Chapter 145 Intensive Training
"Come on, take the task!" Song He slapped a pile of written large papers on the experimental table.
Immediately, a bunch of arms stretched out, each grabbing a piece of paper.
Everyone dispersed and went to work in front of their respective test benches. There was a sound of liquid flowing into glassware in the laboratory, like water gushing from a thousand springs, and the intensive work began instantly!
According to the requirements written on Song He's paper, each person only cultivated one kind of engineering bacteria, but five copies were raised at the same time with five large tanks of liquid medium, and the formula of each medium was slightly different.
Everyone can fully understand this approach. The more groups there are, the more likely the engineered bacteria will mutate.
But if you want to trigger evolution only by relying on multiple culture bottles, the probability is so small that it is negligible, and it may increase from one in 100 million to five in 100 million at most.
Therefore, the core of the experiment still relies on Song He!
Song He has a serious face, patrolling in front of rows of test benches, with sharp eyes, watching everyone's operations.
He spoke from time to time, loudly correcting:
"Lang Gaoge! The inoculation loop is burning red hot! Do you want to contaminate the culture medium?"
"Fan Tao, clean up the mess, put the pipette tip and the serological pipette back in place!"
"Du Lai, put on your mask! If mycoplasma contaminates the cells, the entire culture bottle must be thrown away!"
"The water bath was in use yesterday, right? Clean it, add some antibacterial agent, don't add double antibiotics, add 2% copper sulfate!"
"Fan Tao, go clean it! Clean the incubator with 0.1% Promethieme, and add some saturated disodium hydrogen phosphate to the water tray!"
Song He's tone was stern, like a military instructor.
The laborers who were free at first, shrouded by his invisible aura, were frightened and acted cautiously with a tense expression, for fear of being scolded.
The entire laboratory is in good order. After Song He's strict training, even the rookie high school students seem to faintly show the demeanor of laboratory veterans.
Yesterday's laboratory was full of whispering and chatting, but today it was completely silent, and the discipline was incredible.
But no one showed resentment.
A precise and strict leader gave everyone great psychological comfort and confidence.
In Song He's order, everyone felt two words - professional!
After the culture bottle was configured, Song He continued to order.
"Now, starting from bench No. 1, take a sample from each bottle and put it on the microscope! I'll look at them one by one!"
"Attention, when I'm at station 1, take samples at station 2! Station 3 doesn't move! Don't take samples too early, it will affect my judgment!"
With his hands behind his back, Song He came to Xu Tingfeng's microscope and bent over to observe.
The medicinal effect of the fungus see-through capsule kicked in, and the fungus appeared in front of my eyes.
【Bacteria No. 2 is foraging】
【Bacteria No. 2 is foraging】
[Insufficient glucose content in the environment, Bacteria No. 2 is hungry, growth retardation, and reproduction speed drops by 50%]
"Add double the amount of glucose to the first culture bottle." Song He ordered, "Record the time and dosage after adding."
"Yes!" Xu Tingfeng operated quickly, picked up the pen after adding the sugar, and quickly wrote in the experiment notebook.
Everyone needs to record the experimental process in detail for subsequent writing of papers. Science and engineering experiments, the data is too big. Especially this experiment is to find the opportunity for the evolution of engineered bacteria, so recording data is even more important.
After reading Xu Tingfeng's fungus, Song He immediately walked forward and leaned over Fan Tao's microscope.
"Miscellaneous bacteria are polluted." Song He said.
Fan Tao's face turned pale, "Then I raise another bottle?"
"Don't move for now, let them kill them! See if your bacteria can take away all the nutrients of the bacteria." Song He pondered for a moment and then shook his head, "I'll check again in the next round. If the bacteria multiply too much, then consider switching bottle."
Fan Tao nodded again and again, falling into a mood of self-blame, thinking about which link was not handled well. As a veteran of the laboratory, she shouldn't make low-level mistakes.
"Add a small amount of lactose to the second bottle, and increase the pH value of the fourth bottle to 7.2." After Song He finished speaking, he turned and left.
Fan Tao hurriedly started to work.
Song He majestically walked from one microscope to another, constantly leaning over to observe the state of the engineered bacteria.
Every time he came to a microscope, the students next to him were very nervous.
Zuo Gaoming's experiment bench was the last one. He watched the situation ahead calmly and saw a group of high school students turn pale and panicked.
"If there is anything to be nervous about, they are all classmates." Zuo Gaoming secretly smiled inwardly.
Even the helping graduate students Fan Tao and Yi Chunxiao were so nervous that they were at a loss. Before Song He approached, their backs were tense, and as soon as Song He left, their shoulders instantly relaxed.
"Graduate students are still afraid of high school students?" Zuo Gaoming was curious.
Soon, Song He walked to the fourth to last microscope.
Zuo Gaoming rubbed his hands nervously, suddenly startled, huh? Why am I getting nervous too?
I am Lu Chengen's big apprentice. I have done experiments on cultivating fungi for several years, and I am safe with my eyes closed. What is there to be nervous about?
Song He walked to the last three microscopes.
Zuo Gaoming couldn't breathe well, and he stroked his chest with his hands.
He is obviously just a high school student, and he is obviously fine with his operation, so why is he getting more and more nervous?
What's wrong with me! wake up! Nothing to be afraid of!
Song He walked to the penultimate microscope.
Zuo Gaoming panicked completely, and the tension rushed to the scalp along the blood flow. He was busy taking samples, and his hands trembled slightly.
Why am I the most nervous in the room? Don't shake your hands! I have never shaken my hands before doing experiments with Professor Lu, how could it be because of a high school student?
Suddenly, a big hand was placed on the shoulder, gentle and powerful.
"Brother Zuo, don't panic, time is not urgent." Song He's gentle voice came.
After speaking, he leaned over to look at the microscope.
In an instant, Zuo Gaoming's nervousness almost blew his head off!
He looked at the microscope! He read it! He read it!
"That's right, bottle No. 4 is placed in an incubator at 20 degrees." Song He ordered, nodded and left.
Zuo Gaoming quickly picked up the No. 4 bottle, put it into the incubator to set the temperature, and quickly wrote in the experiment notebook.
He is a person who writes beautifully, but at this moment, he writes crookedly, and his hands are still shaking!
After finishing his work, he looked at Song He's back in the distance, and the next second, he was relieved!
His hands stopped shaking immediately, his forehead was cold, and it was covered with sweat, and he felt the lingering fear of breaking through a level.
Zuo Gaoming sat down weakly, lost in thought, why am I so nervous? Why?
Is Song He's aura so strong?
Song He noticed that many people were nervous, but he didn't think much about it. He returned to the No. 1 experimental platform to conduct a new round of observation.
Although he didn't do it himself, he just commanded with his mouth, but in fact he was the one who was the most tired in the audience.
He needs to keep observing the engineered bacteria, over and over again, before he has a chance to encounter the evolutionary window period.
The morning passed quickly.
Song He did not give too radical instructions, and concentrated on cultivating and growing the colony. The conditions for evolution were harsh, and it took hundreds of thousands of bacteria to evolve one. If there were not enough bacteria in the culture medium, the evolution would be very slow.
Only a few culture bottles were overturned, and the miscellaneous bacteria hunted and killed the engineering bacteria, or the drastic change of pH value killed the engineering bacteria. The fault was not Song He, it was purely the misoperation of the subordinates who had no choice but to throw it out and raise it again.
Dozens of other culture bottles progressed rapidly, and white colonies appeared one after another, floating in the liquid like catkins.
"Song He has something, he raised so many colonies in one morning!" Du Lai sighed softly.
"Compared to our own bacteria, he is twice as fast!" Wei Huai nodded in admiration, his tone suddenly worried, "Being able to feed is a good start, but according to the data in the data book, many bacteria will die intensively in the afternoon! Just look at it." Will Song He be able to turn the tide!"
"Has it evolved? It doesn't look like it has evolved!" Su Xueduan's eyes were almost welded to the microscope.
"What's the rush, it's only been this morning! I really thought that the evolution of bacteria is about changing clothes, so you can change it if you say so? If you can mutate one in a week, it's considered super fast!" Lang Gaoge laughed.
Suddenly there was applause, and everyone looked up.
"Everyone eats in 40 minutes! Eat at staggered peak hours, half of the people go first, and the other half stay here to watch!" Song He ordered.
"Our experiment has entered a critical moment. Around three o'clock in the afternoon, there will be a wave of intensive evolution! Try to evolve three or four strains today!"
"Those who are hungry go first!" After he finished speaking, he turned to look at Xu Tingfeng who was beside him, "Bring me a chicken curry."
