Sugar is an important substance in human production and life, and it is also a key raw material for industrial bio-manufacturing today. However, it is not easy to achieve efficient and precise artificial sugar production. Recently, new progress has been made in the artificial conversion of carbon dioxide de novo precise sugar synthesis technology developed by the Tianjin Institute of Industrial Biotechnology of the Chinese Academy of Sciences. This research result realizes the artificial synthesis of hexose sugar efficiently and accurately, and provides a strong support for the use of carbon dioxide to create sugar products with diverse structures and functions.
Hexose, also known as hexose, is a monosaccharide containing 6 carbon atoms. Hexose sugars are widely distributed and abundant in nature, and are closely related to the body's nutritional metabolism. Glucose, fructose, and galactose that are common in life are all hexoses. The traditional process of carbon dioxide to biomass resources to sugar processing is limited by the energy conversion efficiency of plant photosynthesis. Under the background of global warming, extreme weather and frequent natural disasters, the production method that relies on sugar biomass resources in the past faces challenges. supply security and risk.
In order to achieve efficient and precise artificial sugar production, the Tianjin Institute of Industrial Biotechnology, Chinese Academy of Sciences has developed a de novo precise sugar synthesis technology by artificially converting carbon dioxide through a chemical-enzyme coupling artificial synthesis system. This technology is more efficient and precise than natural photosynthetic sugar synthesis, and the steps are simpler. It realizes the precise control of the synthesis of hexose sugars with different structures and functions. Its carbon conversion rate is higher than that of traditional plant photosynthesis and higher than that of chemical legal systems. The artificial sugar production method of sugar and electrochemical-biological coupling is the highest level of carbon conversion efficiency in the current artificial sugar production route.
Yang Jiangang, an associate researcher at the Tianjin Institute of Industrial Biotechnology, Chinese Academy of Sciences: We are equivalent to providing a route that does not depend on land or planting, and has constructed a synthetic route that does not exist in nature. Its route is shorter, requires less energy, and is more efficient, and it can precisely control the configuration of the product, improve the selectivity of the product, and reduce the cost of separation in the later stage.
It is understood that in the future, the scientific research team will be able to further synthesize compounds such as oligosaccharides, glycosides, or sugar alcohols through this technology, and obtain sugar molecules that are scarce or even non-existent in nature, and used as raw materials in the fields of food, medicine, and biomanufacturing .
