Casein peptone is used in nutrient media for growing bacteria and fungi. It is employed in antibiotics and enzyme productions. It is also essential for analytical microbiology and industrial fermentation process. It is also used in bacterial diagnostics and in agro-food, cosmetic and pharmaceutical fermentation for production of biomass.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
