Chapter 378 Biological Laboratory: BSL-3 (1 more please order)
(To reiterate, this book is fantasy and science fiction, so the principles should not be scrutinized)
Chen Xiao smiled and stretched out his hand and said: "Finance major, Class of 2004, Chen Xiao."
The fat man immediately became happy, "You are Chen Xiao!!"
The students at the school definitely don’t know whether the boss behind Changtian Technology is Chen Xiao.
However, Chen Xiao has published influential papers one after another and can drive the economic development of Jiangzhou. This is obvious to all the teachers and students in the school.
Chen Xiao touched his nose, but he didn't expect that he was already a celebrity in the school.
Yang Kai was still a little surprised and said: "I heard that you have made great achievements in chemistry and computers. Now you are interested in biology?"
Chen Xiao nodded, then pointed to the broken glass on the floor and said, "Why does the room smell like alcohol? Are you doing a yeast experiment?"
Yang Kai said: "The loose wine outside the school is really unpalatable. I am studying the promotion effect of the mutual cultivation of Bacillus licheniformis and Saccharomyces cerevisiae on the flavor of strong-flavor liquor."
When talking about his experimental topic, Yang Kai seemed quite excited.
He secretly pulled out a wooden box from the corner of the laboratory and opened it.
He took out two plastic bottles from inside, handed one to Chen Xiao and said, "Do you want to try it?"
Chen Xiao quickly refused, "I'm afraid of methanol poisoning."
Yang Kai was reluctant to keep his treasure, "I am quite confident in my distillation technology."
Yang Kai asked again: "Why did you come to the laboratory..."
Chen Xiao still believes in fate.
And he believed in people's first sense.
Yang Kai gives Chen Xiao a very good feeling. He must be the kind of upright boy who can be friends with him.
Chen Xiao did not hide anything and said: "I borrowed this laboratory from your college to cultivate Rhodospirillum and cyanobacteria. Do you know anything about these two bacteria?"
Yang Kai is an absolute top biology student. He said: "Of course! Both are photosynthetic bacteria! Last year, I planned to use Rhodospirillum for sewage treatment experiments, but the instructor said no. I was so idle that it hurt.
Don’t do serious things.”
Yang Kai’s mentor is Dean Zhang, who leads Yang Kai on the topic of the impact of pathogenic microorganisms on human body functions and their pathogenic mechanisms.
Compared with such a high-level topic, the topic of sewage treatment with Rhodospirillum that Yang Kai wants to study is of course not doing his job properly.
Chen Xiao couldn't help it. He pointed at Yang Kai's pile of broken bottles and said with a smile: "Is your brewing experiment a serious matter?"
Yang Kai chuckled and was noncommittal.
The two talked a lot about cyanobacteria and Rhodospirillum.
Yang Kai believes that cyanobacteria are the great founders of life.
At the beginning of the birth of the earth, it was this huge group of organisms that continuously used limited organic matter to carry out photosynthesis crazily, creating a comfortable aerobic environment for the earth.
After a chat, Chen Xiao clearly felt that Yang Kai was indeed very good in academic attainments, otherwise he would not have been appointed as his disciple by Dean Zhang.
However, Yang Kai is obviously not doing his job properly. Whether it is environmental protection technology or brewing technology, for Dean Zhang, it is not doing his job properly.
Chen Xiao wanted to ask Yang Kai to help, but the technology he wanted to use was too confidential, and he had to rely on himself until he succeeded.
In the next few days, Chen Xiao formally applied to the school, hoping to use the school's biology laboratory alone within the next year.
The laboratory proposed by Chen Xiao is not an ordinary laboratory, but the only BSL-3 laboratory in the school.
This is the most powerful place of Jiangzhou University.
It would be great for other key universities to have BSL-2.
But Jiangzhou University was able to apply for BSL-3.
BSL-3 can conduct experiments on very infectious bacteria such as Bacillus anthracis, Yersinia pestis, Mycobacterium tuberculosis, rabies virus, etc. It is already considered a top laboratory for bacterial experiments.
The BSL-4 laboratory can study Ebola virus, Marburg virus, Lassa virus, etc. Seventeen years later, a certain virus was isolated and developed a vaccine in this standard laboratory.
After receiving Chen Xiao's application, Jiangzhou University had some doubts.
The BSL-3 laboratory is indeed relatively idle at the moment. Unless there are international-level scientific research tasks, the only role of the laboratory is to give students a tour or to let the instructors do some demonstration experiments.
Chen Xiao suddenly made this request. Of course the school would ask, what are you using it for?
See, this is the troublesome thing about not having a laboratory!
Of course, I can’t say what I’m doing specifically. Even if I say it clearly, will anyone believe it?
Chen Xiao randomly found an excuse to excuse himself - to study the service life of integrated circuits under complex biological conditions.
Although this reason is far-fetched, it still makes sense.
In addition, Changtian Technology had just attracted Nokia to invest in a mobile phone production and assembly factory in Jiangcheng, a subsidiary of Jiangzhou. After detailed discussions, the school agreed to Chen Xiao's application.
From early April to May, apart from going to the company every week to handle company matters and attending classes, Chen Xiao spent most of his time in the laboratory.
He collected multiple samples of Rhodospirillum and cyanobacteria and cultured out a certain number of populations.
Only now comes the most critical moment of the experiment.
Select the best quality from various colony samples and allow the colonies to coexist with other organisms.
This time Chen Xiao chose fruit flies - a kind of fruit fly cultivated by the Biological Laboratory of Jiangzhou University. Its body is relatively transparent but not completely transparent.
Drosophila is the best material for biological genetic laboratories because it reproduces quickly and the genes of its offspring are predictable and relatively stable.
What Chen Xiao needs to do now is to cover the bodies of fruit flies with several selected groups of Rhodospirillum bacteria so that the two can coexist symbiotically.
The purpose of symbiosis is to prove that the plan given by the system is completely correct!
Symbiosis sounds simple to say, but in fact it is quite difficult to actually practice it.
Chen Xiao wants to ensure that the metabolites of Rhodospirillum are useful to fruit flies and cannot kill them.
At the same time, it is necessary to ensure that the bacteria are not killed by the fruit fly's "immune" defense mechanism.
Chen Xiao: "This is quite nerve-wracking..."
Only through real practice did Chen Xiao understand that there is still a certain distance between theory and practice.
Even though the microbial technology tree of the technology system has informed Chen Xiao of all the experimental steps and some key experimental points, there will always be many problems when Chen Xiao puts it into practice.
After a long period of experiments and the sacrifice of dozens of offspring, coupled with the fact that the biological laboratory has relatively advanced equipment and instruments, and all raw materials are available, Chen Xiao finally completed the experiment on a fruit fly named 15-G3.
In the transparent container, 15-G3 was flying everywhere. It was not until Chen Xiao threw an apple peel down that the fruit flies clung to the apple peel and became quiet.
Chen Xiao's breathing was a little tense. He had never felt this way before when he was facing the college entrance examination.
He took 200 ml of purified water, slowly poured the water into the container, and waited for the water to completely cover the fruit skin and fruit flies.
