactobacillis and it is the best known bacteria of this family aiding in the breakdown of lactose to lactic acid and also the breakdown of other sugars.
