Murong Youheng was stunned for a moment, he hadn't thought of this method at all. In fact, don't say that he didn't expect it, even Dr. Fleming, who discovered penicillin, did not think of purifying penicillin with this method after ten years of research, and it was not until 1939 that Florey and Qian used freeze-drying to extract the crystals of penicillin, and then used penicillin for clinical trials.

"Freeze-drying?" Murong Youheng lowered his head and pondered, his mouth was still muttering: "Cool and freeze penicillin into a solid in advance, and then make the water vapor directly sublimate under vacuum conditions, and penicillin itself remains in the ice shelf when it is frozen, forming crystals, so that the purity of penicillin can be reached, and its crystals can be extracted." ”

Murong Youheng's eyes suddenly lit up, he slapped his forehead heavily, and said excitedly: "This is indeed a good way, why didn't I think of it?" As he spoke, he eagerly asked Qin Feng: "Ziyi, do you know its specific parameters, such as what temperature it is frozen to, and what is the absolute pressure during the drying process?" If there are such parameters, I guarantee that I will be able to extract high-purity penicillin crystals. ”

Qin Feng only remembered that he could use the freeze-drying method to extract the crystals of penicillin, as for the parameters, he didn't know the parameters, so he shook his head and said: "I also heard that someone has tried to use this method to successfully experiment, but how do I know the specific parameters?" ”

Murong Youheng was a little disappointed for a moment, but he asked strangely: "Ziyi, you said that someone used the freeze-drying method to successfully experiment?" So why have I never seen this material, and is anyone looking at this penicillin now other than Dr. Fleming? ”

"Oh, this, I also heard from my English friend at the beginning, he said that since the publication of Dr. Fleming's paper, some people have studied penicillin, and one of them is a man named Brown who has successfully extracted penicillin crystals using this method. However, the man, Brown, was soon killed by a fire in his laboratory. His research results were only mentioned to my friend, but all the research materials and parameters were burned in that fire, and nothing was left. Qin Feng had already thought of his words and hurriedly replied.

After Murong Youheng heard the news, he shook his head with regret and sighed, "It's a pity." Then, Murong Youheng thought for a while and said, "However, since the crystals of penicillin can be extracted by freeze-drying, then we will verify this method completely through experiments, and once the experiment is successful, we can also obtain the best parameters from the experiment." The more Murong Youheng spoke, the more excited he became, he glanced at the simple experimental equipment in his study, and said, "No, the experimental equipment here is too backward, I have to go back to the United States immediately and go to the laboratory of the pharmaceutical factory to conduct experiments." ”

"I said Brother Heng, don't be so anxious, okay. I've already bought the patent from Dr. Fleming, and when we buy Pfizer, you're the chief engineer for the project. Qin Feng shook his head with a smile and said.

Ziyi is right. After we buy Pfizer, you have to go all out to develop penicillin, and if this penicillin is really as amazing as you and Ziyi said, it will be really good. At this time, Murong Qi, accompanied by Murong Qingqing, walked in with a smile.

As soon as Qin Feng saw Murong Qi coming in, he hurriedly stepped forward and bowed, and said gratefully: "Yue Fei, this time you were able to support and participate in the acquisition of Pfizer Pharmaceutical Company, and my son-in-law is grateful." ”

"Where, where." Murong Qi waved his hand and said with a smile: "Pfizer Pharmaceutical Company also has a good reputation in the United States, and Youheng works there again, I don't think I can miss such an opportunity." ”

"Yes, brother, penicillin is really as amazing as you said, then we can make a fortune together. Brother, you must get this penicillin out. Murong Qingqing said with a smile.

"Whether penicillin can be made or not, I definitely can't do it alone, I need a team working together. Moreover, Ziyi just told me that the use of freeze-drying method to purify penicillin, although it is theoretically feasible, still needs to be experimentally demonstrated. When it comes to scientific issues, Murong Youheng has always been quite rigorous, and said with a frown.

"Big brother, I know you can do it." Murong Qingqing walked to Murong Youheng's side, took his arm and said with a smile.

In fact, Qin Feng has always had a question about why Murong Qi participated in the acquisition of Pfizer Pharmaceutical Company. You must know that Murong Youheng is an employee of this company, and no one knows the current situation of Pfizer better than him, and Murong Youheng also proposed to Qin Feng to let him consider it carefully. As for penicillin, I'm afraid that even Murong Youheng doesn't know if penicillin can be developed and whether it can play the role that Qin Feng said.

However, Murong Qi didn't say it, and Qin Feng didn't want to ask. After having lunch at Murong's house, Qin Feng discussed with Murong Qi about the acquisition of Pfizer. Murong Qi didn't plan to go out in person, the acquisition matter was fully entrusted to Qin Feng, in his words, Qin Feng occupied a large share, and he would not suffer a loss if he entrusted it to Qin Feng, so why bother working hard.

After reaching an agreement with Murong Qi, the acquisition of Pfizer was officially launched. Three days later, Murong Youheng, who couldn't wait, took the initiative to ask for a matchmaking and rushed to the United States.

A month later, news finally came from the other side of the ocean that Smith and Murong Youheng had finally acquired Pfizer at a price of $2.8 million after negotiations with Pfizer in the United States. This price made Qin Feng feel very uncomfortable, because he knew that although Pfizer was on the verge of bankruptcy, the negotiations were still quite difficult. First of all, they are only willing to transfer 60% of the shares. If Murong Qi's shares are counted, Qin Feng alone will not be able to fully control it, and Qin Feng does not want Americans to enjoy the huge benefits brought by penicillin in the future. Later, Pfizer finally agreed to transfer all of the company's shares, but the proposed price was as high as $4 million. If Qin Feng's original psychological price can talk about three and a half million US dollars, and then subtract the five hundred thousand US dollars invested by Murong Qi, this price can still be affordable. Unexpectedly, the final transaction price turned out to be $2.8 million.

In the telegram, Smith praised Murong Youheng, who went to the negotiations together, and at first the negotiations were dominated by Smith, and then gradually turned into a direct confrontation between Murong Youheng and the board of directors of Pfizer. can talk about this purchase price, Murong Youheng is indispensable. Smith, who was already skeptical about Murong Youheng's ability, made a 180-degree turn to Murong Youheng at this time, and while not sparing words of praise, he completely agreed that Qin Feng wanted Murong Youheng to take the position of general manager of Pfizer Pharmaceutical Company.

Since Smith also took out $100,000 to buy shares, when the shares were finally allocated, the Murong family accounted for 30% of the shares, Smith accounted for 10%, and Qin Feng accounted for 60%.

After the completion of the acquisition, the development of penicillin was officially launched. In addition to telling Murong Youheng to use freeze-drying to purify penicillin, when he parted with Murong Youheng, Qin Feng also specially told Murong Youheng that there is a kind of melon that can produce penicillin in large quantities and can grow in a culture liquid made of corn. Naturally, Qin Feng also attributed this huge discovery to Dr. Brown, who died in the fire without leaving any research materials.
