Description

General description

Casein Acid Hydrolysate is obtained by degrading casein with hydrochloric acid; vitamins and other growth-promoting compounds are largely destroyed in the process. However, it is a rich source of amino acids and serves as a nitrogen source. It is suitable for the preparation of culture media employed in the bacteriological assay of vitamins and antibiotic sensitivity.

Application

Casein Acid Hydrolysate that is free of vitamins can be used as a nitrogen source in culture media that is being used to conduct a bacteriological assay on vitamins and antibiotic sensitivity.

Other Notes

A hydrochloric acid digest of casein free of vitamins.
