acumedia<sup>®</sup> Yeast Extract

acumedia® Yeast Extract

• Intended Use: Yeast Extract is an autolysate of yeast cells used in preparing microbiological culture media.
• Product Summary and Explanation: 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. The yeast is harvested, washed, and resuspended in water, where it undergoes autolysis, i.e., self-digestion using the
yeast's enzymes. Yeast Extract is the total soluble portion of this autolytic action. The autolytic activity is stopped by a heating
step. The resulting Yeast Extract is filtered clear and dried into a powder by spray drying.
