Abstract
To provide a method for realizing complete artificial biosynthesis of starch from a simple compound.SOLUTION: Provided is a method for coupling a compound such as dihydroxyacetone, formaldehyde, formic acid and methanol by a method such as chemical reduction with carbon dioxide, and furthermore biosynthesizing starch by using carbon dioxide as a starting material. Although synthesis of natural starch requires Calvin cycle requiring the total 21 to 22 steps of reaction, this method only requires 9 to 12 steps of reaction, so that reaction steps reduces to about a half, and a production cycle can be significantly shortened. Further, high-concentration and high-density carbon dioxide and high-energy density electric energy and hydrogen energy can be utilized in this method, which is further applicable to an industrial production mode, and a production cycle can be shortened from several months to several days of agricultural cultivation.SELECTED DRAWING: Figure 1
