Chapter 606

Stone bear some excited took over the small bottle, like looking at the peerless treasure, looking at the small pinch of gray powder in the small bottle.

"Let's see, is the purification process mature? Can you and your team purify this penicillin in large quantities now? " For a long time, the stone bear raised his head and asked Agust.

Agust sighed and shook his head: "chief, according to your tips, we have mastered the process of purifying penicillin, but this process is not mature, we need to improve. If we use the current purification process to purify penicillin, we need at least a week for such a small amount of penicillin. "

This made the stone bear scratch his scalp. He frowned and pondered for a while, and then said, "go to your lab and have a look."

Jorah krulu immediately went outside and said to the duty officer standing outside in a low voice: "today, the chief has a very important thing to do, so he won't see anyone today. If someone comes, you can just push them off or ask them to come back tomorrow or the day after tomorrow. If there's really something very important, ask someone to let me know. "

The duty officer nodded heavily, and jorak Lulu immediately followed the steps of the stone bear. Under the protection of a dozen Pro guards, the three people rode in a low-key carriage and quickly drove to Yanhuang science and Technology Institute, which is located in the southeast of giant bear palace.

Yanhuang Academy of science and technology is the highest scientific research institution of Yanhuang tribe at present. There are many alchemists and scientists from Europe, as well as various scientific research talents cultivated by Yanhuang tribe in recent years. Its status in the tribe is the same as that of the Royal Academy of Sciences in Britain in this era.

From the first four alchemists who followed Shi Xiong, to the later eighteen Arhats, to today's hundreds of alchemists and scientists, Yanhuang Academy of science and technology is now the largest scientific research institution of the whole Yanhuang tribe. At present, many ongoing projects of Yanhuang empire are inseparable from the technical support of Yanhuang Academy of science and technology.

For example, the Carlos, which is being tested in Dongdu, could not have been launched without the technical support of Yanhuang Academy of science and technology.

In addition, the Chicago canal being excavated, the Erie Canal and the Welland canal being prepared to be excavated are inseparable from the technical support of the Academy of science and technology. In addition, the main roads under construction also have a lot of technical support from Yanhuang science and Technology Institute.

Yanhuang Academy of science and technology is located in the center of Shangjing, but it covers an extremely large area, even larger than the giant bear palace. Moreover, there is no commercial area or residential area around here, and the environment is very quiet. Moreover, there are two regiments of soldiers stationed and protected around, which makes the security level here exceed that of the giant bear palace.

Stone bear came from the soul of later generations. He naturally knew the value of these researchers.

In today's era of Yanhuang tribe, the value and importance of these researchers even surpass that of the fierce bear army.

The carriage on which the stone bear rides has the unique symbol of the giant bear Palace - a giant bear head roaring up, so no one stopped the carriage even though it passed more than ten checkpoints along the way.

Everyone knows the driver - the deputy commander of the pro guard and the bodyguard of the great chief, the son of God.

The car soon entered the quiet Academy of science and technology, and then quickly came to a relatively independent courtyard, here is Jean Agust's territory, the Royal Academy of science and technology medical park.

After getting out of the car, stone bear and jorak Lulu, led by Agust, come to a very solid and huge house. There are dozens of bear soldiers with live ammunition outside. After seeing the stone bear coming in person, these conscientious soldiers raised their hands to salute with fanatical expression on their faces.

But no one made any sound.

Stone bear also raised his hand after saluting, and then hurried into the big house.

As soon as I went in, a stream of hot air came to my face. About 30 people in white coats were busy inside.

Entering this house, the stone bear was in a trance for a moment. If he wasn't sure that he was in the 1870s, he really thought he had come to the laboratory when he was in college.

In this huge house, all kinds of test instruments can be seen everywhere. Various kinds of glassware and metal utensils of different shapes are filled in this room. Many scientific researchers are concentrating on all kinds of experiments.

They didn't even see the stone bear coming.

The stone bear didn't disturb them either. Under the guidance of Agust, he went to a much smaller room next to the big house. There are also many bottles, jars and all kinds of test utensils.

"Chief, this is the penicillin dish." Agust went to a sealed glass room that was the size of a double, and said, "in this sealed glass room, there are pieces of glassware of different sizes." our penicillin is cultivated in these containers, and the temperature and humidity in the glass room are controllable. "

The stone Bear looked at the glassware of different sizes, which was full of brown culture medium and a handful of blue gray moldy substances floating in the culture medium, and nodded slightly.

"Now we can cultivate penicillin strains on a large scale. It's not difficult to cultivate. As long as we control the temperature and humidity, we can cultivate a large number of penicillin strains in a short time. However, for the purification of penicillin, we have not yet found a large-scale and stable extraction method

Stone bear nodded again. As the director of how to cultivate penicillin and purify penicillin, he naturally knew that the real penicillin was not those blue gray moldy substances, but existed in these culture media. Only the penicillin purified in these cultures is the real penicillin.

Only penicillin is mixed in the culture medium. If it is not purified, it is difficult to keep the culture medium at room temperature for a long time.

Therefore, in order to get the true penicillin, it must be purified from these media.

But the problem is that although the purified penicillin is powder, it belongs to solid in physical phase state. In order to purify the solid from the liquid, the liquid is usually evaporated by heating, and the dissolved penicillin can be separated out.

It's like the exquisite salt made by stone bear after the soul of this era. In fact, it's a process of purifying salt by evaporation.

But the purification of penicillin can't be done in this way. Because penicillin bacteria can not endure high temperature, once the temperature is too high, even if the 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 not until 1939 that Australian pathologist Howard Walter Florey and German biochemist Ernst chann began to try other methods to purify penicillin. This method of purifying penicillin is freeze-drying!
