Sugar is an important substance in human production and life, and it is also a key raw material for industrial bio-manufacturing today. 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 in nature and in large quantities, and are closely related to the nutritional metabolism of the body. 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. In the context of global warming, extreme weather and frequent natural disasters, the production methods that rely on sugar biomass resources in the past face challenges. supply security and risk.
In order to achieve more efficient and precise artificial sugar production, the Tianjin Institute of Industrial Biotechnology of the Chinese Academy of Sciences has developed a de novo precise sugar synthesis technology by artificially converting carbon dioxide through a chemical-enzyme coupled 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 and synthesis of hexose sugars with different structures and functions. Its carbon conversion rate is higher than that of traditional plant photosynthesis, and at the same time higher than chemical legal system The artificial sugar production method of sugar and electrochemical-biological coupling is currently the highest level of carbon conversion efficiency in the artificial sugar production route.
Associate researcher Yang Jiangang from Tianjin Institute of Industrial Biotechnology, Chinese Academy of Sciences introduced that this scientific research is equivalent to providing a route that does not depend on land or planting, and it is 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 the future 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 for food, medicine and biomanufacturing and other fields.
