China Yeast Peptone Suppliers: High-Quality Microbial Nitrogen Source from Factory for Amino Acid Fermentation

Yeast peptone is a premium biological nitrogen source derived from high-quality bread yeast in China. Produced through an advanced process involving autolysis, enzymatic hydrolysis, multi-stage separation, vacuum concentration, and spray drying, yeast peptone undergoes self-decomposition and enzymatic breakdown, transforming macromolecular proteins into readily absorbable small peptides and free amino acids, Rich in essential proteins, peptides, and amino acids, yeast peptone also contains a wealth of nucleotides, B vitamins, biotin, and various growth factors. These nutrients provide a comprehensive and balanced environment, effectively supporting the growth and metabolic activity of microorganisms, As a leading supplier in the industry, our yeast peptone is extensively utilized in microbial fermentation, biological preparations, and industrial fermentation applications. When used in conjunction with yeast extract and other medium components, it significantly enhances microbial growth and boosts metabolic activity. This results in a notable increase in fermentation efficiency and product yield, Choose our yeast peptone from a trusted factory in China to elevate your fermentation processes and optimize your product outcomes

? Frequently Asked Questions

Q1 What grades of yeast peptone are available?
Yeast peptone is available in three grades: Industrial Grade, Pharmaceutical Grade, and Reagent Grade. Each grade meets the same core physicochemical specifications, with differences in solubility and clarity requirements to suit different application needs.
Q2 Can the product specifications be customized?
Yes. While the physicochemical index represents our general specification, we can customize the product to meet specific requirements of individual customers. OEM packaging is also available upon request.
Q3 How should yeast peptone be prepared before use?
The product should be fully dissolved in water and then sterilized prior to use. This ensures optimal performance and safety in microbial culture applications.
Q4 What are the packaging options for yeast peptone?
Standard packaging options include Compound Paper Bags (25kg/bag) and Cardboard Buckets. Reagent-grade products are packaged in 250g plastic bottles. Custom packaging sizes and OEM packaging are also available to meet specific customer requirements.
Q5 What is the moisture content and pH range of yeast peptone?
The moisture content is ≤6.0% for all grades. The pH of a 2% solution falls within the range of 4.5–7.5, ensuring compatibility with a wide range of microbial culture media formulations.
Q6 What is the difference in solubility between Industrial Grade and Pharmaceutical Grade?
Industrial Grade yeast peptone is slightly soluble in a 2% solution, making it suitable for general microbial culture applications. Pharmaceutical Grade achieves complete lysis under the same conditions, while Reagent Grade is pellucid, offering the highest clarity and purity for analytical and research purposes.
