• " In the chemical reaction unit, CO2 was chemically hydrogenated to methanol at a rate of ~0.25 g hour−1 g−1 catalyst, and the produced methanol was constantly condensed and fed into the enzymatic unit to a final concentration of ~100 mM during the first hour. In the enzymatic unit, the methanol was first converted to ~22.5 mM C3 intermediate DHA for another 1 hour by supplementing two core enzymes and auxiliary catalase (cat) and then transformed to ~1.6 g liter−1 amylose starch in the subsequent 2 hours by supplementing the remaining eight core enzymes and auxiliary components (Fig. 3A).
