Used as a growth medium in microbiological testing, particularly for the cultivation and maintenance of a wide range of microorganisms, including bacteria and fungi. It supports the growth of both aerobic and anaerobic organisms, making it suitable for sterility testing and microbial enumeration in pharmaceutical, cosmetic, and food industries. The absence of sodium chloride makes it ideal for culturing halosensitive organisms or for use in tests where salt interference must be avoided. Commonly used in validation studies and environmental monitoring due to its rich nutrient composition derived from soybean and casein digests.
