Description
DESCRIPTION
Gelatin peptone is a pancreatic digest of porcine skin. Pancreatic digestion produces a balanced mixture of amino acids, including essential amino acids, in optimal ratio with low molecular weight peptides.
It is low in fermentable carbohydrates and is used in culture media, especially for non-fastidious microorganisms. It is also used in fermentation studies.
