Lactobacillus acidophilus

Patent Pending Lactobacillus acidophilus (New Latin 'acid-loving milk-bacterium') is a species of gram positive bacteria in the genus Lactobacillus. L. acidophilus is a homofermentative, microaerophilic species, fermenting sugars into lactic acid, and grows readily at rather low pH values (below pH 5.0) and has an optimum growth temperature of around 37 °C (99 °F).[1] L. acidophilus occurs naturally in the human and animal gastrointestinal tract and mouth.
