Chinese scholar Science published breakthrough results: original research on artificial starch synthesis

Recently, Ma Yanhe's team from Tianjin Institute of Industrial Biotechnology, Chinese Academy of Sciences has made breakthrough progress in the artificial synthesis of starch, and achieved the de novo synthesis of carbon dioxide into starch for the first time in the world

On September 23, the Chinese Academy of Sciences held a press conference to interpret the results and progress

At present, starch is mainly produced by corn and other crops through natural photosynthesis to fix carbon dioxide.

In this research, the Tianjin Institute of Technology designed a new way of unnatural carbon dioxide fixation and artificial starch synthesis with 11 main reactions from scratch, realizing the total synthesis from carbon dioxide to starch molecules for the first time in the laboratory

This research has innovated the biological process technology of high-density energy and high-concentration carbon dioxide utilization by coupling the chemical catalysis and biocatalysis module system.

Related achievements make it possible to transform the traditional agricultural planting mode of starch production to the production mode of industrial workshop, and provide a new technical route for the synthesis of complex molecules from carbon dioxide raw materials

The results have been highly praised by experts in related fields at home and abroad, and they are considered to be "typical 0 to 1 original breakthroughs", "a major breakthrough in the frontier research field of expanding and enhancing the ability of artificial photosynthesis, and a significant "indomitable" significance.

This research has received funding and support from the key deployment projects of the Chinese Academy of Sciences and the Tianjin Synthetic Biotechnology Innovation Capability Improvement Initiative.

Since 2015, Tianjin Institute of Technology has focused on the bio-transformation and utilization of synthetic starch and carbon dioxide, carried out demand-oriented scientific and technological research, gathered innovative resources inside and outside the institute, strengthened the integration of "discipline-task-platform", and realized the organic integration of scientific research forces of all parties.
