Five samples of Wolbachia sent from the Institute of Microbiology of Peking University were quickly delivered to Lin Han.

It was a somewhat heavy metal box, and when opened, it was tightly wrapped in several layers of blue cloth, and under the blue cloth was a layer of dry ice, which was steaming cold.

After the dry ice was cleaned, a sealed plastic box with the name Wolbachia in English written on it:

Wolbachia！

Wolbachia, is a symbiotic bacterium that mainly parasitizes various insects.

It is estimated that the number of insects infected with Wolbachia may be as high as 6 million, making it one of the most widespread symbiotic bacteria in nature.

Wolbachia has a very powerful influence on insects. The most prominent point is that it has a strong correlation with the reproduction of various insects.

For example, Wolbachia prefers females, and the next generation of infected female insects will inevitably carry Wolbachia.

In addition to this, this guy is also able to change the sex of some eggs such as bee eggs, convert males into females, and then have female bees spread their branches for it.

And some male insects infected with Wolbachia, when mating with female insects also infected with Wolbachia, will gain a powerful skill of "golden gun not falling", and the reproductive ability can even be doubled.

And these male insects, if they combine with uninfected female insects, can lead to infertility.

In short, many of the properties of Wolbachia are that it facilitates its own transmission, which allows it to quickly conquer an insect, that is, the infection rate reaches 100%......

These properties have made Wolbachia the object of research for many biologists. Biologists believe that by controlling and altering Wolbachia, a large number of insects can be indirectly affected.

A few years ago, the worst outbreak of dengue fever occurred in Dong Quang province, with tens of thousands of cumulative infections and even some deaths.

This incident attracted great attention from the Dongguang Provincial Government, and finally commissioned some scientific research institutions such as Peking University and CUHK to jointly develop new technologies to curb the reproduction of dengue virus.

The initial idea of scientists is to breed a new type of Wolbachia, which can establish a stable symbiotic relationship with mosquitoes and kill the dengue virus in mosquitoes.

As a result, with the rapid spread of Wolbachia in mosquito populations, the dengue virus will also be killed on a large scale, thus eliminating the dengue epidemic.

Professor Chen Zheyu is one of the main executors of this project......

Open the sealed plastic box, which contains five Petri dishes, as well as a copy of the written materials.

The content of the material is roughly to say, what are the characteristics of Wolbachia in these five petri dishes, what points are needed in the process of processing, and so on.

After looking at the explanatory materials, Lin Han immediately took out the five petri dishes and kept them in an incubator in his room.

Afterwards, Lin Han drove the car to the nearby sales office.

The Maybach worth three million stopped at the sales office, and as soon as Lin Han got out of the car, a tender girl in uniform and stockings greeted her, her eyes watery, and her face was hopeful: "Hello, do you need any service?"

Lin Han smiled: "I'll buy a house." ”

The girl in uniform immediately led him into the sales office, and said, "Sir, our villa here ......"

Lin Han interrupted: "If you think too much, I'll buy an ordinary small house." ”

"Huh?" the uniformed girl was stunned.

Buying a luxury car and driving it out can also represent the corporate image. But he didn't feel much about the house, and there was only one person living in it anyway......

The girl in uniform was a little disappointed: "Then which one are you going to buy, I'll pick one for you?"

"Unit 102, Building 1, Garden Complex. ”

This house is next door to Lin Han's residence.

The reason why I want to buy next door is that my original house is not enough, and after the X-ray machine and other equipment are put in, it will take up a lot of space.

In addition, X-rays are also harmful to the human body, and he can wear protective equipment, but if someone lives next door, it is likely to have a certain bad impact.

After spending hundreds of thousands of dollars to buy the house, he first asked people to make a hole in the wall to go straight to the next door, and then sealed the doors and windows of the house to make a place similar to a secret room.

Then, he arranged some necessary protective equipment and experimental equipment, and after a long period of busy work, he turned the house into a laboratory before moving in the five X-ray machines he had ordered.

......

At this time, Lin Han was wearing a white anti-radiation suit and a pair of chemical protective glasses, looking quite like a biologist.

Biological laboratories, due to the presence of biochemical pollution, are often a very well-protected type of place.

The setup of a laboratory is perfectly fine even if it is written as a book.

However, because it can control microorganisms, Lin Han's "laboratory" does not do too much biochemical protection, and the main protection work is set up for X-rays.

Out of prudence, Lin Han first made a backup of the five strains, and then divided each into ten parts, and after a certain degree of reproduction, they were placed under an X-ray machine.

The higher the frequency of electromagnetic radiation, the higher its energy and the more significant its particle.

As a high-frequency electromagnetic radiation, X-rays can have a greater impact on solid particles, which will destabilize the genetic material and increase the probability of genetic mutations.

As a result, in the dense X-ray environment, a part of the genetic material of Wolbachia has undergone structural changes, in other words, genetic mutations.

After a period of X-ray irradiation, the Wolbachia bacteria in fifty petri dishes died, mutated, and indifferent.

Turn off the X-ray machine and add the nutrient solution.

Under the influence of Lin Han, the bacteria fell into a state of excitement and quickly began to reproduce, dividing into two, two into four, and four into eight......

In the limited petri dishes, as there are more and more bacteria, the living space is becoming more and more tight.

As a result, Wolbachia has launched a fierce competition for survival in order to compete for nutrients and space......

ps：

The third more in the legend, thank you for the helmsman reward of the book friend [Lip V continues to smile]!

Folks, let's get a recommendation ticket......

Other than that:

Mosquitoes infected with Wolbachia have been used to eradicate dengue fever, and initial results have been achieved in China.

Regarding the introduction of this bacterium, there should be no problem. As for the protagonist's operation in the laboratory, I basically speculated it myself, just take a look, don't imitate it......
