Chapter 380 So what if it is not recognized by the West? (3 updates)
In the next few weeks, Chen Xiao tried the experiment many times, using not only Rhodospirillum but also cyanobacteria.
Both types of colonies have their own advantages and disadvantages.
Rhodospirillum can carry out photosynthesis under more severe conditions, but the metabolites it produces are partly harmful and difficult to digest and absorb by fruit flies, and the life span of fruit flies will be shortened.
The metabolites produced by cyanobacteria are relatively pure, but their photosynthetic efficiency is much lower than that of Rhodospirillum, and fruit flies may suffocate.
Genetic engineering can allow the advantages and disadvantages of both to complement each other.
In addition, light is only the necessary energy to prompt the two bacteria to produce metabolic reactions.
What Chen Xiao wants is not photosynthesis, but this metabolic reaction.
So light energy can be replaced by other energy - such as electrical energy.
Among the large number of progeny of Rhodospirillum and cyanobacteria, Chen Xiao identified those progeny with higher oxygen production efficiency and less side effects of metabolites for further experiments.
This time he needed to use genetic engineering to improve the genes of the two colonies.
The first step is to find the gene chain that produces photosynthetic enzymes in bacteria and remove it.
The second part is to implant gene fragments that are sensitive to electrical energy and can use electrical energy metabolism into the genes of these bacteria.
Chen Xiao's current microbiological level is much higher than that of the world's top scholars.
At present, there are not many studies in the microbial community on bacterial colonies that can use electrical energy for metabolism.
But Chen Xiao knows it very well.
Among them, Listeria, Clostridium (bacteria that cause gangrene), Enterococcus faecalis, etc., and even Lactobacillus, all use electrical energy in the process of metabolism. The reason why bacteria produce electrical energy is the same as how humans breathe oxygen.
Why Chen Xiao needs a BSL-3 biological laboratory is because he has to deal with these pathogenic bacteria.
Of course, Listeria does not completely rely on electrons for metabolism, but produces electrons during the metabolism process, and uses these electrons by the way.
Chen Xiao now wants to find this small gene fragment and transplant it into the bodies of Rhodospirillum and cyanobacteria.
This is very difficult!
Even if it can be made with the current equipment of Jiangzhou University's biological laboratory, it will still take a lot of Chen Xiao's time.
Chen Xiao doesn't have that much time to spend on this experiment.
He personally took the samples to the Xia Academy of Sciences in Yanjing.
Chen Xiao is not very familiar with the people in the Biology Laboratory of the Xia Guoan Academy of Sciences, but he is familiar with the people in the Physics Laboratory.
The first thing I did when I came to the Xiaguo Academy of Sciences was to find Li Dingsheng, the head of the physics laboratory.
Li Dingsheng is also considered an old friend of Chen Xiao, and he received Chen Xiao warmly.
Chen Xiao's carbon crystal memory was a major breakthrough in Xia Guo's physics community and had a profound impact on the development of the entire Xia Guo industry.
For example, in the field of physics and electronic information, researchers at the Xia Academy of Sciences can conduct in-depth research based on the technical principles of Changtian Technology, without having to follow the footsteps of Westerners.
What made Li Dingsheng most uncomfortable was that he told Chen Xiao: "At the end of last year, we used carbon crystal memory-related technology to attend a computer physics seminar in the United States. Guess what?"
Chen Xiao drank the tea brewed by Li Dingsheng and looked at the old man with a smile to vent his dissatisfaction.
"Our research results are actually not recognized by those Americans."
Li Dingsheng scolded: "Those damn guys can't do it themselves, and they still don't recognize other people's scientific research results. What kind of thing is this?!"
"I think your project is fully capable of competing for the Nobel Prize!"
Chen Xiao filled Li Dingsheng with tea and said: "In fact, the right to speak in science and technology is the right to speak in national power. Have you ever heard of a scientist from a third world country who won a Nobel-related award in his own country?"
Li Dingsheng thought for a while, and realized that this was the truth, and said: "I know this. When our atomic bomb exploded, the Americans said we were fake news and were setting off fireworks!"
Chen Xiao laughed, in fact, this kind of thing is normal.
Before the rebirth, artemisinin, which kills young children, had been used for a long time and saved thousands of people in Africa. Why was it not recognized by the West until 2015 when it won the Nobel Prize?
This is also the reason why Changtian Technology's products are not recognized by the West.
In the final analysis, it is still a matter of comprehensive national strength.
Chen Xiao said: "Scientific research is what we do. As long as our products can benefit the country and the people and help the country's scientific progress, it doesn't matter whether it is recognized by the West. These are all false. The West is a world of capital, and all recognition and
Evaluations all serve capital, not our socialism!”
The end of physics is philosophy.
Li Dingsheng lit a cigarette, took two puffs, coughed violently, and then laughed loudly and said: "You have a better life than me. We who are engaged in scientific research do not care about our reputation."
Li Dingsheng and Chen Xiao didn't meet many times, but they had a great conversation every time, and they felt like they had endless topics to talk about.
Chen Xiao looked worried at Li Dingsheng's condition and said, "Mr. Li, you should smoke less."
Li Dingsheng coughed violently again and said: "In our industry, we can't live without smoking."
"By the way, why did you come to Yanjing in person this time? Are you in trouble?"
Li Dingsheng joked: "If you can't handle technical matters, I'm afraid it will be difficult for us too."
Li Dingsheng clearly remembers that the last time Microsoft set up a trap for Changtian Technology, experts from the Computer Research Laboratory of the Xia Academy of Sciences failed to come up with a good solution for a long time, and Changtian Technology figured it out by itself.
Li Dingsheng is well aware of Chen Xiao's level.
If possible, he really hopes that Chen Xiao can make more achievements in physics instead of just in some applications.
Chen Xiao stopped being unreasonable and said: "I hope you can help me, Mr. Li. I have several groups of sample bacteria here, and I hope the genetic engineering laboratory can help me analyze the genome. I really don't have time by myself."
After saying this, Li Dingsheng was stunned.
What and what is this!
Qian was talking about physics one second, and then moved on to biology the next.
"What did you say? Bacterial sample?"
Chen Xiao nodded sheepishly, "The most advanced genetic sequencing equipment in the country is here. It's easy to get things done if you have acquaintances."
Li Dingsheng laughed and said, "You kid, you can do many things in one specialty! No problem, I will implement it for you right away. Professor Wu from the Institute of Genetics and Developmental Biology was still drinking at my house last night!"
Chen Xiao was very modest, "I don't have one specialty but many talents. I'm only half a pot of jingle."
Li Dingsheng was very efficient and immediately brought Chen Xiao and Professor Wu Wei to meet.
The office areas of the Xia National Academy of Sciences are together, but the laboratories are not.
Wu Wei's microbiology laboratory is in Yanjiao. He doesn't know what Chen Xiao is doing in testing the genes of bacteria such as Listeria monocytogenes, but he has heard about Chen Xiao for a long time and fully supports Chen Xiao's testing of bacterial genes.
Genetic engineering in Xia State started late, but it developed rapidly.
After joining the gene sequencing project in 1999, it has made great progress.
The Xia Academy of Sciences may not be able to completely test the genetic sequence of mammals, but it is relatively simple to test several groups of bacterial samples.
Professor Wu couldn't figure out what Chen Xiao was doing by testing the genes of pathogenic bacteria.
A week later, Chen Xiao got the genetic sequences of several sets of pathogenic bacteria, and he immediately started comparative analysis using his own.
