"Die? Why did he die? Didn't he say that the Erlangjun of Duke Tang's Duke lived, how could he die?"

"When you go back to your Majesty, the Erlangjun of Duke Tang was cured, but in another trial, a patient still died of penicillin No. 17."

"In other words, was Li Erlang's recovery purely by chance?"

"It's not a coincidence to go back to Your Majesty. After all... Your Majesty, please go here."

In a workshop, in a constant temperature laboratory, Yu Wenwen, wearing a white coat, a hat and a mask, visited the Penicillium culture room under the leadership of Lu Wenhua. A large number of glass dishes were placed in the glass windows, and Penicillium colonies of large and small growing on the culture medium.

The group stopped in front of a glass window. Yu Wenwen carefully looked at the penicillium colonies in several of the glass dishes. After a while, he could not see any difference.

In his opinion, all the penicillium cultured in the laboratory is the same, and Li Erlang was cured by penicillin and is very good news. Now it seems that he will be given a discount.

That day, facing a father's plea, Yuwen Wen decided to lend a helping hand and let his secret medical power try it out. However, the success rate of using penicillin to treat the disease was very low, so he explained the interests to Li Yuan in advance.

First of all, there are ways to cure the disease. Whether it can be cured depends on fate. Whether it is successful or not, it must be kept confidential. If the incident is successful or not, it must be kept confidential. If the news leaks out, haha.

Li Yuan, who was in a hurry to seek medical treatment, agreed immediately, and in the end, the matter had a happy ending: the young child Li Shimin's illness was cured.

For Yuwen Wen, this is also good news: there is a breakthrough in the development of penicillin.

He immediately ordered his men to conduct the experiment and waited for good news with anticipation, but the reality was cruel.

The penicillin injected by Li Shimin was used in the same batch of products for the treatment of other lung patients in Chang'an City. Four of the five people who received the treatment died.

Therefore, the fact that Li Erlang was cured by penicillin was more like a low-probability event.

Yu Wen Wen was very depressed when he learned the result. He asked someone to take the pre-prepared celebration wine (drinking and drinking wine) to water the flowers, and he was stuck in the study and stared blankly.

He couldn't swallow this, so he took a slight breath and went out of the uterus to the laboratory. After this, he learned the results of another group of trials: four more died in the other five patients treated with penicillin.

Is the patient who survived benefiting from penicillin injection?

At this moment, the depressed Yuwen Wen looked at the penicillium in the glass dish and was fascinated by the spirit. Lu Wenhua continued to explain: "Your Majesty, this time, it's really a breakthrough..."

"Pesinocchia No. 17 is a strain we carefully screened. It is cultivated in the laboratory and has good sterilization effect. Its effectiveness is many times stronger than that of Penicillium before..."

"This time, the reason why patients die of allergies is not a problem with bacterial strains, but a problem with purification technology. Because it cannot effectively remove impurities, the impurities contained in it cause skin allergies..."

"But the penicillin it contains is indeed effective, so the son of the Duke of Tang was cured. As for other patients who injected the same batch of products but died of severe allergies, I believe that the purification technology is not good, which leads to the purity of the same batch of products being different."

When Yuwen Wen heard this, he thought for a moment and asked: "That is to say, even if he really found a highly efficient penicillin species, if there is no breakthrough in purification technology, it will be impossible to stably extract penicillin?"

"Yes, this technical difficulty is even more difficult than finding efficient bacterial species. If it is not solved, penicillin will not be practical for treating people."

Lu Wenhua then gave an example: "Take this No. 17 penicillin product as an example. Some of the penicillin extracted in the same batch can save people, but most of the products will cause allergies to die. Such an unstable drug is like gambling when used to cure diseases."

"Purification..." Yuwen Wen pondered and looked at Lu Wenhua: "How do you plan to solve this problem?"

"Your Majesty, I'm afraid you have to put the technical solution..." Lu Wenhua hesitated for a moment, and finally mustered up the courage: "I'm afraid I have to put the technical solution back on it. In other words, the existing purification technology may be incorrect in the research direction. If you continue to study it, it may be difficult to make a breakthrough."

Yuwen Wen looked at Lu Wenhua and suddenly felt powerless. He had invested countless funds to develop penicillin, but now he is still...

Taking a deep breath, Yuwen Wen asked again: "I want to know, can this problem be solved as long as you are willing to spend money?"

"Your Majesty, you may not be able to study it if you spend money, but you cannot do it without spending money."

"That's it..." Yu Wen Wen looked at the penicillium in the glass dish in front of him, and after a moment of silence, he spoke: "You apply as soon as possible, and I will definitely approve the funds required."

When Lu Wenhua heard this, he was overjoyed: "Yes!"

Several other experimenters who accompanied the tour also showed joy when they heard this. They had spent more than ten years developing penicillin. Now they have finally found high-efficiency bacterial seeds, but they are afraid of giving up halfway.

Yuwen Wen looked at the glass dishes attentively, as if looking at priceless treasures: "Is this bacterial species really efficient?"

"Yes, your majesty, it took us more than ten years to finally find the right strain."

"Well..." Yuwen Wen didn't think that Lu Wenhua would lie to him. He knew that the first difficulty in developing penicillin was to find efficient penicillin species, just like farming requires high-yield rice seeds.

If the seeds are not good, no matter how hard they water and fertilize them, there will be no good harvest. For penicillin, this is the function of good bacteria.

With good seeds, when the harvest season comes, if the technology fails when the rice is unhulled, it will lead to a large amount of white rice loss and also be doped with various impurities, which will directly affect the yield. For penicillin, this is the role of purification technology.

Two technical difficulties must be solved all of them before penicillin can be used to treat people, rather than as veterinary medicine.

The first technical difficulty is that continuous experiments can be used to screen highly efficient bacterial species, but this trial has been more than ten years.

Yuwen Wen looked at Penicillium, feeling mixed feelings, and then was a little excited: I have spent so much money over the past decade, but after all, I have gained something...

His mood improved, and he felt that these penicilliums looked very pleasing. He wanted to describe these treasures, but he didn't know what words to use to describe them.

As he thought about it, Yuwen Wen thought of a word: Weird.

The original meaning of strangeness refers to strange and beautiful flowers. Although the penicillium in front of you is not a flower, it is not suitable to compare it to green grass. Yuwen Wen just read the "Fu of Beauty" by Sima Xiangru of the Western Han Dynasty not long ago, and he still remembers the paragraphs in it:

Weird and elegant, beautiful and elegant.

He felt that the efficient Penicillium species represent a bright future, and can be compared to flowers or to beauty.

But after thinking for a long time, I really couldn't connect Penicillium with beauty, otherwise I would become a "mold" woman.

But soon, Yuwen Wen remembered another sentence: The money was not really spent, it was just a different way to stay by your side.
