General description

Proteose Peptone (vegetable) is an enzymatic hydrolysate of vegetable protein and therefore an animal-free alternative to traditional peptones. It is recommended for the cultivation of fastidious pathogens and can be employed in media or bulk production of antibiotics, enzymes, veterinary preparation, bacterial toxins, etc.

Application

Proteose Peptone (vegetable) facilitates the growth of a broad range of microbes, from fastidious aerobic bacteria to yeasts and molds. It is recommended for use in media that support good growth of a large number of microorganisms including Staphylococci, Streptococci, Pneumococci, Meningococci, and Gonococci, among others which require a highly nutritious medium.
