Acid hydrolyzed casein peptone

Acid hydrolyzed casein peptone

Description:This product is a light yellow to white dry powder obtained from casein, which is digested, decolorizing, filtering, concentrating and spray drying. Soluble in water, aqueous solution is pale yellow. It has a special flavor of soy sauce flavor. Casein, is a kind of phosphoprotein with high nutritional value extracted from milk. It is a common raw material for peptone production. The peptone produced from casein has quite complete amino acid, especially the content of tryptophan. Therefore, it is suitable for sugar fermentation and indole in the biochemical test of bacteria.

Range of application

1. The growth of anaerobic bacteria, fungi, pneumococcus, lactobacillus, corynebacterium, Clostridium and other bacteria such as water and milk testing;

2. Suitable for nitrate reduction test.
3. Used for the cultivation of protozoa and the detection of bacteriostasis or bactericide, antibiotics and other antibiotics, and the preparation of aseptic test medium. It is the basic raw material for biopharmaceutical fermentation and various media preparation. Its main function is to provide nitrogen sources and growth factors. The average dosage is 0.5% to 5%. 4. It is used as the raw material of culture medium to provide the nitrogen source and amino acid needed for bacterial growth. It is widely used in antibiotics, pharmaceutical industry, fermentation industry, biochemical products and microbiological research, and can be used to treat digestive tract diseases. The casein peptone hydrolyzed by acid is suitable for the growth and drug susceptibility test of diphtheria, pertussis, Streptococcus .
