Analysis Note

A mixture of free amino acids with virtually no unhydrolyzed peptides. Only minimal inorganic components are present.

Application

Amicase® is used as a nutrient mixture in peptone agars for a variety of bacteria, including Bacillus subtilis, Enterobacter aerogenes, Escherichia coli, Saccharomyces cerevisiae, Staphylococcus aureus, Streptomyces pyogenes, and Streptomyces griseus.

General description

Amicase® is prepared by acid digestion of casein. It hasbeen used as a nutrient mixture in peptone agars for avariety of bacteria. It is manufactured under controlled condition by acid hydrolysis of milk protein. Vitamins and other growth promoting compounds are largely destroyed in the process. Hence it is suitable for the preparation of culture media employed in the bacteriological assay of vitamins and antibiotic sensitivity. Casein hydrolysates are used in the formulation of culture media with very high solubility and clarity in solution for the cultivation of heterotrophic microorganisms. It is used in laboratory media and fermentation, especially where high clarity of solution is required.

Preparation Note

Recommended concentration: 25 g/L

  4. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. How are the Amicase® (product A2427) and Hy-Case® SF (product C9386) different?

    The Amicase® (product A2427) and Hy-Case® SF (product C9386) are related items, but they are not exactly the same.  The Amicase® is prepared to keep the inorganic ions to a minimum so it is high in total nitrogen.  This is also the case for the Hy-Case® SF; however, this item is prepared to be essentially salt free (contains a maximum of 2.0% sodium chloride).  The Hy-Case® SF is recommended for use as a microbiological nutrient in laboratory media and fermentations, where a mixture of highly soluble free amino acids is required. It is especially recommended when inorganic ion levels need to be kept at a minimum.
