The Black Technology Era of Xueba

Chapter 96 Bacteria twist into an

The two sat in the pavilion for more than an hour, and Qianyi cleaned up the garbage and left.

The one-bedroom, four-hall room belonging to Xiao Ming on the Yigou office floor has been renovated, and Qianyi has also arranged furniture and air purifiers. The room can be moved in after two or three months of ventilation.

For the past two or three months, Xiao Ming was still choosing to live on campus.

Life becomes more regular, get up in the morning for a run, go to class, and then go to the library.

Xiao Ming, who had finished his undergraduate biology textbook, attacked Pan Shaxing's biology textbook.

For the first time, he literally learned about the fungi in the phagocytosis 1 colony.

The complex name of Panshaxing could not be translated with the words here. Xiao Ming could only use letters such as A, B, and C to replace the fungi in the colony.

Here, Xiao Ming discovered the biggest difference between Panshaxing biology and contemporary biology.

The bacteria in the phagocytosis 1 colony belong to prokaryotes, but most of them have no cell wall, only a cell membrane full of folds and high strength, and the composition of the cell membrane is high molecular polymer.

In the human world, prokaryotes without cell walls are not called bacteria, but mycoplasmas, and panfloxacin is collectively called bacteria.

Oh my God!

Xiao Ming exclaimed in a low voice, most of the cell membranes of bacteria studied by humans are composed of phospholipids, while bacteria that engulf 1 colony are not. This is why these bacteria are resistant to high acid and alkali.

How does such a strong cell membrane exchange substances with the outside world?

Explanations are given later in the textbook.

For example, bacteria A, when the bacteria need to exchange substances, the highly wrinkled cell membrane will stretch out and then seal in the middle, so that the bacterial structure becomes similar to the 8, separated from top to bottom. Of course, the actual structure will be more complicated. There will be weak electrodes at the upper and lower ends of the 8, and the electrodes will attract nearby substances to gather.

The 0 above the 8 has the cytoplasm saturated with the enzyme system, and the 0 below has the genetic material DNA, which is concentrated in the low electron density region. The reason for this separation is to prevent foreign substances from damaging the DNA.

After the bacterium's structural deformation is complete, it begins to eat.

The enzyme system in the cytoplasm secretes special enzymes. The enzymes dissolve the cell membrane and let the 0 above open an opening, so that the external substances, that is, the bacteria's food, will enter the cell through the opening. Opened cell membranes are immediately closed.

After the substance enters (take aromatic hydrocarbon compounds as an example), the enzyme system will secrete the decomposition enzymes of aromatic hydrocarbon compounds, and the aromatic hydrocarbon compounds will be decomposed into methane, halogen salts, etc. after ring-opening. On contact, it also decomposes into salts, carbon dioxide and water. After the metabolism is complete, the bacteria will change from 8 to 0.

In metabolic engineering, some substances and energy will be utilized by bacteria themselves in the metabolic process.

Of course, the complex metabolic degradation process cannot be completed by one type of bacteria, and the final product of one type of bacteria's metabolism is the metabolic starting point of the next type of bacteria.

In addition, there is a type of bacteria that decomposes metabolic enzymes outside the bacteria, degrades the target in the external environment, and then absorbs the explained products into the body.

Then different substances will be degraded by different enzymes. These enzymes are the expression of bacterial DNA and part of gene expression.

There will also be one of the most difficult places in the cooperative work of bacteria. The metabolite of one bacterium will be an inhibitor of another bacterium, and the metabolite will become an operon to stop the gene expression of another bacterium or even make it die. This is a difficult problem.

There are dozens of bacteria working together in sewage treatment, so there will be more bacteria working together in urban sewage.

The experimental procedure for obtaining urban sewage treatment bacteria is clarified in the textbook.

First, the bacteria are sampled and screened. The bacterial samples here are not only the bacteria in the phagocytosis 1 colony,

There are also bacteria in urban sewage.

This time, it is to understand the gene expression of each bacteria in detail, that is, to know what kind of pollutants their enzyme systems can degrade.

Then, through various means, including gene transplantation, changing gene expression, etc., these bacteria can promote each other instead of dragging each other down, and finally form a perfect sewage treatment colony.

It is quite complicated and the amount of engineering is quite large.

It will also be applied to gene splicing and splicing technology, as well as the gene expression regulation technology that Jiangcheng University's biological laboratory is doing, but here is the gene expression regulation of prokaryotes.

I need help. Xiao Ming said: So many experiments can be completed by himself without knowing the year of the monkey and the month of the horse.

Xiao Ming thought of Molecular Biology Laboratory and Gao Siqi again.

Huh? You are also in the library? Why are you so interested in creatures?

Just when Xiao Ming was in deep thought, Gao Siqi happened to pass by, holding a few books.

You are?

Because Gao Siqi had been wearing a mask that night, and in addition to the environment in the laboratory, Xiao Ming had no idea what Gao Siqi looked like.

It wasn't until Xiao Ming saw Gao Siqi's eyes that he remembered and blurted out, Gao Siqi?

Gao Siqi sat down facing Xiao Ming and said, Shouldn't you call me Senior Sister?

Gao Siqi has long shawl hair, and her eyes are as bright as that night.

According to modern aesthetic standards, Gao Siqi is not a melon-faced beauty, but she has been dealing with biology for a long time and has a postgraduate degree. She has a temperament that many beautiful Internet celebrity girls do not have.

During the day, there are many people in the library.

Gao Siqi's impression in Xiao Ming's mind also changed from the ethereal universe, the hydrogen atoms beating in the dark, and the DNA curled up into a living person.

Forget me so soon? Gao Siqi smiled, and the smile made her more real.

No. Xiao Ming said, I just didn't expect you to come to the library.

I'm going to do a phased thesis, I just checked some information, postgraduate research monk! Gao Siqi said with a sigh.

Indeed, in terms of experimental intensity and academic professionalism, Jiangcheng University is much better than ordinary universities. After graduation, graduate students here will become cutting-edge talents in various industries, while graduate students from other schools may have poor hands-on ability than undergraduates.

The effect of operons on the expression of the enzyme system? Gao Siqi read Xiao Ming's notes on A4 paper and said, If you are interested in biology, I can tell my instructor and adjust your major.

correct!

Xiao Ming suddenly thought that Gao Siqi and her classmates were both elites in biology. With their help, wouldn't the experiment be able to be implemented quickly?

Xiao Ming's heart skipped a beat and said, Well, senior, are you free at night? I'll invite you to dinner and discuss some professional issues with you.

Okay! Gao Siqi said unceremoniously, It's good to have a sauce rabbit outside the school.
