LMG Agar is widely used in microbiology for the selective isolation and cultivation of lactic acid bacteria, particularly species from the genus Lactobacillus and related groups. It supports the growth of fastidious lactic acid bacteria due to its rich nutrient composition, including yeast extract, peptones, and carbohydrates. The medium can be modified with additives like acetic acid or cycloheximide to suppress unwanted bacterial or fungal growth, making it suitable for environmental, food, and clinical samples. It is commonly applied in dairy microbiology to monitor fermentation processes, identify probiotic strains, and ensure product quality in yogurt, cheese, and other fermented foods. Its reliability in supporting slow-growing strains makes it a standard choice in research and industrial labs focused on lactic acid bacteria characterization.
