A compound required for the luxuriant growth of Lactobacillus sanfrancisco in laboratory media was isolated from a freshly prepared yeast extract, purified, and characterized. The stimulant was identified as a small peptide with a molecular weight of approximately 1,065, containing aspartic acid, cysteine, glutamic acid, glycine, and lysine.
