Chapter 215 Greenhouse
School Palace, Back Mountain, Laboratory Building.
Behind the attic, a huge glass conservatory was erected on the ground. The conservatory was divided into several small rooms, each of which was airtight and equipped with glass windows. It's like a huge partitioned 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.
Hanging on the wall of the conservatory is a simple thermometer made of mercury, and on the floor is pasted a heating talisman written by himself, forming a constant temperature workshop.
Thorough sterilization and disinfection in the room,
And through the isolation buffer room and the sterile passage door, the inclined mother bottle, shake flask, seed tank, breeding tank, fermenter and other equipment required for the experiment were moved in.
Because of his previous contributions and good reputation, the materials for these expensive equipment were all reimbursed by the Academy, and Tantai Leshan, Su Feng and other Siye and doctors were more responsive and provided all support.
However, Li Ang did not have 100% confidence in his heart.
He turned around, waved to Chai Chai outside the greenhouse, and then used his thoughts to close the door of the isolated buffer room.
The ideal drug against Treponema pallidum, or Treponema pallidum, is penicillin.
The reproduction cycle of Treponema pallidum is 30-33 hours, and penicillins have lactamase, which can bind to protein, causing damage to the bacterial cell wall and blocking the reproduction of Treponema pallidum.
Because the human body has no cell wall, penicillin can kill germs without damaging human cells, so it is an excellent antibiotic.
However, the difficulty of refining lies in cultivation, fermentation, separation, and purification. .
Any deviation in any step may lose the efficacy of the medicine, and even change from a life-saving medicine to a killing medicine.
"let's start"
Li Ang let out a long sigh of relief.
Everything is kept simple, there are no good strains, so I start cultivating with leather boots, oranges, and pumpkins.
There is no maize extract required for fermentation, so the cottonseed cake made from the residue left after the cottonseed oil is squeezed is used instead of maize enzymes.
If there is no stainless steel fermentation tank, use a small glass bottle.
If you don’t have a refrigerator, use Li Liangfu.
Li Ang was completely immersed in the refinement of penicillin, and he only slept for a few hours a day. Because of the lack of agitator 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, an air pump is used to introduce air into the bottom of the fermenter through a pipe equipped with degreased sterile cotton and sterile filter cloth to ensure sufficient dissolved oxygen in the culture medium.
The whole process is extremely tedious and complicated, time-consuming and labor-intensive.
Yang Yu, Li Wei and others came to see themselves every day at the beginning, telling themselves what happened in the academy through the glass conservatory wall.
What kind of microscope has caused an uproar in the field of science. Dr. Xuegong has a microscope, and some doctors don’t even take classes. They observe the fine structure of flowers, birds, insects and fish in the office every day.
The dignitaries in Chang'an are also proud of owning a microscope. The higher the magnification, the more financial resources they can show.
Ordinary people panicked at first, after all, they have found countless bugs in the water, even on things, people’s faces and hands, there are many bugs,
But as time went by, I got used to it. After all, those bugs are invisible to the naked eye-this also makes more people have the good habit of drinking boiled water.
On the other hand, the rhetoric of Zen and Taoism is getting louder and louder. The Zen theory is "84,000 insects in the water" and "everything has animism", while Taoism criticizes monks with the theory that "drinking water is killing life". 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 more than a dozen pseudonyms, published articles in different publications, supported Zen Buddhism for a while, Taoism for a while, and sometimes even supported Manichaeism for no reason.
Claiming that countless worms invisible to the naked eye are actually the light and dark factors that Manichaeism said, and what Manichaeism said is true, and it has attracted a lot of hatred for Manichaeism.
Only Chai Chai and Li Leling were left, and they came to visit Li Ang regardless of the weather.
He Fanshuang would occasionally be pulled over by Li Leling to paste the class notes on the wall of the glass conservatory to make up lessons for Li Ang.
There is also Qiu Feng, the daughter of the imperial physician. She heard that Li Ang was developing a new drug against the epidemic, and she came to watch specially because of her ingenuity, and she also majored in studying, so she could help shake the fermentation bottle.
After thinking about it for a while, Li Ang allowed her to enter the constant temperature and sterile workshop as his assistant.
But the refining of penicillin is still not smooth.
Fail, fail, fail.
Li Ang cultivated the strains over and over again, repeated experiments, and sometimes he even wanted to apply to the head of the mountain who had returned to the academy to see if he could use the alienated object that was said to be able to manipulate time in the Dongjun Building to make himself a day 24 hours extra.
——
Under the gate of Mingde, there is a long queue. Farmers, businessmen, and tourists who want to enter the city must wait here, and they can only enter the city after the city gate guard checks their documents.
In the queue waiting to enter the city, roosters crowed, dogs barked, cows mooed, people were noisy, and many people's eyes were focused on a group of people who didn't fit in.
Turkic people.
Or, the Turkic Mission.
Most of them don't wear headdresses, have beards, and their faces are extraordinarily rough due to the scorching sun and wind and sand.
The well-built Turkic guards loyally stood beside the carriage, without turning their eyes, ignoring the pointing and discussion of the surrounding people.
Their hair ornaments, their earrings, their mace decorations, crossbows, leather armor, waist knives, and leather boots have all become the stuff of talk and even jokes for Yu people.
The bureaucrats of the Honglu Temple who accompanied them turned a blind eye to this, and had no intention of stopping the Yu country compatriots from talking.
"If it were a hundred years ago, no, fifty years ago, these people should have feared us."
In the carriage of the mission, a Turkic girl of fourteen or five years old withdrew her hand that raised the curtain lightly, and said to her brother in Turkic.
“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 are not as many as the Turks, the Yu people are rich and can buy good horses from Zhou State, overseas, and even places in the far west.
Ten years, fifty years, one hundred years, they can always breed enough war horses.
Besides, they still have a school. "
"So do we!"
The Turkic girl raised her voice, but fortunately the carriage was covered with thick fur, so it didn't spread.
"It's just a counterfeit."
The young man shook his head and said: "Our wolf garden was established by Mr. Zhang Yuan imitating the academy more than 50 years ago.
Mr. Zhang Yuan brought books, herbs, and artisans to the Turks, and helped us formulate a calendar, build water conservancy, optimize sheep breeds, and improve weapons.
The Great Khan admired him very much, and granted him the title of Tu Lifa, and even made him Ye Hu,
And those tribes looked down on and despised him from the beginning, and gradually admired him and recognized his contribution. Instead of calling him by his first name, he was called Mr.
Zhang Yuan is a great Turkic man, but in Yu State, he is just an abandoned student who didn't even get into the academy.
Think about it, my sister. "
