In the clean room, many people in white coats were busy beside the rectangular window-style platform, with flat glassware with covers arranged neatly.

Each glass dish has a label with a different number written on it.

Those in white coats also wore cloth hats and masks, holding porcelain plates in their hands. From time to time, they opened a glassware, clamped up the things in the porcelain plates with tweezers, and placed them on the translucent paste inside the glassware.

Outside the room, in front of the glass window, the emperor Yuwen Wen, who came to visit after dinner, looked at the movements in the room and remained silent.

He knew exactly what these people were doing, and the familiar scene made an experimental process appear in his mind.

The first step is to mix the juice cooked from taro and the juice made of rice, make a culture medium, and pour it into a round and flat-bottomed glassware.

In the second step, "seed" the obtained penicillium on the culture medium and cover it with a lid (there are small holes in the lid).

The third step is to incubate at room temperature of about 25 degrees for seven days.

Step 4: Pour some liquefied culture medium into the funnel, which contains "filter paper" in the funnel. Filter the liquid, inject vegetable oil into the filtered liquid and stir evenly, and let it stand.

The liquid will be divided into three layers, the upper layer is a fat substance, the middle layer is an insoluble substance, and the lower layer is a liquid substance (filtrate). Open the opening below the container and release the lower layer of filtrate.

Step 5: Purify the filtrate: Add the filtrate to the boiled (sterilized) bamboo charcoal powder, then stir to allow the toner to absorb the substances in the filtrate, then put the toner into the funnel, pour in distilled water, and wash away the impurity.

Add acid water at a specific concentration made of rice vinegar, add alkali water at a specific concentration to obtain a purified filtrate.

Step 6: Effect determination: Get pus from the suppurated wound in advance, cultivate mold in a glass petri dish. At this time, divide the purified filtrate into a certain number, drop it onto a clean sheet of paper, and then put the sheet of paper into the culture medium where the mold is cultivated.

A few days later, if there is an open space around the paper sheet (mold dies), it means that the filtrate is effective. If the mold has no changes, it means that it is invalid.

Step 7: Refining: Collect the filtrate that is effective for mold in a small pot, prepare a piece of clean paper with strong water absorption, and the paper is in a long shape. Soak one end in the small pot and hang the other end.

This piece of paper will absorb water and suck up the filtrate in the small basin.

The substances in the filtrate have different heights of "rise" on paper, so various mixed substances are "separated" on paper, which is the on-paper chromatography method.

Cut off the wet part on the top and put it in a Petri dish to continue culturing. The result of repeated repetition is...

Congratulations on getting penicillin!!!

Yuwen blinked, pinched off his fantasy, and looked at the factory in front of him, a deep sense of frustration arose in his heart.

When he turned to the "tasting room" next to him, he felt a smell of mixed smell and fragrance coming towards him. He looked at the red fermented bean curd, white fermented bean curd and green fermented bean curd prepared by the staff. He picked up chopsticks, picked up a piece of green fermented bean curd and put it in his mouth.

After biting it, the slight smell is left between the teeth. The product quality of Yecheng fermented bean curd workshop is already very stable, and the food safety is guaranteed. It can provide red, green and white fermented bean curd to the market in large quantities.

The entourage also tasted the fermented bean curd produced in the workshop. This special food originated from the people and grew up in Xiyang, Huangzhou. Because of its unique flavor, it was very suitable for serving porridge or cooking seasonings. In addition, it was cheap, so it was quickly accepted by the people.

The fermented tofu workshop in Xiyang City can produce this food in large quantities. The fermented tofu is not easy to deteriorate and is convenient for long-distance transportation, so it soon became popular in Shannan area.

With the opening of Jiangling, Rangcheng, Xiangyang, Luoyang, Chang'an, Xuanhu, Xiaohuang and Guangling workshops, fermented tofu has gradually been promoted everywhere. Now, after "trial sales" in Yecheng, the market response is good.

So the fermented tofu workshop was officially put into production, and fermented tofu was made in large quantities, with good profit prospects.

As the behind-the-scenes driver, Yuwen Wen was very satisfied with the situation in the workshop, but the faint sadness in his heart still couldn't get rid of it.

He took another bite of green fermented bean curd, and he felt a little sad: Who wants green tofu, what I want is penicillin!

Penicillin, transliterated as penicillin, is an antibiotic and a life-saving magic medicine. With this thing, tuberculosis, which is regarded as a terminal illness in this era, is no longer terrible.

In addition, all the wounds are suppurated and bacterial infections caused by terminal illnesses are all over the world.

Yuwen Wen was afraid that he and his family would suffer from tuberculosis and end up in dying. He was also afraid that he and his sons would accidentally get injured on the battlefield, and the wound would become suppurated and eventually died of high fever. So he knew it was very difficult, but he still wanted to prepare penicillin.

I have watched the complete process of producing penicillin on TV, so it is not impossible!

Yuwen Wen thought that based on a certain TV series he had watched, he had seen how to use the native method to make penicillin.

So he began the great process of producing penicillin, and invested countless manpower, material resources and financial resources to this end. It took more than ten years to finally obtain fermented tofu made from penicillin.

Penicillin? It does not exist.

Although his technicians have indeed cultivated Penicillium that can kill mold by relying on the "exhaustion method", it is impossible to effectively extract penicillin, let alone identify toxicity, which is simply impossible.

The huge technical barrier cannot be solved by an amateur like Yuwen Wen who can "learn penicillin when watching TV". His ambitions are destined to be a dream.

Although the matter has passed and he has given up his ambition to make penicillin, the past is unbearable to look back. Thinking of this, Yuwen Wen still feels bleeding: I don’t know how good it is to spend money burned to make penicillin!

The development of the new drug "penicillin" failed. The drug merchant Yuwen Wen vomited blood even though he lost money, so he could only find a way to make up for the losses and at least make up for some money.

Because of the development of penicillin, Yu Wenwen has a primary "bacterial laboratory" and has cultivated a group of microbiology technicians. With the help of microscopy, these technicians have a preliminary understanding of the world of microbiology.

The technicians who have been working hard to extract penicillin have the basic qualities to continue to study microorganisms, so the laboratory "changed" and transformed the research results into profitable technologies, one of which is the fermented tofu industry.

The second is brewing. The ale (beer) that is now popular, "Bozhou Horse Urine". Its brewing wine and brewing technology are one of the achievements.

The third is mass production of yeast.

When thinking of yeast, Yuwen's mood was resentful. The yeast produced in the yeast workshop was used to produce noodles with amazing effects, which was very popular in areas where pasta is the staple food.

The yeast workshop has achieved small profits but quick turnover by selling yeast in large quantities, becoming another chicken that lays golden eggs among many industries in Yuwen Wen.

The unexpected yeast industry allows Yuwen Wen to slowly make up for the huge losses caused by the preparation of penicillin.

Yuwen Wen tried his best to get the "industry transfer" of Huangzhou's industries. He opened a semicolon in Yecheng with the purpose of making money. While making money, he wanted to attract a large number of landless people to the city and support himself and his family by relying on "working".

Daxing Industrial will win multiple good things in one fell swoop, benefiting the country and the people.
Chapter completed!
