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, who was 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.

On the wall of the conservatory is a simple thermometer he made with mercury, and on the floor is pasted a heating talisman written by himself, forming a constant temperature workshop.

Indoor thorough sterilization,
And through the isolation buffer room and the sterile passage door, the inclined mother bottle, shaker flask, seed tank, breeding tank, fermentation tank and other equipment required for the experiment were moved in.

Due to 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 [-]% 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.

Since the human body has no cell wall, penicillin is an excellent antibiotic because it kills germs without damaging human cells.

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.

Keep everything simple, without good strains, start cultivating with leather boots, oranges, and pumpkins,
If there is no maize extract required for fermentation, the cottonseed cake made from the residue left after the cottonseed is pressed for oil is used instead of maize enzymes.

If you don't have a stainless steel fermenter, 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, shake and hold the fermentation bottle,
In the absence of an air compressor, an air pump is used to introduce air into the bottom of the fermenter through a pipeline equipped with absorbent 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, and told themselves what happened in the academy through the walls of the glass conservatory.

What kind of microscope has caused an uproar in the field of science. Dr. Xuegong has a microscope in his hands. Some doctors don’t even take classes. They observe the fine structure of flowers, birds, insects and fish in the office every day.
And the dignitaries of Chang'an are also proud of owning a microscope, the higher the magnification, the more financial resources they can show.

Ordinary people were a little panicked at first, after all, they have found countless bugs in the water, even on things, people's faces and hands, there are countless 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 theory of Zen is "[-] 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 adopted more than a dozen pseudonyms and published articles in different journals. He sometimes supported Zen Buddhism, sometimes Taoism, and sometimes even supported Manichaeism for no reason.

Claiming that countless bugs 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.

The sun and the moon flowed like a stream, and a month passed quickly. Yang Yu, Li Wei and the others felt that they were about to break through the middle level of the Tibetan Realm, and the time to visit gradually decreased.

Only Chai Chai and Li Leling were left to visit Li Ang regardless of the weather.

He Fanshuang would occasionally be pulled over by Li Leling to stick 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, so she came to watch because she was ingenious and 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 bacteria 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 Dongjun Building to make himself a day 24 hours extra.

----

Under the gate of Mingde, there was a long queue. Farmers, businessmen, and tourists who wanted to enter the city had to wait here, and the city gate guards checked their documents before entering the city.

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.

Turks.

In other words, 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 sturdy 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.

But 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's a hundred years ago, no, 50 years ago, these people should be afraid of us."

In the carriage of the mission, a Turkic girl of fourteen or five years old withdrew her palm from lightly lifting the curtain, 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, overseas, and even places in the far west.

Ten years, 50 years, 100 years, they can always breed enough war horses.

What's more, they still have a school palace. "

"We have it too!"

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 [-] 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, improve weapons,
The Great Khan admired him so much that he granted him the title of Tulifa, and even made him Yehu,

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 was just an abandoned student who didn't even get into the academy.

Think about it, my sister. "
