Shi Xiong took the small bottle with a little excitement, looking at the pinch of gray powder in the small bottle as if looking at a peerless treasure.

　　 "Let, is the purification process mature? Can you and your team now purify this penicillin in a large amount?" After a long time, Shi Xiong raised his head and asked Agust.

Agusta sighed and shook his head: "Boss, according to your prompt, we now have mastered the process of purifying penicillin, but this process is not mature yet and we need to improve it. If we use the current purification process to purify penicillin, , With such a small amount of penicillin, we need at least a week."

　　 These words made Shi Xiong scratch his scalp a little bit blindly. He frowned and groaned and said, "Go, go to your laboratory."

Qiao La Krulu immediately walked outside and whispered to the duty officer standing outside: "The Chief Chief has very important things to do today, so he won't see anyone today. If someone comes, you just push it away. Or let them come back tomorrow. If there is something very important, you can let me know."

The duty officer nodded heavily, and Joe Laklulu immediately followed in the footsteps of the stone bear. The three men, under the protection of a dozen guards, rode in a low-key four-wheeled carriage, and quickly moved towards the Bear Palace. The Yanhuang Institute of Science and Technology in the southeast drove away.

The Yanhuang Institute of Science and Technology is currently the highest scientific research institution of the Yanhuang tribe. It is home to many alchemists and scientists from Europe, as well as various scientific research talents cultivated by the Yanhuang tribe over the years. Its status in the tribe and the status of this era The status of the Royal Academy of Sciences in the UK is the same.

　　 From the first four alchemists who followed the stone bear, to the eighteen arhats, and now hundreds of alchemists and scientists, the Yanhuang Institute of Science and Technology is now the largest scientific research institution of the entire Yanhuang tribe. The numerous ongoing projects of the Yanhuang Empire are inseparable from the technical support of the Yanhuang Science and Technology Institute.

　　 Like the Carlos that is being tested in the far east, it would not be possible to launch the ship without the technical support of the Yanhuang Institute of Science and Technology.

　　 There are also the Chicago Canal currently being excavated, the Erie Canal and the Wayland Canal that are being excavated, all of which are inseparable from the technical support of the Institute of Science and Technology. In addition, the main roads under construction also have a large amount of technical support from the Yanhuang Institute of Science and Technology.

Although 　　 Yanhuang Institute of Science and Technology is located in the city center of Shangjing, it covers an extremely large area, even larger than that of the Giant Bear Palace. And there are no commercial or residential areas around here, and the environment is very quiet. And there are two entire regiments of Grim Bear soldiers stationed and protected around here, so that the security level here surpasses that of the Bear Palace.

　　 The stone bear came from the soul of later generations, and he naturally knew the preciousness of these researchers.

　　 In today's era when the Yanhuang tribe is waiting to be rejuvenated, the preciousness and importance of these scientific researchers even exceeds that of the Grim Bear Army.

　　 The four-wheeled carriage that the stone bear rides has the unique symbol of the Great Bear Palace-a giant bear with its head up and roaring, so even if the carriage has passed more than a dozen checkpoints along the way, no one will stop it.

　　 Everyone recognizes a driver who drives a car—that's the personal guard of the deputy commander of the Guards and the Great Chief, the Son of God.

　　 The car quickly entered the quiet science and technology institute, and then quickly came to a relatively independent courtyard, here is the site of Jean Agusta, the Royal Academy of Science and Technology Medical Park.

　　 After getting out of the car, Stone Bear and Joe La Krulu led by AgustaWestland came to a very strong and huge house, outside there were dozens of Grim Bear soldiers guarding them with guns and live ammunition. After seeing the arrival of Shi Xiong in person, these dedicated soldiers raised their hands in salute with a fanatical expression on their faces.

　　 But no one made any noise.

　　 Shi Xiong also raised his hand to salute, and then hurriedly walked into the big house.

　　 As soon as he entered, a rush of heat rushed toward his face. About thirty people in white coats were busy inside.

　　 Walking into this room, Shi Xiong was in a daze for a while. If he is not sure that he is now in the 1870s, he would really think he came to the laboratory when he was in college.

In this huge house, you can see all kinds of test equipment everywhere. Various shapes of glassware and metalware are flooded in this room. Numerous scientific researchers are doing all kinds of experiments without distraction. test.

　　 They didn't even see the arrival of Shi Xiong.

　　 Stone Bear didn't bother them either, and under the leadership of Agusta, he went to a much smaller room next to the big house. There are also many bottles and cans and various test utensils.

"Boss, this is the petri dish of penicillin." Argus said when he walked to a sealed glass room the size of a double person. In this sealed glass room was placed a piece of glassware of various sizes. "Our penicillin is cultivated in these vessels, and the temperature and humidity in the glass room are controllable."

　　 Ishikuma nodded slightly when he looked at the glassware of various sizes, filled with brownish-yellow culture medium, and a handful of blue-gray moldy substances floating in the medium.

"Now we can cultivate penicillin strains on a large scale. It is not difficult to cultivate this thing. As long as the temperature and humidity are controlled, a large amount of culture can be carried out in a short period of time. However, it is the purification of penicillin that we have not yet found. Large-scale and stable extraction method~lightnovelpub.net~ Shixiong nodded again. As a guide on how to cultivate penicillin and purify penicillin, he naturally knows that the real penicillin is not those blue-gray moldy substances, but exists in In these cultures, only the penicillin purified in these cultures is the real penicillin.

　　 It’s just that penicillin is mixed in the culture medium. If it is not purified, this culture medium is difficult to store at room temperature for a long time.

　　 Therefore, in order to get real penicillin, it must be purified from these culture fluids.

But the problem is that although the purified penicillin is in powder form, it is an out-and-out solid in the physical state. To purify the solid from the liquid, the liquid is generally changed by heating. For the vapor to evaporate, the dissolved penicillin can be precipitated out.

　　 is like the exquisite table salt made by the stone bear after the soul has been worn to this era. In fact, it is a process of using evaporation to purify the table salt.

　　 The purification of partial penicillin is not possible with this method. Because penicillin bacteria cannot tolerate high temperatures, once the temperature is too high, even if penicillin is purified, the purified penicillin is useless.

In the original historical time and space, Alexander Fleming, who was the first to discover penicillin, was troubled by this link for more than ten years. It was until 1939 that Australian pathologist Howard Walter Flory and German Biology The chemist Ernst Chann began to try other methods to purify penicillin. This method of purifying penicillin is freeze-drying!
