"It's gone, it's really gone, you boys can't bear this little hardship, leave a little for the girls. The owner of the school's small supermarket persuaded the boys who were queuing up to buy their aunt's towel, "What do you use for girls when you buy out of stock?"

There is no way, the favorable environment of the 21st century has made the post-95s and post-00s not very hard, and a military training will make everyone cry and cry their fathers and mothers.

Xiao Ming bought a bottle of water at the supermarket and did not join the ranks of buying his aunt's towel.

In the office of the principal of the administration building, Xiao Ming met Guo Mingguo, the vice principal who had made an appointment in advance.

At this time, Guo Mingguo was talking to several teachers.

When Guo Mingguo saw Xiao Ming, he immediately stood up and invited Xiao Ming to come over.

He said enthusiastically: "Xiao Ming, how do you feel, the weather is very hot these days, you should drink more water during military training, and if you feel unwell, you should tell the counselor in time." ”

The two exchanged pleasantries for a while, and Xiao Ming brought up the matter of laboratory use.

Guo Mingguo said: "At this time, I only reported to the school yesterday, the school agreed, I will give you the phone number of the logistics teacher, you need to go to the laboratory to find the teacher to get the key, but pay attention to the rules of laboratory use." ”

Xiao Ming said: "I was about to go to the biological laboratory to have a look. ”

"It just so happens that during this time, the graduate students of the Institute of Molecular Biology are doing experiments inside, so you should go with me for a while to familiarize yourself with the rules of the laboratory. If you want to use the laboratory, remember that you must do it when the laboratory or instruments are free, and follow the rules for the use of specimens, reagents, and instruments, in principle, laboratory reagents and equipment cannot be brought out. ”

"Thank you, Principal Guo, I understand. ”

Xiao Ming got the permission to use the laboratory and then wandered to the library.

The senior students have not started school, and the freshmen have long been drained of the last bit of energy in their bodies by military training, and they still have the heart to read, so there are few people in the library.

Xiao Ming didn't go to the library to borrow books, but to exchange the surprise value for books on molecular biology and genetic biology in the low-level science and technology catalog.

If you want to improve phagocytosis 1 colonies, it is definitely not enough to have only the knowledge of high school biology in your stomach.

After Yigou was introduced to the market, it brought a lot of surprise value to Xiao Ming, and at present, Xiao Ming has a surprise value of 110,003, it must be enough to exchange for a primary iron treasure chest, if you go to a low-level science and technology library to exchange books......

"Zhen Nima is expensive!" Xiao Ming couldn't help but complain.

An introductory textbook of molecular biology and experimental operation textbooks of Panfloxacin will cost a surprise value of 20,008, and a primary textbook and experimental guide of genetic biology will cost a surprise value of 40,0003.

It's really a thousand words!

Treasure chests are important, but books that allow technology to move down are even more important.

Xiao Ming gritted his teeth and exchanged a total of four textbooks and experimental books for two subjects, and the most pitiful thing was that there was no paper version, only an electronic version.

In order to get started as soon as possible, Xiao Ming found university biology textbooks in the library, such as "Biochemistry", "Modern Molecular Biology", "Cell Biology" and so on.

Bacteria all have their own enzyme systems, and different enzyme systems have different ability to decompose substrates and metabolites.

Phagocytosis 1 colony belongs to the anaerobic bacterial cluster, in which some bacteria produce enzymes that can decompose aromatic hydrocarbon macromolecular compounds in vitro, which is also the basis for phagocytosis I colony decomposition functional industrial wastewater.

If you want to improve the phagocytosis 1 colony so that it can treat domestic sewage, then it is necessary to know what the pollutants in the domestic sewage are and what are the corresponding treatment enzymes.

However, in addition to impurities, the pollutants in domestic sewage also have large amounts of organic matter, and even pathogens, which are definitely not treated by a single bacteria......

Xiao Ming has a bold idea, whether it is possible to use different bacterial colonies to comprehensively and perfectly treat the sewage like nature comprehensively transforms the environment, so that the sewage can be thoroughly recycled. And can the products of organic matter metabolized by bacteria be absorbed by nature, or can they be used by humans?

It was already five o'clock, and Xiao Ming was very focused in the library.

"Look, there's another stupid student, who just started school and held the book and gnawed again, thinking that he was going to take the graduate school entrance examination!"

"If you want to go to graduate school, you won't be prepared in your freshman year, it's too exaggerated. ”

"Biology majors? haha, there aren't many nerds anymore. ”

Some students who visited the library passed by Xiao Ming, did they laugh. After all, those who read textbooks at the beginning of school are either fools or nerds.

At eight o'clock in the evening, Xiao Ming, who was a little hungry, walked out of the library, he finished devouring a biology textbook in the university, he was very familiar with these knowledge, it seems that he had learned it in Pan Shaxing, and he read the book again to consolidate the basic knowledge, and launched a charge to more advanced scientific and technological knowledge.

Xiao Ming is also going to use the methods of high school to drink a few bottles of energy reagents to improve concentration.

After eating a light meal in the small cafeteria, Xiao Ming took a leisurely walk to the molecular biology laboratory.

To Xiao Ming's surprise, the lights in the laboratory were on, and a girl was busy in experimental clothes.

It hasn't officially started yet, and someone is in there so late?

Xiao Ming boldly walked in.

"The laboratory is not a teaching building, and new students are not welcome to visit. The girl's tone was very cold, and she didn't turn her head to look at Xiao Ming.

"I have a school charter to go into the lab. Xiao Ming was not polite, he found a set of lab coats and shoes to put on, and then disinfected his hands with disinfectant.

"You're not aseptic. ”

The girl looked at Xiao Ming, did not speak, and continued to tinker with the experiment in her hand. She had heard the leader say earlier that a freshman wanted to use the laboratory, and the school agreed, could it be this one?

"Doing gene expression regulation?" Xiao Ming said, he was observing the girls and wanted to familiarize himself with the operating rules of the laboratory as soon as possible.

"Hmm. The girl replied lightly.

In the middle of the sound, the girl said, "If you are bored, bring me that slide." ”

Xiao Ming did so, and then asked: "Eukaryotic cell DNA is combined with histones and a large number of non-histone proteins, and only a small part of the DNA is exposed, so your experiment is very difficult." ”

The girl stopped what she was doing, looked at Xiao Ming, and asked, "From the School of Life Sciences?"

The girl was wearing a mask and couldn't see it, but her eyes were bright.

Xiao Ming replied: "Professional in finance." ”

"Finance majors don't go to stock speculation and futures financial management, what the hell do you come to the biology laboratory to do, it's fun?"

Xiao Ming replied truthfully: "I'm going to cultivate some bacteria, so I know a little bit." ”

Xiao Ming's answer made the girl cry and laugh, she hugged her hands in front of her chest, and said: "I said that you are a student of finance, and you go to the biological laboratory at night to be bacteria, and it hurts to be idle?"

Xiao Ming smiled and showed his white teeth, "I can help." ”
