General description

Beef extract powder is a dehydrated extract of bovine tissue for use in preparing microbiological culture media. It is prepared from selected bovine tissues which are free from fat and sinew. Diverse media utilize beef extract, for example, yeast dextrose broth, Herrold′s egg yolk medium. This nutritional supplement provides a mixture of peptides, individual amino acids, nucleotides, organic acids, minerals, and vitamins.

Application

Beef Extract Powder is used in general purpose culture media and is recommended for use in the bacteriological examination of water, milk, and other materials, where the uniform composition of media is important.Beef Extract Powder is also relied upon for biochemical studies like fermentation reactions.
