Lactobacillus Selective Agar Base is used for the isolation and enumeration of lactobacilli in a laboratory setting. Lactobacillus Selective Agar Base is not intended for use in the diagnosis of disease or other conditions in humans. Lactobacillus Selective Agar Base was developed by Rogosa, Mitchell, and Wiseman. This medium is used for isolation, enumeration, and identification of lactobacilli in foods. The low pH and high acetate concentrations effectively suppress other bacterial flora allowing lactobacilli to flourish.
