SHENZHEN SIYOMICRO BIO-Tech CO.,LTD 深圳中科欣扬生物科技有限公司 was co-founded by a young doctoral team from the Institute of Microbiology, Chinese Academy of Sciences. The core members have direct/indirect experience in serving well-known/ national projects. 

SIYOMICRO focuses on the development and application of microbial enzymes and small molecular substances in extreme environment. Through cooperation with the Institute of Microbiology, Chinese Academy of Sciences, it has established the only commercial genome database and entity database of extreme environmental microorganisms in China (including plasmid, fosmid, BAC and other libraries).  The data volume of genome database exceeds 200 GB.  The data volume of entity database reaches 2KB ×10(9) .

Our mission is to become a leading global research and development enterprise of enzymes and bioactive small molecule products.  Enzymes and other biological products produced by the company are widely used in gene detection, in vitro diagnosis, health products, cosmetology, medicine, food, beverage, animal nutrition and other fields. With our outstanding innovative ability, we constantly launch a series of products and technical solutions to meet the growing demand for a better life. Our vision is to contribute a better life with biotechnology.


Core Business

Extreme Environmental Microbial

Extreme environmental microbial resources, including thermophilic, cold-loving, acidophilic, alkalophilic, halophilic, pressure-loving, gold-loving, radiation-resistant, dry-resistant and extremely anaerobic microorganisms, are rooted in China's vast territory and complex geological and climatic environment. Meanwhile, with the help of the National Ocean-Polar Science and Technology Examination Program, the microorganisms acquired by SIYOMICRO Resources are abundant, including plateau, volcano, glacier, deep sea, saline-alkali lake and so on. The commercial development of genome database of extreme environmental microorganisms, including SOD, lysozyme, tetrahydropyrimidine, lipase and biosurfactant, has been successfully completed.

Key Products



Ectoine is one of the most widely distributed osmotic compensation solutes in bacteria. It can protect the biological activity of proteins, nucleic acids, cell membranes and even whole cells under the harmful environment of high temperature, drying, freezing and radiation. Among the known compatible substances, tetrahydropyrimidine compatible solutes have the strongest protective capacity for biological macromolecules.

Superoxide dismutase (SOD)


Superoxide dismutase an active substance derived from living organisms, is regarded as the most magical enzyme in life science and technology and the garbage scavenger in human body. It converts free radicals, a harmful substance produced by organisms in the process of metabolism, into hydrogen peroxide through the above reactions. Although hydrogen peroxide is still a harmful reactive oxygen species, catalase (CAT) and peroxidase (POD) in the body immediately decompose it into completely harmless water. Thus, the three enzymes form a complete antioxidant chain.

SOD has many functions such as antioxidant aging, skin care, anti-inflammatory and so on. It has broad application prospects in the fields of daily chemical, health care, medical treatment, cosmetology and so on. However, the development of SOD is greatly limited due to the low activity of most SOD in the market, the need for refrigeration and easy inactivation. SIYOMICRO Technology Team creatively solved this problem.


The SOD developed by SIYOMICRO Technology Team is extremely stable in nature, with high temperature resistance, acid and alkali resistance and other special properties, so that SOD can be easily applied to various products, the human dream of pursuing youth, beauty and health becomes a reality.
