Fish Peptone

Fish Peptone

Using the deep-sea cod as the main raw material, the fish peptone is produced by enzymatic hydrolysis process and microorganism fermentation. The main components are small peptides (high content of nitrogen) and powder products of amino acid, and the content of small peptide is higher than that of bone peptone, making it easier for microbial absorption microbial growth acceleration.

Application

Widely used in the fermentation industry of antibiotics, vitamin, amino acid, organic acid, enzyme preparation and xanthan gum, providing organic nitrogen source of high quality for microbial fermentation.
