Proteose Peptone

Proteose Peptone is a highly nutritious peptone. This product is prepared from a mixture of peptones rich in peptides with higher molecular weight. It is used as a nitrogen source in culture media formulated for isolating and cultivating fastidious and non-fastidious bacteria and fungi. In addition to its nitrogen constituents, this peptone has a high carbohydrate content and is suitable for many purposes. However, due to this high sugar content, it is not recommendable for fermentation assays.

Proteose Peptone is used for the cultivation of bacteria with high nutritional requirements. It is used for growth promotion and toxin production in a wide range of fastidious microorganisms like Corynebacterium diphtheriae, Staphylococci, Clostridia, and Salmonella. It is important to produce diphtheria toxoid, pertussis vaccine, and measles vaccine. It is also used in culture media for growing Neisseria, Haemophilus, Pasteurella, and Histoplasma species.
