Chapter 679： penicillin

While Edel used all the means for Romania's nuclear research, Focşani was also doing another significant research experiment.

Tolbov hurried to the institute with a white coat in his hand and a bread in his mouth. The time on his watch had reached 8:07.

"I hope the professor does not come, otherwise I will die."

Torbov, who was twisting in his heart, ran all the way. If he hadn't been for his girlfriend last night, he wouldn't have gotten up so late today. However, he hasn't seen his girlfriend for almost a month, so young and vigorous naturally can't hold it.

But the professor doesn't listen to himself. He hates being late. It would be nice to be scolded if discovered, but it would be really uncomfortable to get stuck in your graduation thesis.

Hurry up and finally came to the laboratory, and did not find the professor. This is really good news.

"Toff, you are late today."

Although the professor did not come, someone from the institute has already come.

"Overslept. Brother Neil, you won't talk to the professor."

The person here is his brother, brother Neil who has graduated and is studying for graduate school. Tolboff had a good relationship with this senior, so he hoped that this would provide cover for the senior.

And the brother said jokingly. "You just have to say what you did last night and let you go."

Tolbov thought for a while or told the truth. "My girlfriend is here."

Neal was urged to blow a whistle. "Oh, yes, I will let you go for the sake of your honesty. In addition, I saw you and your girlfriend having dinner at the latest, so I have a good vision."

Tolbov took out the key and asked his brother while opening the door of the storage room. "Brother Neil, what are you going to get this time."

"Take a petri dish two months ago for research."

"How many."

"Give me a New Zealand potato and a Siberian tomato."

"Please wait a moment, I'll bring it to you tomorrow night."

Tolboff immediately turned around and opened a door. This is the cultivation room, where penicillin is cultivated at a constant temperature. Moreover, there are rows of shelves in the cultivation room, with signs standing on the shelves, and soils from all continents are found here.

Because their professor Bolvin found that the amount of penicillin cultured in different soils is different. And its maximum can reach 40 units per cubic centimeter, which is a remarkable improvement. Fleming, who has discovered and studied penicillin, has only cultivated 2 units per cubic centimeter of penicillin. However, this is still a long way from industrialization.

This needs to be explained. Tolbov’s job is to be responsible for the temperature of the cultivation room and record the data. As for the study of penicillin, I can't get involved at all.

"New Zealand is here, potatoes...potatoes, here."

Tolbov, who was talking to himself, took one of the petri dishes where the potatoes were found on the shelves marked New Zealand.

"Siberia...Siberia, here, hey."

After Tolbov took away a Petri dish of Siberian tomatoes, he found that there was a Petri dish in the corner of the shelf, and the hyphae in it appeared unusually large.

This made him reach out and take it over. He certainly knows penicillin, the penicillin in this culture dish is not comparable to other culture dishes.

This makes Tolbov extremely happy, at least the professor can let him finish his course smoothly. Thinking of this, Tolbov immediately took it out and walked out of the incubation room with three petri dishes.

Before Brother Neil could speak, Tolbov immediately raised this unusually conspicuous petri dish and shouted to the brother. "Look, the penicillin in this petri dish is completely different from other petri dishes."

Neal has long discovered an unusually conspicuous petri dish. After dealing with penicillin for many years, he initially estimated that it was at least hundreds of units per cubic centimeter of penicillin.

But this is only his own estimation, and the specific information needs to be further tested before he knows it.

But to continue to study this cup of penicillin, at least you need to wait for the professor himself. It's not that Neil couldn't study it, but the respect for the team leader. So I saw Neil talking excitedly. "I'll call the professor, he must be crazy."

After finishing talking, Neil thought of something and continued talking to Tolbov. "You prepare the operation records of the past few months, I believe you will be able to use them in a while."

"There, the petri dish is there."

Without asking them to wait any longer, Professor Bolvin rushed into the laboratory.

"Here, professor, do you see if there is more penicillin in all our petri dishes before, and it is still several times higher."

Neil raised the petri dish in a manner of offering treasures, which made Professor Bolvin a bit thrilling. "Hurry down and wait for me to come."

Obviously, Professor Balvin is more concerned about the safety of this petri dish than Neal’s offering.

Neil, who was startled by the professor's voice, put him down quickly, and there was a time when his steady hands did not cause the fall.

Professor Bolvin carefully held the petri dish in both hands, walked quickly to the test area, and did not forget to say something to Tolboff before leaving. "Good job Tove, give me your graduation thesis. I hope you can continue to stay in the laboratory after graduation,"

Tolbov was overjoyed when he heard the professor's words. The professor not only hinted that his graduation thesis would pass smoothly, but also gave himself a place in the laboratory. There was no better result than this.

Of course, it can be seen from the words of Professor Bolvin that he is also very responsible to the students, otherwise how can he tell what Tolbov needs.

What Bolvin needs for the students, of course, has a lot to do with the petri dish he is holding, but now we first need to study how much penicillin there is in this petri dish.

saw him carefully put the petri dish under the microscope, silently observing and recording.

And Neil, who was waiting anxiously, watched the teacher's expression cautiously, until his curiosity couldn't help it anymore. "Teacher, how was the result of the inspection?"

"The results are amazing. I found that the penicillin in this petri dish reached 231 units, which is far more than what we had before."

Facing the question of his disciple, Professor Bolvin himself couldn't help but admire the amazing result. As the person in charge of the project, he knows the importance of his research best. He once visited Fleming, the inventor of penicillin, and he benefited a lot from many points of view during his exchanges.

As for the purification of penicillin, Professor Bolvin already has his own way. Fleming, the inventor of penicillin before, wanted to extract penicillin from the solution. The biggest problem encountered was that penicillin was unstable Not only couldn't the water in the solution be evaporated by heating, but it was also stored at room temperature. It won’t be long.

Professor Bolvin did the opposite. Instead of heating the penicillin solution, he freezes the solution into a solid state, and then sublimates the water in the frozen solution by evacuating the air and lowering the air pressure.

This approach may seem incredible at first glance, but it is not difficult to understand. Place ice cubes in a closed environment at -20°C, evacuate the air and lower the air pressure until the air pressure is lower than the gas phase curve, the ice will be converted into water vapor through sublimation and escape. This method of freezing first and then removing water by sublimation is called freeze drying, or "freeze drying" for short.

The only thing he lacks now is the method of mass production of penicillin. Previously, 40 units per square centimeter could not act on civilians at all, and it would only make penicillin a medicine used by the upper level. This was not the wish of Professor Bolvin. Although he used to produce mustard gas for Romania, he stopped studying the murderous thing in World War I. Now he is devoted to medicine. Fortunately, these years of research finally yielded results.

Professor Bolvin looked at this penicillin with joy in his eyes. I have several ideas in my mind, and use this as a way to further cultivate the mother plant penicillin.

He knows the effect of penicillin too well, it is a great medicine that can change the world. A large number of diseases, including tuberculosis, will have a chance to be cured, and these people can only wait to die here. In addition, it is also effective in treating a series of symptoms of wound inflammation.
