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

,

This product is a light yellow powder derived from fresh bovine meat or bones, processed through acid or enzyme hydrolysis and then dried. It features a distinctive meat aroma. The protein is broken down using acid, alkali, or protease to create peptone, which is rich in organonitrogen compounds, vitamins, and sugars. This mixed peptone, sourced from beef and ox bone, is a complex blend of peptides and amino acids. The partial hydrolysis or enzymatic breakdown of larger proteins results in smaller molecules that are more accessible for microorganisms and cells compared to intact proteins. This nutritional base is essential for various applications, including research, diagnostic testing, and industrial fermentation processes.

,

Peptone is commonly used in media for culturing laboratory strains such as Escherichia coli and Salmonella. It plays a vital role in the fermentation industry, contributing to the production of antibiotics, vitamins, amino acids, organic acids, and enzyme preparations. Additionally, it is employed in drug sensitivity detection media and the cultivation of salt-tolerant microorganisms.

Frequently Asked Questions
Q1 What are the available grades of this product, and how do they differ?
The product is available in three grades: Industrial Grade, Pharmaceutical Grade, and Reagent Grade. They differ primarily in total nitrogen content (≥13.0% for industrial vs. ≥13.5% for the other two), amino nitrogen content (≥2.5% for reagent grade vs. ≥2.0% for the others), and solubility characteristics — pharmaceutical and reagent grades are pellucid in 2% solution, while industrial grade is only slightly soluble.
Q2 Can the product specifications be customized to meet specific requirements?
Yes. The physicochemical index listed represents a general specification. We can customize the product according to the specific requirements of each customer, including adjustments to nitrogen content, moisture levels, and other parameters.
Q3 How should the product be prepared before use?
The product must be fully dissolved and sterilized before use. Please ensure proper dissolution procedures are followed to achieve optimal performance and safety in your application.
Q4 What packaging options are available for this product?
The product is available in Compound Paper Bags (25kg/bag) or Cardboard Buckets for standard grades. Reagent-grade products are packaged in 250g plastic bottles. Custom packaging quantities and OEM packaging solutions are also available upon request.
Q5 What is the physical appearance and color of the product?
The product appears as a powder with no caking. Its color ranges from light yellow to yellow-brown. It carries the endemic taste and odor characteristic of the product, with no other peculiar smell, and contains no normal visible extraneous impurities.
Q6 What is the pH range of this product in solution?
The pH of a 2% solution of this product falls within the range of 4.5 to 7.5, applicable across all three grades — Industrial, Pharmaceutical, and Reagent. This mildly acidic to near-neutral range makes it suitable for a wide variety of applications.
