Lactobacillus acidophilus

Lactobacillus acidophilus is a rod-shaped, gram-positive, anaerobic bacterium first isolated from infant feces in 1900. It is commonly found in the human gastrointestinal tract and oral cavity, and in fermented foods such as fermented milk and yogurt, though it is not the most common species used for that purpose. It grows best at low pH and has an optimum growth temperature of 37 degrees Celsius. Certain strains show strong probiotic effects and are used commercially in dairy production, and the species genome has been fully sequenced.
