While Eder was using all the means for Romanian nuclear research, Foksani was also conducting another significant research experiment.

With a white coat in his hand and a loaf of bread in his mouth, Tolbov hurried to the institute, and the time on his watch was already 8:07.

"I hope the professor doesn't come, or I'll die."

Tolberf, who was twisting wildly in his heart, was running all the way, and if it wasn't for the time to accompany his girlfriend last night, he wouldn't have gotten up so late today. But no one made him see his girlfriend for almost a month, and he naturally couldn't hold it because he was young and vigorous.

But the professor doesn't listen to himself, he hates being late. If you are discovered, it is okay to be scolded, but if you get stuck in your graduation thesis, it is really uncomfortable.

It was good news that I finally arrived at the laboratory and found no professor.

"Tove, you're late today."

However, although the professor did not come, someone from the institute had already arrived.

"Overslept. Brother Neil, you won't tell the professor about it. ”

The person who came was his own senior brother, Brother Neil, who had graduated and was studying for graduate school. And Tolbow's relationship with this senior brother is not bad, so he hopes that this senior brother can cover for himself.

And the senior brother said jokingly. "Just tell me what you did last night and let you go."

Tolpuff thought about it for a moment and said it truthfully. "My girlfriend is here."

I saw Neil whistling a whistle. "Oh, yes, I'll let you go for your honesty's sake. In addition, I saw you and your girlfriend having dinner at the latest, and my eyes are really good. ”

Tolbov took out the key and asked his brother as he opened the door to the preservation room. "What is Senior Brother Neil going to take this time?"

"Take a petri dish from two months ago and do the research."

"A few."

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

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

Tolbov immediately turned around and opened a door, which was the culture room, where penicillin was cultivated at a constant temperature. And in the culture room, there are shelves in a row, and there are signs on the shelves, and soil from all continents is found here.

Because their professor Bowen found that penicillin was cultivated in different amounts in different soils. And it can reach up to 40 units per cubic centimeter, which is a remarkable improvement. Fleming, who discovered and studied penicillin, has only cultivated 2 units of penicillin per cubic centimeter. However, this is still a long way from industrialization.

It should be noted that Tolberf's job is to take care of the temperature of the incubation room and record the data. As for the study of penicillin, it is completely out of reach.

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

Tolberf, talking to himself, took one from a petri dish that had found potatoes from a row of shelves labeling New Zealand.

"Siberia...... Siberia, this way, huh. ”

When Tolbov took a Petri dish of Siberian tomatoes, he found a Petri dish in the corner of the shelf, which was unusually full of mycelium.

He couldn't help but reach out and take it. Of course, he knew about penicillin, and the penicillin in this petri dish was completely incomparable to other petri dishes.

This made Tolberf extremely happy, at least the professor could make it easy for him to graduate. Thinking of this, Tolpoff immediately took it out and walked out of the culture room with three petri dishes quickly.

Before Brother Neil could speak, Tolbouff immediately held up the unusually conspicuous petri dish and shouted at him. "Look, the penicillin in this dish is completely different from the others."

Neil had already discovered an unusually conspicuous petri dish, and he had been dealing with penicillin for many years, and his preliminary estimate was that it had at least hundreds of units of penicillin per cubic centimeter.

However, this is only his own estimate, and the specific information will need to wait for further examination to know.

However, to continue to study this cup of penicillin, at least wait for the professor himself. It's not that Neil can't study, it's a respect for the mentor who leads the team. So I saw Neil say excitedly. "I'm going to call the professor, he's going crazy."

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

"There, there's that petri dish."

Without them waiting, Professor Bolvin broke into the lab in a rage.

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

Neil held the petri dish up in a way that made Professor Boulvin a little thrilled. "Put it down, wait for me."

It was clear that Professor Bourvin was more concerned about the safety of the petri dish than Neil's offering.

Neil, who was startled by the professor's voice, quickly put it down, and his steady hand did not cause the fall to occur.

Professor Bolvin carefully held the petri dish in both hands, and walked briskly towards the test area, not forgetting to say a word to Tolbouff before leaving. "Well done Tove, give me your dissertation. I hope you will stay in the lab after graduation."

Tolbouff was ecstatic when he heard the professor's words, and the professor not only hinted that his graduation thesis would be successfully passed, but also left himself a place in the laboratory, and there was no better result than this.

Of course, it can be seen from Professor Bourwin's words that he is also very responsible for his students, otherwise how could he say what Tolburf needs.

What Bolvin needs for his students has a lot to do with the petri dish he is holding, but now it is necessary to study how much penicillin there is in this petri dish.

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

Neil, who was anxiously waiting, watched the teacher's expression cautiously until his curiosity could no longer be suppressed. "Teacher, what are the results of the examination?"

"The results were amazing, and I found that the penicillin in this dish reached 231 units, which is far more than we used to do."

In the face of his disciple's inquiry, Professor Bolvin himself couldn't help but admire this amazing result. As the leader of the project, he knows best the importance of his own research. He once visited Fleming, the inventor of penicillin, and learned a lot from the ideas he had exchanged.

As for the purification of penicillin, Professor Bolvin already has his own methods. Fleming, the inventor of penicillin, wanted to extract penicillin from the solution, but the biggest problem encountered was that penicillin was unstable, not only could not evaporate the water in the solution by heating, but could not be stored for long even at room temperature.

Professor Boulvin, on the other hand, did not heat the penicillin solution, but froze the solution into a solid state, and then sublimated the water in the frozen solution by pumping out the air and reducing the air pressure.

This may seem incredible at first glance, but it's not hard to understand. Ice cubes are placed in a closed environment at -20°C, the air is pumped out, the air pressure is reduced, and the air pressure is lower than the gas phase transition curve, and the ice will be converted into water vapor through sublimation. This method of freezing first and then removing water through sublimation is called freeze-drying, or "freeze-drying" for short.

The only thing he lacks now is the method of mass production of penicillin, which previously 40 units per square centimeter could not be applied to civilians at all, and only made penicillin a drug used by the upper echelons. This was not Professor Bourwin's wishes, although he had produced mustard gas for Romania, he had stopped working on the murderous thing in the First World War, and now he was focused on medicine. Fortunately, the research over the years has finally come to fruition.

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

He knew too well what penicillin could do, and it was a great medicine that could change the world. A host of diseases, including tuberculosis, will have a chance to be cured, and these people will have to wait for death before then. In addition, it is also effective in treating a range of conditions that cause wound inflammation.
