Chapter 613 Can There Be Living Bacteria In Space?
There is a brand new metal plate hanging on the wall next to the laboratory door.
【Song He Exclusive Laboratory】
[The birthplace of the world’s first artificial vision technology, where millions of blind people have regained their sight]
Pu Songchun held the Buddhist beads in his hand with admiration in his eyes, "That's so good!"
"Damn it, if this becomes a tourist attraction and sells tickets in the future, I'll make a lot of money." Xia Wansan's money-making instinct kicked in, "Has the teacher considered auctioning off the experimental equipment used at that time?"
"Can this laboratory make biochemical weapons?" Ling Yiyi's eyes widened.
Pu Songchun frowned and glanced at Ling Yiyi, but said nothing.
Song He had a headache, "If we change it into a tourist attraction, we have to wait a hundred years before this building is abandoned. This laboratory does not meet the production standards for biological and chemical weapons. Put away all the messy ideas and focus on studying!"
Upon entering, Song He took the students one by one to identify the experimental instruments, taught them step by step how to operate them, and repeatedly emphasized the tragic accidents that may result from improper experiments.
The previous examination papers included operation questions on various experimental instruments, so the students who brought them to the laboratory had already passed the theoretical knowledge. Now they are just learning to practice, and they can teach quickly.
By ten o'clock in the morning, the students were already trying to analyze the fungi. The source of the fungi was the soil in the cactus pots on the windowsill. A scoop of soil was enough for all the students.
Song He walked back and forth in the laboratory with his hands behind his back, correcting students' incorrect operations from time to time:
"How dare you force yourself to do this? Your life is wholesale?"
"Ling Yiyi, Ling Yiyi, why don't you stick your head into the fume hood? That way of death is more painless."
"Xia Wansan, this tube of reagent costs tens of thousands, can you use it sparingly?"
"Pu Songchun, if you take down the entire laboratory with this kind of operation, all the merit you have accumulated will be wiped out in minutes!"
Song He broke out in a cold sweat. When these students came into the bright and clean laboratory, they felt like they were surrounded by murderous threats. He began to regret letting the freshmen enter the laboratory. The excitement was no less exciting than letting the color-blind people defuse bombs.
For a whole day, the careless students almost did all the prohibited operations. Fortunately, Song He corrected them in time and no tragic accident occurred.
After another full day of practice the next day, the students became more proficient in the operations, and the prohibited behaviors also plummeted. Detailed readings of various bacteria began to be analyzed. Song He was very satisfied after reading it. The top students were indeed smarter. It's stylish.
On the third night, Song He almost no longer needed to twist his neck and stare around. He could stand leisurely and browse papers on his mobile phone, and only went to provide guidance when students encountered difficulties.
In just three days, the amount of reagents used by the students has exceeded 600,000. Song He could only lament that talent is indeed the most expensive. No wonder pilots are more valuable than fighter jets. It really costs too much money to train a talent. Got it!
The phone suddenly vibrated, and there was a notification from Yuecheng Project.
[Comrade Song He, the first batch of space bacteria (outer wall of the space station) samples will arrive at the Frontier University of Science and Technology at 23:30 tonight, please bring more than five people to receive it]
There is a receive button below the notification. If you click it decisively, more notifications will be sent to you. Make sure he receives it.
Song He put away his phone, looked at the busy students in white coats in the laboratory, and clapped his hands in a clear voice.
"Everyone! Come over after what you are doing and hold an emergency meeting!"
The students hurriedly finished their work and gathered quickly, looking at the teacher eagerly, their eyes full of admiration and awe for the famous teacher.
"Remember the confidentiality agreement you signed three days ago, right?" Song He warned first, "Cherish your youth and don't leak the secret! We will pick up the goods at 11 o'clock tonight. After picking up the goods, we will work day and night!"
"Yu Caiyi, an outstanding teacher from the School of Bioengineering, will start work with his students at the same time. Our two schools will compete head-on! As long as you can win this round, the bonus will start at 50,000 yuan and the credits will start at 5 points! If you lose, you Life will be hard for you!"
The students suddenly became nervous, and the atmosphere in the entire laboratory became anxious.
"Teacher, can you tell me the specific tasks now?" Xia Wansan asked.
"The task is very simple, analyze space bacteria!" Song He said, "There are three batches of space bacteria in total, from the outer wall of our space station, from the contaminated breeding pool of the lunar base, and from space bacteria samples exchanged with certain countries. The ones coming tonight These are the first batch of bacterial samples collected from the outer shell of the space station."
The students collectively stared with wide eyes and gasped in shock!
As top academics, they knew that they would one day be exposed to such high-end space projects, but they did not expect it to be so soon!
"Teacher, are there bacteria on the outer shell of the space station?" Xia Wansan wondered, "Isn't there no life that can survive in outer space?"
"Who told you?" Song He was stunned.
"Common sense! Vacuum environment, weightless environment, cosmic rays, low temperature and no oxygen..." Xia Wansan counted with his fingers.
"Ignorant of knowledge and skills!" Song He hated the fact that iron cannot become steel, "Xia Wansan, are you just busy making money during the summer vacation? Didn't you study seriously?"
Xia Wansan blushed and hesitated.
"The dividing line between outer space and the earth's atmosphere is called the Karman line. The height is about 100 kilometers above sea level. Many microorganisms will spend their lives floating in the atmosphere at an altitude of 48 kilometers to 77 kilometers for a long time. Occasionally they will be brought to the Karman line by atmospheric movements. Other than that." Song He explained.
"This situation is similar to the toilet in your home. When you flush the toilet, a large amount of bacteria will instantly fly to the ceiling, and then float around in your home, staying there for a long time."
"Many years ago, Mao Zi discovered that microorganisms appeared on the outer shell of the International Space Station, and they were marine microorganisms. Later, the Japanese placed Deinococcus radiodurans outside the International Space Station for three years and found that the free bacteria died very cleanly, but were thicker than A lot of bacteria survived in the 0.5mm clot. Do you know why?"
Xia Wansan looked dumbfounded and hesitated to speak.
"I know!" Ling Yiyi raised her hand, "The dead bacteria form a barrier to protect the living bacteria below! As long as the thickness of the bacterial mass is greater than one millimeter, it can easily live in space for eight years. If If it becomes thicker, it is even estimated to live for about forty-five years!"
"Look, they are also provincial champions, what a big difference!" Song He looked at Pu Songchun, "Songchun, what do you know, show off to Xia Wansan!"
Pu Songchun also had a solid foundation, and he said straight away, "Lishi Huangyi can grow in low-Earth orbit, withstand water loss, vacuum, cosmic rays, temperature changes, and survive for more than a year and a half. Some very common bacteria such as E. coli and Bacillus subtilis can also survive in space for a long time after being aggregated into clumps. The most popular space fungus is thermophilic cyanobacteria, which rely on photosynthesis to survive and can survive long-term exposure to space."
"Did you remember Xia Wansan?" Song He stared at him.
Xia Wansan looked ashamed, "I made the wrong teacher, I will study hard!"
"There are still two hours. Everyone can go eat something or go back to the dormitory to take a shower." Song He looked at the time and said, "Don't be late for gathering. get out of class is over!"
