Casein hydrolysate (acid hydrolyzed) for vitamin media
EMD Cat. No. 1.02238.0500
500 g
The hydrolysate is obtained by degrading
casein with hydrochloric acid; vitamins and other growth-promoting compounds are largely destroyed in
this process. This hydrolysate is thus suitable for the preparation of culture media employed in the
bacteriological assay of vitamins. It is not suitable as the only substrate for the indole test.
A BSE-free certificate is available
upon request.
