Meat Peptone is an enzymatic digest of animal tissue. Meat peptones are proteins from animal sources that have been hydrolyzed or broken down into amino acids and peptides, to provide nitrogen for microorganisms. Meat peptones can be tailored to specific nutritive needs of microorganisms by controlling the quality and origin of the protein, the quality and source of the enzyme used to digest the protein, and the method used for hydrolysis, concentration and drying the peptone. It can be incorporated into a variety of liquid and solid culture media formulations for the cultivation of fastidious and non-fastidious microorganisms.
