Premium organic nitrogen sources, peptones, and plant/animal protein extracts designed for commercial microbial growth and culture media formulation.
Aureobasidium Pullulans, a ubiquitous polymorphic fungus commonly referred to as "black yeast," has captured the focus of modern biotechnology. Through precise microbial fermentation, this organism synthesizes a range of secondary metabolites, most notably Aureobasidium Pullulans Ferment Extract and the extracellular homopolysaccharide known as pullulan. Due to its outstanding biocompatibility, film-forming attributes, and powerful antioxidant capabilities, the ferment extract has emerged as a cornerstone ingredient across the global cosmetics, personal care, pharmaceutical, and biochemical engineering landscapes.
In industrial fermentation systems, the yield and purity of the bio-polymer are highly dependent on the quality of organic nitrogen, trace elements, and carbohydrates supplied to the cell cultures. Leading production systems rely on specialized raw materials such as yeast peptone, potato extract, and beef extract powder to satisfy the demanding nutritional requirements of Aureobasidium Pullulans. These inputs support optimized metabolic pathways, facilitating the high-yield synthesis of pullulan and active beta-glucans.
The ferment extract contains a rich spectrum of natural compounds: extracellular polymalic acid (PMA), complex beta-glucans, pullulan polysaccharides, essential free amino acids, and natural vitamins. Together, these elements deliver deep epidermal hydration, cell renewal support, and protective moisture barriers in advanced skincare formulations.
The worldwide market for bio-fermented ingredients is experiencing rapid growth, driven by consumer demand for clean-label, bio-based, and cruelty-free ingredients. In North America, the European Union, and East Asia, regulatory restrictions on synthetic polymers have accelerated the transition to natural film-formers. Consequently, the commercial demand for Aureobasidium Pullulans Ferment Extract has risen.
Beyond cosmetics, this extract is utilized in food technology as an edible coating to preserve the shelf-life of fresh produce, and in pharmaceuticals for the production of starch-free, vegan capsules. As environmental regulations tighten, industries are substituting fossil-fuel-based polymers with biodegradable alternatives derived from Aureobasidium Pullulans fermentation, establishing this microorganism as a core asset in the circular bio-economy.
China's industrial biotechnology sector stands out for its high production capacity, advanced processing technology, and integrated raw material supply chains. Factories in China leverage state-of-the-art infrastructure and cost-effective raw materials to produce high-purity biological extracts at a global scale.
Real-time telemetry and automated nutrient feed systems.
Direct sourcing of agricultural raw materials for peptone synthesis.
Fast dispatch networks from coastal and pilot free-trade zones.
Separate production lines to prevent batch cross-contamination.
By operating massive, integrated facilities, Chinese manufacturers minimize batch-to-batch variation while maintaining highly competitive pricing structures. Standardizing complex downstream purification steps—such as ultrafiltration, carbon decolorization, and spray drying—allows China's factories to deliver ingredients that consistently meet international standards.
Established in 2008, Beijing Hongrun Baoshun Technology Co., Ltd. is located in the Science and Technology Innovation Area of the China (Beijing) Pilot Free Trade Zone. Over the past two decades, the company has grown into a modern high-tech enterprise integrating research, development, production, and global sales. Recognized as both a national "High-tech Enterprise" and a "Zhongguancun High-tech Enterprise," Hongrun Baoshun is a trusted name in the bioprocessing industry.
In 2018, we expanded our production footprint by establishing state-of-the-art facilities in the Qili Industrial Park in Langzhong, Sichuan. Spanning Phase I and Phase II development, the Sichuan complex features a production area exceeding 40,000 square meters and a 20,000 square meter storage facility. Equipped with dedicated, independent production lines for animal-derived and plant-derived products, the facility manufactures specialized microbial culture media components, peptones, and yeast extract powders.
The biological properties of Aureobasidium Pullulans Ferment Extract make it a versatile ingredient for a variety of applications:
In skincare, the extract forms a breathable, microscopic film over the epidermis. This film helps prevent trans-epidermal water loss (TEWL) and shields the skin from environmental stressors. Additionally, the beta-glucans in the extract stimulate fibroblasts, encouraging collagen synthesis to minimize the appearance of fine lines and support natural skin repair.
Due to its rapid solubility and high structural stability, pullulan harvested from fermentation is used to produce pharmaceutical capsules. These capsules serve as a natural, vegan alternative to animal gelatin. They protect active compounds from oxidation, extending the shelf-life of moisture-sensitive drugs.
As an oxygen-barrier coating, the ferment extract provides a transparent, tasteless, and edible layer for food packaging. This coating reduces oxygen transmission, helping preserve the freshness of fruits, vegetables, and high-fat foods without the use of synthetic plastics.
In biological agriculture, the ferment extract is used to coat seeds and biological fertilizers. It improves the adhesion of microbial inoculants and beneficial bacteria to seeds, protecting them from dry soil conditions and promoting healthier crop development.
Looking forward, the industrial bio-fermentation sector is transitioning toward smarter, more sustainable practices. Researchers and manufacturers are focusing on metabolic engineering to optimize metabolic pathways, allowing Aureobasidium Pullulans strains to produce higher concentrations of targeted polymers.
Additionally, artificial intelligence is being integrated into production lines to monitor feeding rates, agitation speeds, and temperature changes in real time. This technology helps factories maximize yields and maintain consistent quality. By combining green energy with zero-waste processing, future bio-fermentation plants aim to minimize their environmental footprint while providing high-quality, bio-based ingredients to global markets.
