In industrial biotechnology and microbiological culture formulation, Bacto ™ Yeast Extract stands out as an irreplaceable organic nitrogen substrate. Synthesized from selected strains of *Saccharomyces cerevisiae*, yeast extracts undergo controlled autolysis—a natural process where the yeast cells' own enzymes break down complex intracellular structures into highly soluble proteins, essential peptides, free amino acids, vitamins, and minerals.
As leading **China Bacto ™ Yeast Extract Manufacturers**, our mission centers around delivering highly consistent, bio-available nutrition matrices that serve as the baseline growth media for vaccine production, therapeutic proteins, monoclonal antibodies (mAbs), and probiotics culture. Through precise temperature, pH, and enzyme regulation, we optimize the concentration of essential vitamins like the B-complex group and structural nucleotides (such as GMP, IMP), which act as biological growth factors for fastidious organisms.
Offers rich concentrations of peptides, purines, pyrimidines, and free amino acids, facilitating high cell-density growth curves.
Provides critical natural growth factors (Thiamine, Riboflavin, Niacin, Folic Acid) that accelerate metabolic pathways.
Engineered via automated processing to maintain strict batch-to-batch stability, reducing downstream purification variability.
Established in 2008 and rooted within the Science and Technology Innovation Area of the China (Beijing) Pilot Free Trade Zone, Beijing Hongrun Baoshun Technology Co., Ltd. has evolved into a premier high-tech enterprise. Integrating state-of-the-art research, advanced production control systems, and comprehensive international sales, the company holds dual certifications as a national **"High-tech Enterprise"** and a **"Zhongguancun High-tech Enterprise"**.
In 2018, we expanded our manufacturing operations by establishing a world-class production hub in the Qili Industrial Park in Langzhong, Sichuan. Spanning over 40,000 square meters of specialized production area alongside a 20,000 square meter logistics and warehousing facility, we guarantee continuous global supply capability.
With over 100 dedicated bio-engineers, technicians, and operations personnel, we operate entirely independent production lines for animal-derived and plant-derived (as well as yeast-derived) materials. This total separation prevents cross-contamination, ensuring full compliance with international safety and quality standards, including ISO 9001:2015 and MUI Halal.

The global demand for high-grade bioprocess nitrogen sources is surging, driven primarily by progress in recombinant DNA therapeutics, vaccine production, and precision fermentation. Industrial scaling demands yeast extracts of the highest purity to maximize cell yields while minimizing cell culture contaminants. Modern factories must adhere to standard chemical indices to support precision bioprocesses.
As experienced manufacturers, we maintain strict controls over our synthesis pathway. Below is the typical technical specification profile for our premium biological-grade yeast extract, showcasing the analytical details required for standard cell culture applications:
| Analytical Parameter | Specification Target Range | Testing Methodology / Standard |
|---|---|---|
| Total Nitrogen (TN) | ≥ 10.0% | Kjeldahl Method |
| Amino Nitrogen (AN) | ≥ 4.5% | Formol Titration |
| Moisture Content | ≤ 5.0% | Loss on Drying (105°C, 3h) |
| Ash Content | ≤ 15.0% | Muffle Furnace (550°C) |
| pH (2% Aqueous Solution) | 6.0 – 7.2 | Potentiometric measurement |
| Solubility (in Water) | 100% Rapidly Soluble (Clear, no residue) | Visual / Gravimetric |
| Endotoxins | Low Endotoxin Grade Available | LAL Gel Clot Assay |
Manufacturing yeast extract requires balancing temperature, enzymatic activity, and mechanical separation. The journey from food-grade yeast strains to a purified, spray-dried powder involves several critical phases:
Living yeast cells are placed in warm reactors. Plasmolysis agents stimulate autolytic enzymes, breaking down structural cell membranes and extracting soluble nitrogen fractions.
Using high-speed industrial centrifuges, insoluble cell walls (yeast hulls) are separated from the soluble fraction. Ultrafiltration loops remove large molecular proteins to produce a clear, refined liquid.
The liquid extract is concentrated via low-temperature falling film evaporators. Lastly, state-of-the-art spray drying towers turn it into highly hygroscopic, fast-dissolving powder.
To ensure complete compatibility with biopharmaceutical guidelines, our process strictly avoids non-biological chemical additions. We preserve the natural matrix of B-complex vitamins, nucleotide precursors, and trace elements, making the final powder highly compatible with cell cultures.
Our Bacto ™ Yeast Extract serves as a primary raw material across several critical industrial segments:
Used to support the industrial production of recombinant therapeutics, insulin, monoclonal antibodies, and vaccine antigens. It functions as an alternative to animal-derived peptones, helping to eliminate BSE/TSE risks.
Supports the cultivation of lactic acid bacteria, *Bifidobacterium*, and *Lactobacillus* species. Provides essential growth factors that improve viability during freeze-drying and fermentation.
Supplements nitrogen for bio-pesticide fermentation, including *Bacillus thuringiensis* and *Bacillus subtilis*. Promotes vegetative growth and spore yields in agricultural bioprocesses.
Acts as a standard nutrient base in microbiological diagnostic media, including LB Broth, Tryptic Soy Broth, and custom nutrient agars used in testing laboratories globally.
Provides amino acids and minerals to support the production of amylases, proteases, cellulases, and lipases used in feed, textile, and food processing applications.
Serves as a clean-label ingredient and fermentation substrate for biological preservatives (such as Nisin) that extend food shelf life naturally.
Biotechnical applications often require custom nutrient formulations. Slight variations in free amino acid ratios or molecular weight distributions can significantly affect yield and downstream processing.
