General description

Soy peptone is a non-animal peptone that contains a broad range of nutrients. It is characterized by its high concentration of vitamins and carbohydrates. Its nitrogen content combined with the naturally occurring vitamins and high carbohydrate content facilitates rapid and profuse growth of fastidious microorganisms, as well as resuscitation of sub-lethally injured microorganisms. Its high content of fermentable sugars makes soy peptone unsuitable for fermentation studies, such as in media used for the identification of microorganisms based on sugar fermentation.


Soy peptone is used in cell culture, molecular genetic media, for microbiological assay procedures, and as a nutritive substrate for cultivation and resuscitation of a large variety of microorganisms.
