Premium grade organic peptones and extract powders engineered to boost biomass yield and maintain raw material stability in laboratory and industrial bioreactors.
In modern industrial biotechnology, selecting the correct nitrogen source is a critical factor determining the success of cultivation. Tryptone (the pancreatic digest of casein) and Yeast Extract (the soluble autolysate of yeast cells) are two essential organic nitrogen raw materials. They provide complementary nutritional profiles.
Tryptone is rich in free amino acids and oligopeptides, particularly providing a high content of Tryptophan. This peptide-dominant nitrogen source ensures a steady release of nutrients, preventing osmotic shock and acid accumulation in rapid growth phases. Yeast Extract, on the other hand, acts as a growth-factor booster, rich in B-complex vitamins, nucleotides (purines and pyrimidines), organic acids, and essential trace minerals.
When combined, these two ingredients optimize the metabolic pathways of recombinant bacteria (such as Escherichia coli), yeast (such as Pichia pastoris), and mammalian cells. This combination directly increases the yield of target recombinant proteins, enzymes, and secondary metabolites.
Understanding the micro-nutritional variations helps bioprocessing engineers optimize medium formulation:
A modern high-tech enterprise integrating research and development, manufacturing, and global commercial trade of high-quality microbial culture media raw materials.
Established in 2008, Beijing Hongrun Baoshun Technology Co., Ltd. took root in the China (Beijing) Pilot Free Trade Zone Science and Technology Innovation Area. Over a decade of development, it has evolved into a national "High-tech Enterprise" and a "Zhongguancun High-tech Enterprise".
In 2018, the company strategically expanded its manufacturing footprint to the Qili Industrial Park in Langzhong, Sichuan. Phase I and Phase II factories cover an area exceeding 40,000 square meters. The plant operates separate, independent production lines for animal-derived and plant-derived products to prevent cross-contamination and meet non-animal formulation demands. Upholding a strict quality standard, we ensure that no substandard products leave the factory, supported by ISO9001:2015 and MUI Halal certifications.
The company maintains a strong collaborative force through its five dedicated subsidiaries:
Integrating our nitrogen and yeast formulations into critical industries to optimize batch consistency and biomass yield.
Tryptone and Yeast Extract form the basic components of standard media such as LB, Terrific Broth, and Super Broth. Our raw materials ensure clear solubility and minimal precipitate formation after high-temperature autoclaving.
Optimized for E. coli and yeast expressions. The low endotoxin levels and stable amino acid profile prevent cellular stress, increasing the yield of monoclonal antibodies, vaccines, and diagnostic enzymes.
Supports the cultivation of fastidious lactic acid bacteria (e.g., Lactobacillus, Bifidobacterium). High peptide content provides bioavailable nitrogen for rapid cell density buildup.
Cost-effective bulk peptones and yeast extracts supply industrial nutrients for producing biocontrol agents, mycorrhizae, and plant-growth-promoting rhizobacteria (PGPR).
Improves yield in amylase, protease, and lipase production. Designed to meet the requirements of large-scale bioreactors with consistent batch-to-batch performance.
Ensuring batch-to-batch repeatability of nitrogen sources through modern manufacturing technologies.
We use high-activity food-grade enzymes under strictly monitored pH and temperature profiles. This ensures controlled hydrolysis, resulting in target molecular weight distributions of peptides and free amino nitrogen.
Our raw materials undergo clean filtration and clarification stages to remove insoluble substances. The resulting powder dissolves clearly, minimizing residue build-up in downstream purification processes.
For bovine and casein-derived tryptone, we source strictly from verified, disease-free regions. For vegan peptones, we use non-GMO plant sources to comply with global regulatory standards.
Equipped with MUI Halal certification, our production lines follow strict standards. This allows our global partners to formulate products that meet various dietary and religious requirements.
