About SiyoMicro

Shenzhen Siyomicro Bio-Tech Co., Ltd. customizes the design and transformation of microbes to develop enzyme preparations and bioactive small molecule products. The company was co-founded by a team of PhDs from the Institute of Microbiology at the Chinese Academy of Sciences. In collaboration with the institute, SIYO Bio-Tech established a commercial genome and entity database of microorganisms from extreme environments in China.

The firm's core business focuses on developing microbial enzymes and small molecular substances from these unique environmental resources. Its products, such as Superoxide dismutase (SOD) and Ectoine, serve a wide range of industries including gene detection, in-vitro diagnosis, health products, cosmetology, medicine, food, beverage, and animal nutrition. One of the company's key products, SOD, is noted for its stability and resistance to high temperatures and acid-alkali conditions, making it suitable for cosmetic and medical applications. Another product, Natural Vanillin, is produced via a precision fermentation process.

SIYO Bio-Tech operates through subsidiaries like KiyoBio, which was established in September 2019 as a joint venture with Wuxia Jinghai Amino Acid Co., Ltd. KiyoBio runs a large-scale production facility with an annual output of over 3,000 tons of amino acids and holds certifications such as ISO9001, ISO22000, KOSHER, and HALAL. The company's business model appears to be centered on asset creation and licensing, supplying raw materials and ingredients to various sectors.
