Chapter 147 Peeing In The Culture Medium?
Two fifty!
Sweat was faintly visible on Song He's forehead, and he checked the microscope more and more quickly.
Although the students in the second laboratory were only listening to orders, they were more nervous than Song He, with their hearts hanging in their throats and looking at the pillars eagerly.
Finally, Song He showed a smile, like an expedition general who found the enemy's traces after crossing mountains and mountains!
In the field of view of the microscope in front of you, a system prompt pops up!
[Half of the flora has entered the critical moment of life and death, the evolution window is open, and the countdown is 100 seconds! 】
[There are two evolutionary directions as follows:]
"Get ready!" Song He said loudly.
Fan Tao, who was next to her, was shocked, and hurriedly dragged the raw material box over, and finally checked the position of the raw material bottle. She only waited for an order, and she quickly operated it!
[Direction 1: Gluttony]
【Add trace sodium bicarbonate, lactose, thiocyanate】
[Individuals with one in 80,000 flora will increase their food intake, and their reproduction speed will increase by 20%]
Song He frowned, rose 20%, too stretched hips!
[Direction 2: Borrow another five hundred years from the sky]
[Add trace amounts of thiocyanate, salivary gland hormones, potassium chloride, and double antibodies, and incubate at a constant temperature of 10°C for ten minutes]
[One-hundred-thousandth of the flora undergoes a mutation, and the average lifespan of the mutants increases by 500%]
Song He's eyes flashed brilliantly!
Escherichia coli whose lifespan has increased by five times is definitely of great research value!
There are no ready-made purified thiocyanate and salivary gland hormones, but fortunately, these two components are present in human saliva!
Although there are other impurities in the saliva, I can't take care of so many, time is running out! Take a gamble!
"Add a little potassium chloride and double antibody, and then spit two mouthfuls of saliva!" Song He ordered.
Fan Tao heard the first half of the sentence, and hurriedly looked for the potassium chloride bottle and the double antibody bottle.
She was stunned when she heard the second half of the sentence, "Saliva?"
"Quick!" Song He urged, the evolution window is fleeting, how can we delay it?
Everyone present was dumbfounded.
Everyone watched Fan Tao, watching her add potassium chloride and double antibody to the culture medium, and quickly spit two mouthfuls of saliva into it.
She puts on lipstick, so when she spits, she deliberately opens her mouth and sticks out her tongue, letting the saliva run off the tip of the tongue to prevent the ingredients of the lipstick from falling into the culture medium, which can be described as very rigorous and thoughtful.
"Stir well! Incubate at a constant temperature of 10 degrees Celsius for ten minutes, hurry up!" Song He urged.
Fan Tao operated in a daze, adjusted the constant temperature incubator, and put the culture bottle mixed with saliva into it.
The moment the incubator was working, the 10-second countdown before Song He's eyes disappeared on the spot.
success!
The evolution window period is caught!
Song He breathed a sigh of relief, "Most of the bacteria will die after ten minutes, don't panic, keep cultivating."
"Wait until the colonies are grown, and observe the various indicators of the bacteria. Record the size, reproduction speed, lifespan, and shape of the bacteria."
"Understood..." Fan Tao couldn't help asking, "Why did you add saliva?"
"The composition of saliva is similar to that of blood plasma. There are more than 10 kinds of enzymes such as mucin and globulin, as well as minerals, organic acids and hormones. Among them, salivary gland hormones can promote cell division."
Song He briefly explained, then turned and walked to the next microscope.
He memorized all this knowledge from Fan Tao's chemistry book last night, but he didn't expect to use it today.
Everyone present was stunned.
They also studied the composition of saliva, but not as detailed as Song He.
Even if they learned as meticulously as they did, it would be difficult for them to open their minds and spit into the culture bottle!
This coquettish operation is simply unheard of, and it is even enough to be used as a negative textbook!
Song He looked at a few more microscopes, and suddenly his eyes lit up.
[More than half of the flora has entered the critical moment of life and death, the evolution window is open, and the countdown is 5 minutes! 】
[There is one evolutionary direction:]
"Get ready!" Song He said.
Du Lai, who was waiting on the sidelines, dragged the raw material box in an instant, and nervously touched a large pile of raw material bottles, like a cowboy about to draw a duel, touching the handle of a gun, so that he can shoot the gun at the first moment.
[Direction 1: Twin-Engine Fighter]
【Add trace amounts of uric acid, urea, glucose】
[One in four thousand individuals in the flora will mutate, and the mutants will grow two huge flagella from their tails, which will greatly enhance their ability to move, and their forward speed will increase by 300%]
"Uric acid, urea, and glucose! Add them all, a small amount!" Song He said quickly.
"Only urea and glucose..." Du Lai was stunned.
"We don't have diabetics here?" Song He raised his head and asked.
Everyone was stunned and shocked, shaking their heads dully. The students have been completely dumbfounded by Song He's operation show.
"Brother Du Lai, go to the toilet and pee at the bottom of a test tube, and add some glucose." Song He smiled.
"Do you add urine directly to the culture medium?" Du Lai was shocked.
"That's right, boy pee." Song He joked.
Du Lai had a dreamy expression, full of disbelief, but he still ran to the bathroom.
After a while, Du Lai hurried back and added a few drops of urine and glucose into the culture bottle.
"Teacher Song... what kind of operation is this wave?" Du Lai asked with difficulty, and his three views were shaken.
"Escherichia coli eats urea and can decompose urea into ammonia. Uric acid is a stimulus, and glucose replenishes energy." Song He explained casually, "A lot of Escherichia coli will die in the future, cultivate slowly and pay attention to observation."
Du Lai stood where he was, looking at the culture bottle filled with urine, lost in thought.
Finally, Song He came to the last microscope, took a look at it, and said "ready!"
Zuo Gaoming waited for a long time, and asked weakly, "Do you want tears or sweat?"
"Neither." Song He leaned over and stared at the microscope.
Zuo Gaoming's face changed suddenly, and he guessed cautiously, "Arginine?"
"What are you thinking?" Song He looked up and gave him a suspicious look.
Zuo Gaoming looked embarrassed, digging his toes.
"Potassium chloride, lactose, and citric acid." Song He quickly ordered, "After adding them, keep them in an incubator at 37 degrees Celsius for half an hour."
Zuo Gaoming got busy, and secretly heaved a sigh of relief. Fortunately, the evolution materials needed for his bacteria are not evil, and it sounds quite normal. The two evolutionaries in front were drooling and urinating, which frightened him.
After watching a lap, Song He's tense nerves relaxed a lot.
He plans to improve three or four types of engineered bacteria today, and the circle has already been assembled, and the window period has been seized, and the task has been completed.
For the three types of bacteria that have started evolution, the mutation direction is Fan Tao's "borrowing another five hundred years from the sky", and the life span of the bacteria group will increase by five times. In Du Lai's "Double-Engine Fighter", two strong flagella will grow from the buttocks of the bacteria colony, like two long legs. And finally Zuo Gaoming's "expansion", the bacteria will double in size.
Du Lai and Zuo Gaoming's bacteria are more tasteless after mutation.
Fantao's fungus is extremely valuable for research! It is no less than No. 1 bacteria, which swelled four times yesterday!
Song He thought of the engineering bacteria contract given by Zhuang Xia. He felt that he would sign more than one contract. After these engineering bacteria were improved, would he become rich overnight?
"Don't relax! Continue!" Song He started a new round of microscope inspection.
The students became nervous. There are already three kinds of bacteria that have started the evolution process. Will your own bacteria be far behind?
Some students also looked suspicious, why does Song He's evolution formula sound so unreliable? Can it work?
time flies.
At ten past three, the door of the first laboratory suddenly opened, and Lu Chengen hurried over.
At the same time, the door of the second laboratory opened almost at the same time, and Dean Lou appeared in a white coat, and ran towards Song He with a clear goal.
The eyes of the two leaders were beating with anticipation!
