While Edel was using all means for Romania's nuclear research, another significant research experiment was also being conducted far away in Foksanyi.
Tolbov hurried to the research institute with a white coat in his hand and a piece of bread in his mouth. The time on his watch had already reached 8:07.
"I hope the professor didn't come, otherwise I would be dead."
Torbov was running wildly in his heart. If he hadn't been with his girlfriend last night, he wouldn't have gotten up so late today. But he hadn't seen his girlfriend in almost a month, and he looked so young.
Sheng naturally couldn't control it.
But the professor wouldn't listen to me. He hated people being late. If he was discovered, he would be scolded, which would be fine, but it would be really uncomfortable if he got stuck on his graduation thesis.
I hurriedly and slowly finally arrived at the laboratory, but no trace of the professor was found. This is really good news.
"Toff, you're late today."
However, although the professor did not come, someone from the institute has already come.
"I overslept. Brother Neil, you won't tell the professor about it, right?"
The person who came was his senior brother, Neil, who had graduated and was studying for a postgraduate degree. Tolbov had a good relationship with this senior brother, so he hoped that this senior brother could cover for him.
And this senior brother said jokingly, "As long as you tell me what you did last night, I'll let you go."
Tolbov thought for a while and told the truth. "My girlfriend is here."
I saw Neil blowing a whistle. "Oh, that's right. For the sake of your honesty, I'll let you go. Also, I saw you having dinner with your girlfriend at last. You have really good taste."
Tolbov took out the key and asked his senior brother while opening the door of the storage room. "What does Senior Brother Neal want to get this time?"
"Take the petri dishes from two months ago and do research."
"How many."
"Give me a New Zealand potato and a Siberian tomato."
"Please wait a moment and I'll bring it to you tomorrow night."
Tolbov immediately turned around and opened a door. This is the culture room, where penicillin is cultured at a constant temperature. There are rows of shelves in the culture room, and there are signs on the shelves. Soil from all continents is available here.
Because their professor Bolwin's research found that the amount of penicillin cultured in different soils is different. The highest it can reach is 40 units per cubic centimeter, which is a great progress. Fleming, who currently discovered and studied penicillin, also cultivated it.
2 units of penicillin per cubic centimeter. However, this is still far from industrialization.
This needs to be explained. Tolbov's job is to be responsible for the temperature of the culture room and recording data. As for the research on penicillin, he has no involvement at all.
"New Zealand is here, potatoes... potatoes, here."
Talking to himself, Tolbov found a potato petri dish on a row of shelves labeled New Zealand and took one.
"Siberia...Siberia, this way, eh."
After Tolbov took away a Siberian tomato petri dish, he found a petri dish in the corner of the shelf with an unusually large number of mycelium.
This made him couldn't help but reach out and take it over. Of course he knew about penicillin. The penicillin in this culture dish was completely unmatched by other culture dishes.
This made Tolbov extremely happy, at least the professor could allow him to graduate smoothly. Thinking of this, Tolbov immediately took it out and walked out of the culture room quickly with three petri dishes.
Before Brother Neal could speak, Tolbov immediately held up this unusually conspicuous petri dish and shouted to him. "Look, the penicillin in this petri dish is completely different from other petri dishes."
Neil had long discovered an unusually conspicuous petri dish. Having worked with penicillin for many years, he initially estimated that it contained at least hundreds of units of penicillin per cubic centimeter.
However, this is just his own estimate, and the specific information will not be known until further testing.
However, if we continue to study this cup of penicillin, we must at least wait for the professor to do it in person. This is not because Neil cannot study it, but because he respects his mentor. So Neil said excitedly, "I'll call the professor right now.
, he must be crazy with joy.”
After finishing speaking, Neil thought of something and continued to say to Tolbov. "Prepare the operation records of the past few months. I believe you will be able to use them later."
"There, that petri dish is there."
Without letting them wait any longer, Professor Bolwin burst into the laboratory in a hurry.
"Professor, can you see if there is more penicillin here than in all the petri dishes we had before? The difference is still several times greater."
Neil lifted the petri dish like a treasure, which made Professor Bolvin a little frightened. "Put it down quickly and wait for me."
It was obvious that Professor Bolvin was more concerned about the safety of this petri dish than Neil's treasure offering.
Neil, who was startled by the professor's voice, quickly put it down, and his hands were steady enough not to cause it to fall.
Professor Bolwin carefully held the petri dish with both hands and walked quickly to the experimental area. Before leaving, he did not forget to say something to Tolbov. "Well done, Tov, what do you want to give your graduation thesis to?"
I.I hope you can continue to stay in the laboratory after graduation,"
Tolbov was overjoyed when he heard what the professor said. The professor not only hinted that his graduation thesis would be passed smoothly, but also left him a place in the laboratory. There is no better result than this.
Of course, it can be seen from Professor Bolvin's words that he is also very responsible for his students, otherwise how could he tell what Tolbov needs in one sentence.
Of course, what Bolwin gave the students needed had a lot to do with the petri dish he held in his hand, but now we first need to study how much penicillin there is in the petri dish.
I saw him carefully placing the petri dish under the microscope, observing and recording it silently.
Neil, who was waiting anxiously on the side, carefully looked at the teacher's expression until his curiosity could no longer be suppressed. "Teacher, what are the results of the examination?"
"The results were surprising. I found that the penicillin in this petri dish reached 231 units, which was far more than what we had before."
Facing the inquiry from his disciple, Professor Bolvin himself couldn't help but admire this amazing result. As the person in charge of the project, he knew the importance of his research best. He once visited Fleming, the inventor of penicillin.
, because he benefited a lot from many viewpoints during his communication.
As for the purification of penicillin, Professor Bolvin already had his own method. Fleming, the inventor of penicillin, wanted to extract penicillin from the solution. The biggest problem he encountered was that penicillin was unstable and could not be evaporated by heating.
The water in the solution cannot be stored for long even at room temperature.
Professor Bolwin did the opposite. Instead of heating the penicillin solution, he froze the solution into a solid state, and then removed the air and lowered the air pressure to allow the water in the frozen solution to sublime.
This approach may seem incredible at first, but it is actually not difficult to understand. Place ice cubes in a closed environment at -20°C, remove the air, and reduce the air pressure until the air pressure is lower than the gas phase change curve, and the ice will transform into
The water vapor escapes. This method of first freezing and then removing the water through sublimation is called freeze-drying, or "freeze-drying" for short.
The only thing he lacks now is the method to produce penicillin on a large scale. The previous 40 units per square centimeter could not be used on civilians at all, and would only make penicillin a drug used by the upper class. This is not what Professor Bolvin wants, although he previously worked for Romania
He produced mustard gas, but he stopped researching that murderous thing during World War I. Now he focuses on medicine. Fortunately, these years of research have finally yielded results.
Professor Bolwin looked at this penicillin, his eyes filled with joy. He already had several ideas in his mind, using this as a method to further cultivate the mother strain of penicillin.
He is very clear about the role of penicillin. This is a great drug that can change the world. A large number of diseases, including tuberculosis, will have a chance to be cured. Before this, these people can only wait to die. In addition, it can treat wound inflammation.
It also has miraculous effects on a range of ailments.
