SOYBEAN CASEIN DIGEST MEDIUM (as per USP/EP/JP/BP)

Soybean Casein Digest Medium is recommended as a sterility testing medium in accordance with the harmonized method of USP/EP/BP/JP/IP. It is used for the sensitivity testing of antimicrobial agents by the tube dilution method. It is also employed in diagnostic research in microbiology. Soybean Casein Digest Medium is used as a diluent and suspending medium for preparation of samples or test strains. It is also employed in sample preparation for testing of products, wherein incubation is carried out, only to serve sufficient resuscitation of the cell, while avoiding multiplication of the organism. The combination of Pancreatic digest of casein and Papaic digest of soybean makes Soybean Casein Digest Medium nutritious by providing nitrogenous, carbonaceous compounds, long chain amino acids, vitamins and other minerals for the growth of microorganisms. Natural sugars in soybean promote growth of fastidious organisms. Glucose monohydrate is the fermentable source of carbon and di-potassium hydrogen phosphate serves as the buffer in the medium. Sodium chloride maintains the osmotic balance of the medium.

The Soybean Casein Digest Medium has a broad application in sterility test and for total aerobic microbial count in the validation samples. It allows microorganism recovery without excessive bacterial growth for controlled testing conditions. The use of the medium as recommended supports consistent results under the recommended storage conditions.
