General description

Proteose-Peptone is a highly nutritious peptone. This product is prepared from a mixture of peptones which rich in peptides having 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 content of sugar, it is not recommendable for fermentation assays.

Application

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 for example Corynebacterium diphtheriae, staphylococci, clostridia and salmonellae. It is important for the production of diptheria toxoid, pertussis vaccine and measles vaccine and also used in culture media for growing Neisseria, Haemophilus, Pasteurella and Histoplasma species.
