Provided is a starch biosynthesis method. The method may implement total artificial biosynthesis from simple compounds such as dihydroxyacetone, formaldehyde, formic acid and methanol to starch, and by coupling with methods such as chemical reduction of carbon dioxide, even total artificial biosynthesis of starch taking carbon dioxide as a starting raw material can be implemented. Natural starch synthesis is required to be subjected to the Calvin cycle, needing 21-22 reaction steps in total, and the present method merely needs 9-12 reaction steps. Nearly a half of the reaction steps is reduced, and a production cycle is greatly shortened. In addition, the present method can utilize carbon dioxide having high concentration and high density and electric energy and hydrogen energy having high energy density, is more suitable for an industrial production mode, and the production cycle is shortened from several months in farming to several days. |
