Mô tả sản phẩm

DESCRIPTION:

Peptic Digest of Meat USP is used for the growth of yeasts and molds, enterobacteria, staphylococci, and numerous other microorganisms. After addition to blood agar, it favors the growth of pneumococci, as well as the production of characteristic hemolysis. Because of its high content of sulfur compounds, it is used for the detection of hydrogen sulfide producers.
