Yeast Extract is the water-soluble portion of autolyzed yeast. The autolysis is carefully controlled to preserve naturally occurring B-complex vitamins. Yeast Extract is prepared and standardized for bacteriological use and cell cultures, and is an excellent stimulator of bacterial growth. Yeast Extract is generally employed in the concentration of 0.3% - 0.5%. Yeast Extract is typically prepared by growing baker’s yeast, Saccharomyces spp., in a carbohydrate-rich plant medium. Yeast Extract has been successful in culture media for bacterial studies in milk and other dairy products. Several media containing Yeast Extract have been recommended for cell culture applications.
