China Peptone Organic Nitrogen Source for Industrial Fermentation - Suppliers and Factory Solutions

,

This product is a light yellow powder derived from fresh bovine meat and bones that have been hydrolyzed using acid or enzymes, followed by a drying process. It possesses a distinctive meat aroma, making it an ideal choice for various applications in biotechnology and microbiology. The protein content is carefully decomposed by acid, alkali, or protease to generate peptone, which is rich in organonitrogen compounds, vitamins, and sugars. Our mixed peptone, sourced from beef and ox bones, is a complex mixture of peptides and amino acids obtained through partial hydrolysis or enzymatic breakdown of larger proteins. This results in smaller, more bioavailable molecules that are essential for microorganisms and cells compared to whole proteins.

,

As a leading supplier in China, our peptone is commonly used in the production of culture media for culturing laboratory strains such as Escherichia coli and Salmonella. It plays a vital role in the fermentation industry for the production of antibiotics, vitamins, amino acids, organic acids, and enzyme preparations. Additionally, it is utilized in drug sensitivity detection mediums and the cultivation of salt-tolerant microorganisms. Trust our factory for high-quality peptone that supports your research and industrial processes efficiently.
