DEFINITION

Lactobacillus acidophilus La-14 (ATCC strain designation SD5212) is a lactic acid-producing, Gram-positive, rod-shaped, non-motile, non-spore-forming bacterium that is homofermentative. Lactobacillus acidophilus La-14 occurs as a white- to cream-colored powder that is produced via fermentation of a pure, specific strain of Lactobacillus acidophilus. Suitable cryoprotectants may be added to the concentrated bacteria following fermentation, after which the product is frozen and then freeze-dried. The formulated product may be blended with suitable diluents and/or bulking agents. It contains NLT 100% of the labeled viable cell count of Lactobacillus acidophilus La-14.
