Explore our foundational range of industrial peptones, yeast extracts, and biological growth factors designed for precision microbial fermentation.
Proteose Peptone No. 3 is a specialized enzymatic digest of animal tissues designed to meet the rigorous nutritional demands of fastidious microorganisms. Chemically, it stands apart from standard peptones due to its highly specific distribution of proteoses, peptones, peptides, and free amino acids. The digestion process uses selected enzymes to hydrolyze complex proteins, resulting in a nutrient-rich compound packed with molecular-weight fractions that are highly bioavailable to bacteria and fungi.
Crucially, Proteose Peptone No. 3 is enriched with high-molecular-weight proteose fractions. These fractions act as highly efficient protective colloids and cellular buffers in culture media, stabilizing physical environments during aggressive growth phases. Additionally, it offers a dense concentration of growth factors, trace minerals, and vitamins that cannot survive harsher acid hydrolysis processes. It is the gold standard for producing bacterial toxins, cultivating pathogenic organisms, and maintaining cell lines in bioprocesses.
"By precisely controlling the enzymatic hydrolysis curve, our manufacturing facilities ensure that every batch of Proteose Peptone No. 3 delivers consistent amino nitrogen levels, eliminating process variability in commercial biomanufacturing."
| Analytical Parameter | Standard Range | Proteose Peptone No. 3 Specification | Key Biochemical Function |
|---|---|---|---|
| Total Nitrogen (TN) | ≥ 10.0% | 12.5% - 14.5% | Essential elemental building block for cellular protein synthesis |
| Amino Nitrogen (AN) | ≥ 2.5% | 3.5% - 5.5% | Directly indicates the concentration of free amino acids and small peptides |
| Moisture Content | ≤ 6.0% | ≤ 5.0% | Ensures high physical stability and prevents hygroscopic clumping |
| Ash Value | ≤ 12.0% | ≤ 8.0% | Reflects low inorganic salt carryover, minimizing mineral toxicity |
| pH (2% Solution) | 6.0 - 7.5 | 6.8 - 7.2 | Physiologically balanced for bacterial cell viability |

Established in 2008, Beijing Hongrun Baoshun Technology Co., Ltd. is located in the Science and Technology Innovation Area of the China (Beijing) Pilot Free Trade Zone. Over the years, we have grown into a modern high-tech enterprise that integrates research, development, production, and sales. We are proud recipients of dual national honors as a "High-tech Enterprise" and a "Zhongguancun High-tech Enterprise."
In 2018, we expanded our production footprint by establishing a state-of-the-art facility in the Qili Industrial Park in Langzhong, Sichuan. Spanning over 40,000 square meters across Phase I and Phase II factories, and backed by a 20,000-square-meter storage facility, this expansion ensures a reliable, continuous raw material supply chain. With over 100 dedicated employees, our facility utilizes independent animal-source and plant-source production lines to avoid cross-contamination.
Our Operating Philosophy: "No substandard products leaving the factory." We monitor every step of production and perform comprehensive quality testing on all batches.
Our operations are supported by five core subsidiaries working in unison to provide seamless logistics, production, and research support:
Our raw materials support clean, efficient growth profiles across multiple biotechnology and industrial sectors.
Supplying essential animal, plant, and yeast nitrogen sources to support customized formulations for labs and factories alike.
Supplying raw materials that meet strict low-endotoxin and high-purity specifications for cell culture and therapeutics.
Providing high-yield nitrogen sources for industrial enzymes, organic acids, and bio-based polymer manufacturing lines.
Optimizing growth parameters for beneficial gut microbes used in health supplements and infant formulas.
Supplying nutrients for bio-pesticides and bio-fertilizers to help reduce agricultural reliance on synthetic chemicals.
Enhancing immunity and improving survival rates in aquatic feed formulations with highly digestible protein hydrolysates.
Cultivating specialized bacteria designed to degrade toxic compounds in wastewater treatment plants.
Optimizing spawn growth and reducing production cycle times in commercial mushroom growing operations.
Exporting key components like Proteose Peptone No. 3 requires navigating complex regulatory standards. To support our global clients, we maintain a complete compliance framework that matches strict international standards:
As the biotechnology sector transitions toward animal-free and chemically defined components, Beijing Hongrun Baoshun is focusing on new solutions. Our R&D division is developing yeast extracts and plant-based peptones (such as wheat, potato, and soy peptones) that match the growth characteristics of Proteose Peptone No. 3. This research helps our clients reduce animal-derived risks while maintaining high production yields.
