I Exchange For Black Technology By Blowing Up The Bully

Chapter 746 The Progress Of Ling Bacteria

The laboratory at the end of the corridor.

When Song He walked in, it was like entering a sand museum.

Rows and rows of specimen jars filled the entire room, and the walls were covered with iron racks. There were hundreds of jars of yellow sand on one wall, and there were also sand jars on the table, in the cabinets, and in the corners.

Some of the sand jars have golden lights near them, making them shine like gold. Some sand jars have white lights near them, giving them a texture like bone meal.

A dozen people in white coats are busy, led by Ling Yiyi, Pu Songchun and Xia Wansan. After being immersed in the laboratory for a long time, the young people have the temperament of old experimenters in their movements, and their posture is particularly professional.

"How is Ling Jun?" Song He asked.

The three top picks looked up and realized that the teacher had come in. They quickly stopped what they were doing and came over to report.

Ling Yiyi brought over a piece of data paper and said, "Teacher, the best fungus sample so far is this one."

Song He took the data sheet and noticed the number in the upper right corner:

[Lingjia subspecies 1607]

"It's pretty fast. We've already made 1,600 subspecies." Song He was slightly surprised.

"Actually, we have made more than 4,000, but unfortunately the performance of the next 2,000 or so has gotten worse and worse." Xia Wansan said next to him, and sighed after speaking.

"Have you summarized the reasons?" Song He asked.

The three top picks shook their heads together. Looking at their expressions, the shaking of their heads did not mean that they had not done their homework, but that the questions were too difficult and they could not write.

"The best subspecies, 1607, is a jar that Pu Songchun raised casually, without much skill." Ling Yiyi was embarrassed, "We worked hard to genetically modify or induce subspecies, and spent a lot of experimental funds, but the results were not as good as This jar was grown casually.”

Song He laughed, it's hard to evaluate.

Let’s just say the students are not good at cooking. The variety they put so much effort into making is a mess.

Let's talk about their talents, and they can get good luck by chance.

Fortunately, scientific research is based on results. No matter how outrageous the process is, as long as the results are produced, we can make a difference.

Many great scientific research achievements in history were just a blind attempt. A typical example is graphene. It took a long time for colleagues to work on it with various expensive instruments. In the end, Heim used scotch tape to stick it on, and he was surprised to find that it actually sticks. Graphene with a carbon atom thickness was produced, and six years later it was on the Nobel Prize podium. Later, many scholars crashed on the Internet and asked for help. What brand of tape should be used to have a higher success rate?

Song He looked at the data sheet carefully and found that the effect of subspecies 1607's sand to soil conversion was quite good! It is very close to the sand-to-soil technology already on the market!

It can even be said that, similar to the difference between Pepsi-Cola and Coca-Cola, people who are not sensitive to taste cannot tell the difference at all!

Song He was about to return the data paper when Pu Songchun raised the prayer beads in his hand and said, "Teacher, there is still a back side."

Turning it over, there was indeed something on the back. Song He suddenly noticed that the fonts and charts on the data paper were printed in a smaller size, and couldn't help but laugh, "Are you saving paper?"

"It's too expensive to spend money. I want to help the teacher save some money as much as possible." Xia Wansan nodded.

"Stupid! Xia Wansan, you are also a business-minded person. This kind of saving is useless." Song He shook his head, "I earn a lot of money from overseas. If the exchange rate changes slightly, I may gain tens of millions or lose thousands in an instant. Ten thousand, enough to buy a trainload of paper for you to use from the Ming Dynasty to now!"

The three top picks blinked, a little at a loss.

"I don't mean to criticize you. I mean well, but I'm too naive. The scientific research funds allocated to you can be used freely. If you can use disposable things, use disposable ones to save time." Song He said, looking at Look at the back of the data sheet, "Fertilizer?"

"Yes, we are trying to give Lingbacteria the ability to fix nitrogen in the air, so that we can add some nitrogen fertilizer to the soil." Xia Wansan said, "But the progress is difficult now."

"What's the specific difficulty?" Song He asked.

"Mutations also have content." Xia Wansan said, "Each generation of Lingbacteria subspecies will mutate from time to time, and we can't control the direction. Some will suddenly lose their ability to fix nitrogen in the air, while others will have a sudden increase in their ability to fix nitrogen."

"The sudden increase in nitrogen-fixing ability has two side effects." Ling Yiyi took over, "One side effect is the imbalance in Ling Bacteria's body, causing Ling Bacteria's death, just like overeating and starving oneself to death. The other side effect is the nitrogen content of the soil changed from sand The surge will increase to a level that is unbearable for the plants, and will eventually lead to the death of crops in large numbers!”

"Bring me the detailed version of the data. This abbreviated version is useless," Song He said.

The three top picks immediately dispersed and rummaged around in the file cabinet in the corner, like thieves breaking into a house. They quickly found dozens of thick data papers, each as big as a test paper, and handed them to the teacher.

Song He flipped through it quickly and nodded slightly, "Obviously, it's a nitrogenase problem!"

The three top picks hurriedly took out their pens and papers and listened to the teacher's instructions.

"Nitrogenase is composed of two proteins, ferritin containing iron, and molybdenum ferritin containing iron and molybdenum. These two are electron carriers. Nitrogenase only works sometimes at the same time. It doesn't matter if one of them is missing."

"And both ferritin and molybdenum ferritin are particularly sensitive to oxygen. They are inactivated when exposed to oxygen and are irreversible. I remember that the deactivation speed of ferritin is half of it in 45 seconds, and that of molybdenum ferritin is half of it in ten minutes. If you are not careful, it will It’s over.”

Song He turned around to look for something. Xia Wansan was very discerning and immediately pulled a chair from the side.

"Thank you." Song He sat down, "The problem you mentioned is actually easy to solve. There is a new technology called mutation lock. I came up with it when I was doing artificial white blood cells some time ago. I can teach you. Mutation lock is very useful. It's simple, just focus on key genes, such as the nitrogen-fixing gene, to prevent them from mutating."

The three top picks were stunned for a moment, with shocked expressions on their faces.

Prevent key gene mutations?

As biological people who are new to the world, they can imagine how explosive this technology is!

"Ling Yiyi just talked about two side effects." Song He said, "Actually, the solution lies in these two side effects! Use side effects to solve side effects."

The top picks blinked cutely and used side effects to solve side effects?

"Different subspecies of Lingbacteria have limited tolerance to the nitrogen content in the environment. You can set a soil nitrogen fertilizer value and create new subspecies based on this value. Once the nitrogen fertilizer value is reached, the subspecies will die in batches, reducing the number of subspecies. Nitrogen fixation.”

"I have given you a similar idea before. You can macro-control the types of bacteria by controlling the pH value. Have you forgotten?" Song He asked.

"We have thought about this, but it is difficult. The difficulty lies in mutation." Xia Wansan scratched his head.

"So you have to learn the mutation lock. If you learn the mutation lock well, everything will be solved." Song He nodded, thought for a moment and then said seriously, "I think the laboratory stage of the Lingji project is over. You have gone into a misunderstanding."

"The laboratory stage is over? Then... what is the next stage?" Ling Yiyi was confused.
