Lactobacillus acidophilus is a gram positive bacterium. Is is most commonly a rod shape.

     It grows in or without the presence of oxygen, is able to live in highly acidic environments of pH 4-5 or lower and is characterized as a homofermentative; produces lactic acid as its sole product.

It is naturally found in the human and animal GI(Gastrointestinal) tract and mouth

Classification:

Lactobacillus acidophilus is often sold in health stores in pill or powder form as a nutritional supplement. Research on the nutritional benefits of taking L. acidophilus supplements is inconsistent and inconclusive. Most such claims boil down to a link between L. acidophilus and a possible decrease in the incidence of certain diseases, including yeast infections, gastrointestinal disorders, and a weakened immune system. Most researchers agree further study is needed before substantiating many of these claims.
