Explore our industrial-grade organic nitrogen and peptide sources engineered for global biotechnology manufacturing.
In the fields of biopharmaceutical production, vaccine synthesis, diagnostic media preparation, and industrial enzyme expression, the selection of raw materials determines the efficiency, safety, and productivity of microbial processes. Among the various nitrogenous materials used, Bacto Proteose Peptone No 3 remains a critical nutrient source. This specialized peptone, derived from the enzymatic digestion of animal tissues, delivers a highly consistent mixture of proteoses, peptides, peptones, and free amino acids. It has become essential for cultivating demanding microorganisms and maximizing biomass yields in large-scale bioreactors.
This technical whitepaper covers the chemical makeup, manufacturing criteria, and industrial applications of Bacto Proteose Peptone No 3. It also highlights the global logistics networks, regulatory considerations, and production capabilities of Beijing Hongrun Baoshun Technology Co., Ltd., a leading supplier of microbiological culture media components.
Standard peptones provide simple nitrogenous nutrients. However, Bacto Proteose Peptone No 3 is processed under conditions that preserve larger peptide fragments (proteoses) alongside smaller peptides and essential trace minerals. This unique molecular distribution offers several advantages:
The molecular weight distribution includes a significant portion of medium-to-long chain peptides (500 to 3,000 Daltons). These function as crucial growth factors for demanding bacteria, such as Neisseria, Haemophilus, and Corynebacterium species.
It contains essential vitamins, purines, pyrimidines, and inorganic salts. These components work together to support metabolic pathways, eliminating the lag phase in bacterial culture growth.
The presence of complex proteoses provides a natural buffering capability, helping maintain stable pH levels in fermentation vessels without requiring constant chemical adjustments.
Specifically processed to dissolve quickly in water, it yields a clear solution that does not cloud during autoclaving, which is essential for accurate optical density monitoring.
Company Profile & Advanced Biotechnology Base
Established in 2008 and based in the China (Beijing) Pilot Free Trade Zone Science and Technology Innovation Area, Beijing Hongrun Baoshun Technology Co., Ltd. has grown into a modern high-tech enterprise. We integrate research and development, manufacturing, and sales to support the global biotechnology industry. We are recognized as both a national "High-tech Enterprise" and a "Zhongguancun High-tech Enterprise."
To support growing global demand, we expanded our footprint in 2018 to the Qili Industrial Park in Langzhong, Sichuan. Our combined Phase I and Phase II factories cover over 40,000 square meters, supported by a 20,000 square meter storage area. This allows us to ensure reliable supply, stable quality, and prompt shipping times for bulk orders.

Our operation is supported by five specialized subsidiaries that work together to coordinate research, production, and international logistics:
A primary challenge in utilizing Proteose Peptone No 3 is preventing lot-to-lot variation. We address this through a standardized process control system:
Our key operational advantages that ensure reliable supply and product consistency.
We supply a broad range of biological raw materials, including animal, plant (soy, wheat, potato), and yeast-derived peptones and extracts.
Our direct control over the manufacturing process, combined with a 20,000 square meter warehouse, ensures stable pricing and consistent delivery lead times.
Our quality assurance program guarantees that every shipment meets strict specifications for nitrogen content, moisture, ash, and clarity before leaving the facility.
We provide complimentary samples (up to 500g per product, excluding shipping costs) to allow technical teams to verify performance before ordering.
Different microorganisms have unique nutritional requirements. We work closely with our partners to design custom nitrogen sources tailored to specific bioprocess parameters. Our customization services cover:
Key information regarding Bacto Proteose Peptone No 3 applications and sourcing.
Proteose Peptone No 3 contains higher concentrations of proteoses, which are larger, partially hydrolyzed protein fractions. Unlike standard peptones that are broken down into simple peptides and amino acids, No 3 retains these larger structures. This provides essential protective growth factors and improved buffering capacity, making it ideal for delicate and demanding pathogens.
Many pathogenic bacteria, such as Corynebacterium diphtheriae, require specific nutritional signals to initiate toxin synthesis. The precise mix of peptides and trace minerals in Proteose Peptone No 3 triggers these metabolic pathways, leading to higher antigen and toxin yields compared to generic enzymatic digests.
Beijing Hongrun Baoshun strictly sources raw tissues from certified BSE/TSE-free countries and regions. Our manufacturing process includes heat treatment step-by-step sterilization, and we trace every lot back to its source. We run animal-derived materials on dedicated production lines separate from our plant-derived lines to prevent cross-contamination.
Our facilities are certified under the ISO 9001:2015 Quality Management System, and our products carry MUI Halal certification. We can provide full analytical documentation with every shipment, including Certificates of Analysis (COA), allergen reports, and safety data sheets (SDS).
We provide complimentary evaluation samples of up to 500 grams for established industrial users. Please contact our sales team with your project details, and we will prepare the sample from a lot that matches your specific process requirements.
