Premium bulk nitrogen sources, peptones, and customized extracts formulated directly from our ISO 9001 certified manufacturing facilities.
Yeast extract is a key source of nitrogen for biotechnology. Producing it at an industrial scale requires careful biochemical controls to ensure high nutrient content and batch consistency. At Hongrun Baoshun, our process begins with high-purity cultures of Saccharomyces cerevisiae. We grow these cultures using controlled carbon-to-nitrogen feed systems to maximize intracellular nitrogen storage, amino acid levels, and vitamin yields.
We transform this yeast biomass into soluble nutrients using two main methods: natural autolysis and targeted enzymatic hydrolysis. During autolysis, the yeast cells are heated under controlled conditions. This activates the yeast's own digestive enzymes—such as proteases, peptidases, and nucleases—which naturally break down the cell walls. In enzymatic hydrolysis, we add food-grade enzymes to speed up this process. This helps us customize the mix of free amino acids, peptides, and nucleotides to meet specific industrial requirements.
| Process Parameter | Autolytic Process Route | Enzymatic Hydrolysis Route | Key Biochemical Significance |
|---|---|---|---|
| Primary Catalyst Source | Endogenous yeast intracellular enzymes | Added food-grade proteases & peptidases | Determines peptide distribution and product yield |
| Degree of Hydrolysis (DH) | Moderate (35% – 50%) | High (Up to 75% +) | Drives solubility, clarify, and bacterial cell uptake |
| Free Amino Nitrogen (FAN) | 2.5% – 4.5% | 4.5% – 6.5%+ | Essential indicator for growth rate optimization |
| Nucleotide Enrichment (I+G) | Natural distribution | Enzymatically enriched up to 20% | Synergistic cofactor for demanding fermentations |
Industrial scale-up is challenging. Our products are formulated to solve common bottlenecks in bioprocesses and culture media preparation.
We monitor our raw materials and processing steps closely to prevent batch-to-batch variation, helping protect your fermentation yields.
Our filtration removes insoluble residues, creating solutions that remain clear after autoclaving to reduce filter clogging in downstream steps.
Our raw plant materials are sourced from non-GMO crops. The entire processing line meets MUI Halal and ISO 9001:2015 standards, making it ready for global use.
In 2018, Hongrun Baoshun expanded its operations to the Qili Industrial Park in Langzhong, Sichuan. This site features Phase I and Phase II factories covering over 40,000 square meters, supported by a 20,000 square meter storage warehouse. This facility allows us to process animal-derived, plant-derived, and yeast-derived materials on separate, independent lines.
This separation prevents cross-contamination, supporting our Halal and animal-free production standards. We manage production through an integrated control system that tracks extraction temperature, pH levels, and spray-drying heat. This automated tracking helps us deliver consistent quality across large wholesale volumes.
Our yeast extracts and peptones are used across diverse fields, from vaccine production to industrial environmental bioremediation.
Our yeast extracts supply the amino acids, B vitamins, and trace elements needed for dehydrated and plated media formulations.
These products provide nitrogen sources for manufacturing biopharmaceuticals, including vaccines, therapeutic proteins, and monoclonal antibodies.
They help optimize biomass yields and maintain survival rates for beneficial bacteria like Lactobacillus and Bifidobacterium during freeze-drying.
Our media support high-yield cell growth for producing industrial amylases, proteases, and cellulases.
They serve as nutrients in biopesticides and biofertilizers, promoting the growth of soil bacteria like Bacillus thuringiensis.
Used to grow specific bacterial blends for wastewater treatment and the bioremediation of contaminated soil.
Different microbes require different nutrition. Our R&D team can customize nitrogen profiles, peptide distributions, and moisture levels to suit your specific strains. We offer free evaluation samples up to 500g (shipping fees excluded).
Exporting biotechnology materials requires meeting strict compliance and quality standards. Our manufacturing lines follow the policy of "no substandard products leave the factory". We operate under double certifications as a national "High-tech Enterprise" and a "Zhongguancun High-tech Enterprise."
Our quality management is certified to ISO 9001:2015, ensuring traceablity from raw materials to final shipment. We also hold MUI Halal Certification to support food and pharmaceutical markets worldwide. Backed by our five specialized subsidiaries—Beijing Yaoyou Technology, Sichuan Baoshun Biotechnology, Sichuan Romgee Biotechnology, Sichuan Yingwen Technology, and Sichuan Runxiaobao Technology—we manage the full supply chain to ensure consistent, timely deliveries.
Common questions from biotechnology and procurement teams regarding our manufacturing, certifications, and product handling.
Our yeast extract powder is spray-dried, leaving a moisture content below 5.0%. This gives it a long shelf life and makes it easy to handle in dry mixes. Our yeast paste contains 20% to 30% water, making it a cost-effective option for large-scale liquid fermentations where dry handling isn't necessary.
We maintain MUI Halal certification through clear segregation of our manufacturing lines. We run animal-derived materials and plant-derived/yeast materials on separate production machinery in our Langzhong facility, preventing cross-contamination.
Yes, all raw wheat and soy materials are certified non-GMO. We verify this through identity preservation testing at the farm level, ensuring compliance with strict international regulations.
We can adjust key chemical properties to match your needs. This includes modifying free amino nitrogen (FAN) ratios, changing nucleotide concentration, controlling mineral levels (such as sodium and chloride), and adapting bulk density for better powder flow.
We use automated processing controls to manage temperature, pH, enzyme levels, and concentration. Every batch undergoes final testing using HPLC and nitrogen analyzers to confirm it fits within our tight specification range before shipment.
Standard products ship in 1 to 2 weeks from our 20,000 square meter warehouse. For customized formulations, production and shipping preparation takes 3 to 4 weeks. We ship worldwide in secure, double-layered, moisture-resistant packaging.
