High-concentration animal, plant, and yeast nitrogen sources optimized for biotech, laboratory, and industrial growth systems.
Rooted in the science & technology innovation hub of the China (Beijing) Pilot Free Trade Zone, Beijing Hongrun Baoshun Technology Co., Ltd. has evolved into a premier high-tech enterprise integrating R&D, precision manufacturing, and international commerce.
Holding dual honors as a national "High-tech Enterprise" and a "Zhongguancun High-tech Enterprise", we focus on delivering stable, top-grade bioprocess ingredients. Our strategic expansion in 2018 established a massive 40,000-square-meter manufacturing footprint at Langzhong, Sichuan. Powered by specialized production pathways for animal, plant, and yeast processing, we offer tailored solutions to meet the demanding requirements of global bioscience sectors.
Uncompromising capacity and precision engineering for international bio-industries
A deep technical overview of adsorption purification, nutrient preservation, and performance enhancement in microbial fermentations
In high-precision industrial biotechnology, standard yeast extract, though nutritionally rich, presents challenges like pigmentation, heavy trace minerals, and background autofluorescence. Charcoal Yeast Extract resolves these issues by using active carbon filtration during autolysis. Active charcoal acts as a highly selective adsorbent, trapping large hydrophobic pigments, complex phenolic colorants, and trace inhibitors without stripping essential free amino acids, small peptides, vitamins, or growth-promoting trace elements.
Active charcoal treatment eliminates melanoidins and caramelization products formed during thermal extraction. This yields an exceptionally clear, pale filtrate that reduces down-stream purification complexity and avoids interference in analytical optical assays.
It selectively binds heavy metal ions, organic degradation products, and hydrophobic compounds that can retard the growth of sensitive bacterial strains, cell lines, and delicate recombinant protein expressions.
Our manufacturing process uses carefully controlled temperatures and precise enzyme mixtures to break down primary cultures of *Saccharomyces cerevisiae*. The resulting yeast extract is rich in organic nitrogen compounds. By using charcoal purification, we retain these compounds in highly bioavailable forms:
For global biotech companies, maintaining a stable supply chain is essential. Operating from Langzhong, Sichuan, we combine raw material access with scale to ensure reliable delivery.
By segregating our plant and animal processing lines, we eliminate cross-contamination risks and simplify international regulatory compliance. Our facilities feature:
Helping global procurement managers navigate complex quality standards and import requirements
Our operations follow ISO 9001:2015 standards, ensuring traceablity from raw materials to final shipment. We also hold MUI Halal certification, supporting compliance for global food and pharmaceutical products.
Through our five active subsidiaries, we manage global shipping, customs clearance, and local warehousing. We offer flexible shipping arrangements (FOB, CIF, DDP) to maintain consistent lead times.
Our multilingual technical team helps customers optimize culture media recipes, resolve fermentation performance changes, and request custom specifications (e.g., specific molecular weight distributions or salt limitations).
We provide custom development services to adjust nitrogen levels, mineral profiles, and physical properties (powder, granulated, paste) to match your manufacturing needs.
Decolorized charcoal yeast extract supports growth across multiple biotechnology and biochemical applications
Essential nutrient base for diagnostic agar, pharmaceutical quality control plates, and research culture formulations.
Supports cell growth for therapeutic proteins, vaccines, and monoclonal antibodies (mAbs).
Used in organic acid synthesis, bio-preservative production, and commercial amino acid fermentations.
Enhances strain viability and biomass density for *Lactobacillus*, *Bifidobacterium*, and other probiotic cultures.
Nutrient component for bio-pesticides, organic soil conditioners, and active bacterial fertilizers.
Industrial biotechnology is shifting toward animal-free, chemically defined, or highly purified organic nitrogen options to avoid BSE/TSE risks and simplify purification. Charcoal-treated yeast extracts are increasingly used as a reliable alternative to bovine-derived media components, meeting high performance and safety standards.
