Synthetic starch is successful, what are the benefits?

Synthetic starch is a new starch production method, which is different from previous methods and has many advantages.

Traditional starch production is obtained through agricultural planting, and most of it depends on corn and potato extraction. In order to improve efficiency, it is necessary to improve biological varieties and expand planting area, which is a long period, complicated process and huge resource investment. The application of synthetic starch technology will change the starch production from agriculture to industrial production, which will bring two benefits:

First, the production efficiency has been improved. According to Professor Ma Yanhe, the efficiency of starch synthesis by this technology is 8.5 times that of ordinary agriculture, which is the most noteworthy point. According to estimates, the annual output of starch in a bioreactor with the size of 1 m3 is equivalent to 5 mu of corn field.

The latest data shows that China's corn planting area is about 640 million mu. If all the starch is produced by bioreactor, it only needs 65.438+0.28 billion cubic meters. If the container is calculated as 654.38+0 square x 654.38+0 meters high, it only needs 65.438+0.28 billion square meters, that is, 65.438+0.92 million mu, and the original 640 million mu can be produced.

It saves 30,000 times of land, which is only horizontal. If vertical is established, the land will be compressed again. Land use efficiency and starch production efficiency will be improved qualitatively.

Second, technology has solved environmental pain points. It is also worth noting that this technology uses greenhouse gas (CO) to synthesize starch, which can be described as "turning waste into treasure". It can not only solve the problem of greenhouse effect and realize the carbon neutrality goal set by China, but also provide technical help for interstellar navigation.

In interstellar navigation, food and water are important resources, and the carrying quantity is limited. During the voyage, CO waste gas will be discharged and oxygen will be consumed. This technical breakthrough perfectly solved these two problems, not only solved the food problem, but also consumed waste gas.

But there are many advantages. Starch can only be synthesized in the laboratory. It only takes one step to go from 0 to 1, and then it needs a transformation process from 1 to 10 and from 10 to 100. This is a process of trial and error, correction and improvement of running-in degree. This time will take several years or even decades, during which it cannot replace modern agriculture.
