Fish peptone, a light yellow to yellowish fine powder, is derived from fresh fish bones through advanced biological extraction methods. Produced by a meticulous process that includes raw material cleaning, enzymatic hydrolysis, centrifugal separation, decolorization, purification, vacuum concentration, and spray drying, this product efficiently breaks down fish bone protein into small peptides and free amino acids. The result is a high-purity powder with excellent solubility, retaining vital water-soluble active substances, As a premium organic nitrogen source, fish peptone is rich in small molecular peptides, free amino acids, trace elements, and growth factors. This makes it rapidly absorbable and usable by microorganisms, promoting cell proliferation, protein synthesis, and metabolic enzyme activity. Consequently, it significantly enhances strain growth density and fermentation stability, making it an ideal choice for various applications, Fish peptone is widely utilized in microbial fermentation, vaccine production, and the development of biological products and industrial fermentation processes. When paired with yeast extract, malt extract, and other medium components, it optimizes nutrient matching and boosts the expression of target products. Our fish peptone is a popular choice among suppliers and factories in China, serving diverse needs in scientific research and industrial production environments
