Homo sapiens.

Chapter 370 Please take a big black pot
2 month 22 day.

East Ying.

Kyoto University of Technology.

In a biological laboratory, Professor Shosuke Yoshida, who has long been engaged in the research of plastic-decomposing fungi, is leading several researchers to conduct experiments.

Professor Yoshida has done in-depth research in the field of plastic-decomposing fungi, and is also a frequent visitor to major biological journals. In 17, he even relied on a fungus that quickly decomposes plastics, and his papers were also published in "Science".

Since Homo sapiens decided to release the plastic-decomposing fungus, it would naturally not release it casually.

This big black pot is not something that any cat or dog can catch casually, one must find a suitable backer.

After careful screening, the Field Support Department finally set its sights on Dongying, because in this field, Dongying people have indeed done a lot of research and even obtained a lot of results.

For example, the professor Yoshida in front of me has studied a fungus that can quickly decompose plastics. He only needs to be in a humid environment of 29 degrees Celsius for about 6 weeks to decompose the predetermined plastic samples.

He also published the paper on Science.

Many Dongying people who are willing to stay now are from the group with a better family environment. They are used to living in Dongying and have no intention of leaving at all.

Professor Yoshida asked strangely: "Isn't this a normal phenomenon? Plastic-decomposing bacteria grow hyphae! What's the fuss?"

With temperature restrictions, it is the tropics that are most affected.

When he came to the laboratory, he saw that the insides of the fermentation glass tanks, the plastic bottles and the plastic bottle caps were covered with white plaques.

When Chen Jianxiong saw it, he was overjoyed.

If the temperature and humidity are not suitable for high latitudes, high altitudes, and deserts, the decomposition rate will drop several times, or even dozens of times.

In fact, the decomposition speed of plastic decomposing bacteria is not as fast as expected.

Professor Yoshida raised his glasses: "There are indeed some differences. After collecting some samples, I will conduct genetic testing."

Considering that the previous species decomposed plastic too quickly, Li Qingye inserted five specialized suppressor genes again to limit its decomposing ability.

But in the tropics, Southeast Asia is Homo sapiens, South Asia is Tianzhu, Africa is primitive people, and Latin America is just the economic colony of America.

Plastic products in these areas are impacted. In fact, the problem is not too serious. As for cables and the like, it is entirely possible to extend their service life by adding inhibitors.

Either go to Homo sapiens, or get sucked away by the Far East and America.

"Natural mutations have appeared?" Professor Yoshida showed a hint of excitement.

Assistant Xiaochi Yezi hurried in: "Professor, there is something wrong with the laboratory sample."

"Nani? What's wrong?" Professor Yoshida quickly put down the thermos in his hand.

Then he went straight to the laboratory with his assistant.

This is like a piece of paper and a book. In the same environment, the aging speed of the surface of the book is similar to that of the paper, but the aging speed of the paper inside the book is several times slower.

The diameter of these white plaques is about 1 to 3 cm, and small mycelia protrude to the surroundings, connecting with other white plaques.

……

Because many plastic products are not films and plastic bags, but rather thick tires and the like, fungi can only quickly decompose the surface layer, and the plastic inside, due to insufficient oxygen and moisture, will decompose slowly as the thickness increases. .

He looked at the screen on the computer and muttered to himself: "Is it really a mutant strain? I hope it is a good mutation."

Koike Yezi hurriedly explained: "But the mycelial morphology of those samples is different from the previous ones."

However, the plastic fungus left by them began to spread to the entire laboratory and even the entire Kyoto University of Technology and Fiber along with the air circulation system.

This situation is actually very normal and unavoidable.

The cockroaches started spitting liquid into the surrounding plastic pipes, which harbored a fungus similar to the plastic-decomposing fungus Professor Yoshida discovered.

"Hi! Professor!"

Even some Dongying people with more traditional ideas still think that those who left are a bunch of trash and traitors.

After all, only the temperature above 22 degrees Celsius will limit the reproduction. Winter in middle and high latitudes can suppress the large spread of plastic fungi.

After all, if they really research something, they might be able to gain both fame and fortune.

Inside Professor Yoshida's laboratory.

Let the plastic fungus only be in an environment above 22 degrees Celsius, the air humidity is greater than 50%, and it is easy to be killed by ultraviolet rays. Potassium permanganate and copper hydroxide can inhibit its reproduction.

At this time, dozens of cockroaches entered the air circulation duct of the laboratory.

"The decomposition speed of samples 23 to 34 has changed, and some white hyphae have grown."

Professor Yoshida, who was still immersed in research in the laboratory, did not know that a black pot was flying towards him.

Through the electron microscope, Professor Yoshida saw these "newly mutated" plastic-decomposing bacteria, and their morphology was indeed different from the bacteria he had studied before.

Those cockroaches that completed the task have disappeared without a trace.

In the environment with the most suitable conditions, its decomposition speed for ordinary polyethylene is 8 months; for natural rubber, it is 34 months; for other types of plastics, the decomposition speed is 10 to 28 months.

until a week later.

it is good!very good!You are the one!

Inside Professor Yoshida's laboratory.

From the very beginning, Li Qingye only wanted to eliminate the microplastics that spread into the natural world. There is still a limit to the plastic products that are currently being used in human society.

Including Professor Yoshida, they have a lot of family property, and Homo sapiens and America are not very attractive to them.

On this point, Li Qingye is still a little bit kind, otherwise he could have used the original variety, which is the real cruelty.

The entire laboratory became very busy because of these newly emerged mutant fungi.

The few remaining researchers are secretly thinking at this time, this time they should work harder, hoping to follow Professor Yoshida to the last "Science", and make those researchers who left regret their original choice.

At this time, the temperature in Dongying is rising rapidly. It is approaching March in Dongying, and with the blessing of the Dongying warm current, the daytime temperature in Tokyo is actually higher than 22 degrees Celsius.

This is a plastic fungus transformed by Li Qingye himself through genetic recombination technology.

And there is another advantage in choosing Japan as the first release area.

Now Japan's economy is almost in a state of collapse, many laboratory funds have been cut off, and many researchers have gone their separate ways.

That is because it is the end of winter in the northern hemisphere at this time, and the Siberian high pressure is still controlling the central and northern parts of Asia. The east ocean is blowing the northwest wind, and the east ocean current will move to the Bering Sea and North America.

Soon several researchers extracted 5 samples from several samples and started genetic testing.

It's just that they don't know. It's not sure whether it will be published in "Science" this time, but it is no problem to make international headlines.

At this time, the plastic-decomposing bacteria had spread from the Kyoto University of Technology to the entire Tokyo metropolitan area, and along with the transport ships and ocean currents, spread rapidly in all directions.

An unstoppable plastic crisis has entered the countdown.
