Academy, back mountain, experimental building.
Behind the attic, a huge glass greenhouse was erected on the ground. The greenhouse was divided into several small rooms, each of which was airtight and equipped with glass windows. It's like a huge compartmentalized constant-temperature incubator.
Li Ang, wearing a mask, was standing in the incubator at the moment. He was wearing a white coat sewn by Chai Chai. He scanned the greenhouse with a serious expression to see if there was anything missing.
A simple thermometer made of mercury is hung on the wall of the greenhouse, and heating talismans written by himself are pasted on the floor, forming a constant-temperature workshop.
Complete indoor sterilization and disinfection,
And through the isolation buffer room and sterile access door, equipment such as inclined mother bottles, shake flasks, seed tanks, propagation tanks, fermentation tanks and other equipment required for experiments were moved in.
Due to his previous contributions and good reputation, the materials for these expensive equipment were all reimbursed by the academy. Tantai Leshan, Su Feng and other businessmen and doctors responded to requests and provided all support.
However, Li Ang did not have 100% confidence in his heart.
He turned around, waved towards the firewood outside the greenhouse, and then used his mind power to close the door of the isolation buffer room from a distance.
The ideal drug against Treponema pallidum, or Treponema pallidum, is penicillin.
The reproduction cycle of Treponema pallidum is 30-33 hours, and penicillins have lactamases that can bind to proteins, causing damage to the bacterial cell wall and blocking the reproduction of Treponema pallidum.
Since the human body has no cell walls, penicillin kills germs without damaging human cells, making it an excellent antibiotic.
However, the difficulty of refining lies in culture, fermentation, separation and purification. .
If there is any deviation in any step, the efficacy of the medicine may be lost, and it may even change from a life-saving medicine to a killing medicine.
"let's start..."
Li Ang breathed a sigh of relief.
Everything was kept simple. If there was no good strain, I started cultivating it myself using leather boots, oranges and pumpkins.
If there is no corn extract required for fermentation, cottonseed cakes made from the residue left after the cottonseed oil is squeezed out are used instead of corn enzymatic compounds.
If you don’t have a stainless steel fermentation tank, use a small-mouth glass bottle.
If there is no refrigeration room, just use Liliangfu...
Li Ang was completely immersed in the refining of penicillin, sleeping only a few hours a day. Due to the lack of a mixer and shaker, he needed to enter the constant-temperature culture room regularly, holding the fermentation bottle and shaking it.
In the absence of an air compressor, use an air pump to introduce air into the bottom of the fermentation tank through a pipe equipped with degreasing sterile cotton and sterilizing filter cloth to ensure that there is sufficient dissolved oxygen in the culture solution.
The whole process is extremely cumbersome and complex, time-consuming and labor-intensive.
Yang Yu, Li Wei and others came to see him every day at first, telling him about the recent events in the academy through the walls of the glass greenhouse.
What kind of microscope caused an uproar in the scientific community? Every doctor in the academy has a microscope. Some doctors don't even attend classes. They spend every day in the office observing the minute structures of flowers, birds, insects, and fish.
The dignitaries of Chang'an were also proud to own a microscope. The higher the magnification, the greater their financial strength.
Ordinary people were a little panicked at first. After all, countless bugs have been discovered in the water. There are even countless bugs on things, people's faces and hands.
But as time went by, they got used to it. After all, the bugs were invisible to the naked eye. This also made more people have the good habit of drinking boiled water.
On the other hand, Zen Buddhism and Taoism are also fighting louder and louder. Zen Buddhism's theory is that "84,000 insects in the water" and "all things have animism", while Taoism uses the theory that "drinking water is killing living things" to attack the monks. hypocritical.
Su Feng, a doctor of science who is keen on watching people quarrel, also secretly got involved in the struggle between the two factions.
He took on more than a dozen pen names and published articles in different publications. Sometimes he supported Zen Buddhism, sometimes he supported Taoism, and sometimes he even inexplicably supported Manichaeism.
It is claimed that countless small insects invisible to the naked eye are actually the light and dark factors mentioned by Manichaeism. What Manichaeism said is true, and it has attracted a lot of hatred for Manichaeism.
The sun and the moon are passing by, and a month has passed quickly. Yang Yu and Li Wei feel that they are about to break through the intermediate level of the hiding realm, and the time for visiting is gradually decreasing.
Only Chai Chai and Li Leling were left, coming to visit Li Ang regardless of rain or shine.
He Fanshuang would occasionally be pulled over by Li Leling to post class notes on the wall of the glass greenhouse to make up lessons for Li Ang.
In addition, there is Qiu Feng, the daughter of the imperial physician. She heard that Li Ang was developing a new drug for epidemic diseases and came here to watch because she was handy and majored in reading, so she could help shake the fermentation bottle.
After Li Ang thought about it for a while, he allowed her to enter the constant-temperature sterile work room as his assistant.
But the refining of penicillin was still not smooth.
Fail, fail, fail.
Li Ang cultivated bacterial strains and repeated experiments over and over again. Sometimes he even wanted to apply to the Mountain Chief who had returned to the academy to see if he could use the alienated objects in Dongjun Tower that were said to be able to control time, so that he could have a better day. 24 more hours.

There is a long queue stretching under the Mingde Gate. Farmers, businessmen, and tourists who want to enter the city have to wait here and have their documents checked by the city gate guards before they can enter the city.
In the queue waiting to enter the city, there were roosters crowing, dogs barking, cows mooing, and people's voices noisy. Many people's eyes were focused on a group of misfits.
Turks.
In other words, the Turkic mission.
Most of them do not wear turbans and have beards, and their faces are particularly rough due to the scorching sun and wind and sand.
The sturdy Turkic guards loyally guarded the carriage, looking intently and ignoring the pointing and comments of the people around them.
Their hair accessories, their earrings, their wolf tooth decorations, crossbows, leather armors, waist knives, and leather boots have all become topics of conversation and even jokes for the Yu people.
The bureaucrats of Honglu Temple who accompanied them turned a blind eye to this, and had no intention of letting the compatriots of Yu State stop talking.
"A hundred years ago, no, fifty years ago, these Yu people should have been afraid of us."
In the mission carriage, a 14- or 15-year-old Turkic girl took back her palm that lightly lifted the curtains and spoke to her brother in Turkic language.
"Times have changed."
The young man in the carriage shook his head and said: "The State of Yu is stronger than ever.
Their armor is stronger than ours, their swords are sharper than ours,
Although their horses were not as numerous as those of the Turks, the Yu people had money and could buy good horses from Zhou, from overseas, and even from the far west.
In ten years, fifty years, or one hundred years, they can always breed enough war horses.
What's more, they still have a school palace. "
"We have them too!"
The Turkic girl raised her voice, but fortunately the carriage was covered with thick fur, so the sound was not heard.
"It's just a counterfeit."
The young man shook his head and said: "Our Wolf Garden was built by Mr. Zhang Yuan more than fifty years ago after imitating the Academy.
Mr. Zhang Yuan brought books, herbs, and craftsmen to the Turks, helped us formulate a calendar, build water conservancy, optimize sheep breeds, and improve weapons.
The Great Khan admired him very much and made him a Qilifa, and even made him a Yehu.
And those tribes looked down on him and despised him at the beginning, but gradually admired him and recognized his contribution. No longer calling him by his first name, but calling him sir.
Zhang Yuan was a great man of the Turks, but in the Yu State, he was just an abandoned disciple who had not even been admitted to the academy.
Think about it, my sister. "
