Beef Extract Agar
Used as a general-purpose nutrient medium that is able to support the growth of non-fastidious bacteria.
Catalog Number: AS-1134
To successfully cultivate a wide range of medically relevant microorganisms, culture media must closely mimic the conditions found within the human body. Beef Extract Agar is a versatile general-purpose medium that provides a suitable environment for the growth of both pathogens and commensals.
For the purpose of fermenting investigations and cultivating Candida species, Beef Extract Agar is recommended as a flexible medium. It contains carbon and nitrogen from the digestion of animal tissues and beef extract. Sodium chloride is also included as a source of electrolyte. This non-selective medium supports the growth of a variety of organisms important to medical research by simulating the physiological environment.
