Chinese scientists have become the first in the world to develop a method for synthesizing starch from artificial carbon dioxide (CO2).The study, published online in the journal Science on Friday. It is operated by the Tianjin Institute of Industrial Biotechnology of the Chinese Academy of Sciences.Starch, a form of carbohydrate retention It is the main component of grain and important industrial raw materials.
It is currently mainly produced by crops such as corn and rice by
slot fixing CO2 through photosynthesis. The process involves about 60 biochemical reactions and complex physiological controls. with a theoretical energy conversion efficiency of only 2 percent.This new method has made it possible to shift starch production from traditional agricultural cultivation to industrial production. and opens up new technical routes for the synthesis of complex molecules from CO2, said Ma Yanhe, corresponding author of the report.
The talc anabolic pathway (ASAP), comprising 11 core reactions, was outlined by a computerized pathway design, which was generated through modular assembly and substitution and optimized by protein engineering of three bottleneck-associated enzymes. " the author writes In a spatial and temporal separation chemistry, the hydrogen-powered ASAP converts CO2 into starch at a rate of 22 nm CO2 per minute per milligram of the total catalyst.
which is 8.5 times higher than the rate of starch synthesis in corn,” they explained in detail.
The study's lead author, Cai Tao, said that the starch samples synthesized in this new method were not synthesized. "It's like a naturally produced starch in terms of its composition and physical and chemical properties.In theory, if given enough energy according to the current technical parameters Yearly production of starch in a bioreactor of 1 cubic meter per year. It is equal to the annual yield of flour from one third of a hectare of corn.
If the overall cost of the system can be reduced to economic levels comparable to future agricultural crops. It is expected to save more than 90 percent of arable land and fresh water, according to the researchers.It also avoids the negative effects of pesticide and fertilizer use on the environment and alleviates food shortages.
