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.
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.
Preparation Note
Recommended concentration: 25 g/L
Analysis Note
A mixture of free amino acids with virtually no unhydrolyzed peptides. Only minimal inorganic components are present.
