Today, everyone must have been brushed by a message, I said that for the first time to achieve the synthesis from carbon monoxide to protein, for friends who do not understand, must be confused, do not know what this thing means, how significant the meaning is!
<h1 class="pgc-h-arrow-right" data-track="4" > protein synthesis</h1>
Protein is the most important component of all cells and tissues for humans, and all important components of our body need to have the participation of proteins, which alone account for 16 to 20% of the body's body weight. Protein can be said to be the material basis of life, and we can say that without protein, there is no life.
Protein synthesis is actually the process of transcribed an organism's DNA into mRNA. This is a very complex process, if we want to make proteins naturally synthesized, this process usually in the plant body or in the plant body has nitrogen-fixing function of specific microorganisms to do it, they will photosynthesis to form carbohydrate sugars, and then through the tricarboxylic acid cycle through a number of complex biological conversion and enzymatic reactions, the formation of protein components - amino acids, thereby further synthesis of proteins.
Photosynthesis requires sunlight, water and carbon dioxide, and the utilization rate of sunlight is only 3%-6%.
In this process, it involves the very complex genetic expression of organisms, biochemical synthesis and other life processes, the synthesis of natural proteins
It is a very inefficient process, and in the original protein synthesis process, the conversion efficiency of matter and energy is very low.
<h1 class="pgc-h-arrow-right" data-track="10" > carbon monoxide synthesizes proteins</h1>
The synthesis of protein is inseparable from nitrogen, so for plants with sufficient nitrogen, the proportion of protein synthesis is also relatively high. According to Dr. Xue Min, chief scientist of the project and researcher of the Feed Institute of the Chinese Academy of Agricultural Sciences, under artificial conditions, we can biosynthesize proteins on a large scale with carbon monoxide and nitrogen sources, which has broken through the core key technology of Clostridium ethanol protein, greatly improved the reaction speed (22 seconds synthesis), created a world record of the highest biosynthetic protein yield of 85% under industrial conditions, and formed a 10,000-ton industrial production capacity.
That is to say, under the condition of synthetic synthesis, the speed of natural synthesis is increased by dozens of times. Breaking through the boundaries of time and space, protein synthesis is realized in an industrial way.
<h1 class="pgc-h-arrow-right" data-track="13" > Clostridium ethanol protein</h1>
Clostridium ethanol protein is a new type of single-cell protein obtained by using Clostridium ethanol in the intestines of rabbits as a fermentation strain, and then using carbon monoxide, carbon dioxide exhaust gas and ammonia as the original, liquid fermentation culture, centrifugation and drying. The structure of this protein is simple, mainly based on proteins, peptidoglycans, trace elements and a small amount of metabolite acetic acid. That is to say, we synthesize proteins from exhaust gas and ammonia, and achieve a zero-to-one process, which is very remarkable.
At present, the application of Clostridium ethanol protein is consistent with the classification of categories and yeast proteins commonly used in the feed industry. The raw material production efficiency of Clostridium ethanol protein is 700,000 times that of traditional methods, and it has high nutritional value, high protein content, and can also be used to improve feed quality. In the study, the effectiveness and safety of this protein have been verified, not only that, they also have many excellent properties, is a very high-quality source of feed protein.
<h1 class="pgc-h-arrow-right" data-track="16" > the significance of industrial protein production</h1>
By converting inorganic nitrogen and carbon into organic carbon and nitrogen, in order to create a new type of feed protein resource Clostridium ethanol protein, this shows that we no longer have to compete with people for food, nor do we have to compete with food for land, which is of great significance for us to ensure national food security and achieve green and sustainable development.
It should be known that China is the world's largest country in feed production and consumption, the number of soybeans imported from abroad every year is very large, but the dependence of feed protein raw materials on foreign countries is 80%, and the research and development of Clostridium ethanol protein breaks through the time and space limitations of natural protein plant synthesis, opening up a subversive non-traditional new way and industrialization path for the production of high-quality feed protein, and directly solves the problem of China's soybean protein feed card neck.
According to expert estimates, the industrial production of 10 million tons of Clostridium ethanol protein is equivalent to importing 28 million tons of soybean equivalents, reducing carbon dioxide emissions by 250 million tons.
This research is really good for the country and the people! Kudos to all the great scientists!
