CASEIN, ACID HYDROLYSATE
Lactic Acid Casein
Casein, Acid Hydrolysate is a hydrochloric acid hydrolysate of casein for use in preparing microbiological culture media.
Product Summary and Explanation
Casein is a rich source of amino nitrogen. Treatment with hydrochloric acid hydrolyzes the protein into primarily free amino acids with some short peptide fragments. Tryptophan and vitamins present in the casein are destroyed by the acid hydrolysis. The salt content of this peptone is very high at approximately 36%.
While this peptone is used in a number of microbiological media formulations, its main usage is in Mueller
Principles of the Procedure
Casein, Acid Hydrolysate is an acid hydroysate of casein. Casein, Acid Hydrolysate is an excellent source of free amino acids and short peptide fragments, which are required by microorganisms for growth.
