About Xuankai Biological

Nanjing Xuankai Biological Technology Co., Ltd. is a biotechnology company focused on industrial and synthetic biology for the research, development, and production of biopolymers. Founded in April 2010, the company originated from a collaboration between Nanjing Tech University and five of its academic staff: Xu Hong, Feng Xiaohai, Ouyang Pingkai, Cai Heng, and Li Sha. The company's development was built upon research from national programs, leading to the commercialization of its core products. The current de facto controllers are co-founders Xu Hong and Feng Xiaohai. Professor Xu Hong has a long-standing career in industrial biotechnology research at Nanjing Tech University, serving as the chief scientist for Jiangsu's key fermentation engineering discipline and has received numerous national and provincial science and technology awards. Feng Xiaohai also has a background as a researcher at the university and now serves as the company's general manager.

Xuankai Biological operates through R&D and production platforms focused on functional microorganisms, microbial secretions, and enzyme catalysis products. Its business model involves supplying raw materials and producing finished formulations for several markets, including plant nutrition, daily chemicals, animal nutrition, and food. The company’s main offerings are microbial-derived biostimulants, with core products like polyglutamic acid (PGA), microbial inoculants, and ε-polylysine. ε-polylysine, a key product, is a natural antimicrobial peptide produced through microbial fermentation, used as a food preservative in products like cooked rice, meats, and noodles due to its broad-spectrum activity against bacteria, yeasts, and molds. The company also develops polyglutamic acid for both agricultural and cosmetic applications. In the plant nutrition sector, Xuankai has developed the “Gu Lefeng” brand, which consists of a range of biostimulant products designed to enhance nutrient absorption and stress tolerance in crops. The company was a key participant in drafting the industry standards for cosmetic and agricultural-grade polyglutamic acid in China.
