There are several salient features behind its popularity: lactobacilli are found naturally in the human gut; particularly common in the small bowel; grow in the absence of oxygen or small amounts of oxygen; they feed sugars as a source of carbon which are plenty in the intestine; require a range of minor nutrients to enable them to live and grow, as there is a wide range of food in that part of the intestine so they are prominent there.
