Lactobacagar - the differential nutrient medium that stimulates the growth of lactobacilli and inhibits extraneous microflora. The nutritional part of the environment consists of complex organic components (peptone, yeast extract), carbohydrate (glucose) and mineral supplements (magnesium, manganese). The precise composition optimal provides "picky" Lactobacillus nutrients in the required concentrations. When the salts of organic acids (acetate, citrate), and low pH inhibit the growth of extraneous microorganisms. This makes it possible to determine the presence of Lactobacillus in such planted samples as dairy and foods, or defecation. Samples cultured at 37 ° C for 48 hours to hold dishes with gasparatos providing the concentration of carbon dioxide 5-10%.
