Chapter 366 Eight Steps of the Heavenly Dragon

"Yes, it's penicillin, penicillin."

Looking at Lin Xiao, who was startled, Yu Jifan smiled faintly and teased.

"Advance ...... Three hundred years? ”

Lin Xiao stretched out three fingers and gestured, and said suspiciously, "Can you really get it?" ”

"Don't believe me? Come with me, I'll show you the real hammer,"

Yu Jifan pouted, "What's so strange, you don't know, some technologies in later generations require strong industrial capabilities, which is indeed impossible in this era, but some technologies only need to pierce a layer of window paper......"

"Yes, yes, yes,"

Without waiting for Yu Jifan to finish speaking, Lin Xiao rubbed his hands happily, said three pairs in a row, and then waved his hand and shouted, "Let's go, take a look." ”

What Yu Jifan said naturally makes sense, and Lin Xiao also understands it.

For example, black powder, Zhou Gong from later generations, simply improved it according to the best formula commonly used in later generations, and increased the explosive power by more than fifty percent, which has nothing to do with industrial hard power at all.

For another example, people in this era don't know what raw rubber is for, and some children in South America often kick a ball of raw rubber as a ball.

But Lin Xiao and the others know that with a simple treatment, these rubbers can be made into various sealing rings, and can even be made into rubber shoes urgently needed by soldiers, rubber tires for large vehicles, etc., which basically does not require any difficult technology, it is purely a matter of vision and knowledge......

Of course, industrial flowers such as steam engines and internal combustion engines have to fight hard power, and they must not be opportunistic.

……

It was not for nothing that Lin Xiao was so excited about penicillin.

In his eyes, this is an unprecedented big business opportunity, and it was Yu Jifan who brought him a big pie.

You know, even if you put aside the fact that it came out hundreds of years earlier, penicillin was once much more precious than gold in the original history......

The discovery of penicillin, the first antibiotic, is indeed one of the most significant discoveries in the history of human medicine.

Because, for a long time, mankind has not been able to master a drug that can effectively treat bacterial infections and has few side effects.

At that time, even diseases such as tuberculosis were incurable, and if someone unfortunately contracted tuberculosis, it meant that the person would die soon.

Even more lamentingly, in World War I, a large number of wounded were amputated or lost their lives due to simple wound infections.

In order to change this situation, a large number of Western medical scientists and biologists have carried out long-term exploration.

However, God often likes to play a joke on humans, and the breakthrough in this area was made by an accidental discovery.

In 1928, British bacteriologist Alexander Fleming was lucky enough to discover penicillin due to an unintentional mistake.

One day, Fleming was working in a humble laboratory on a germ called staphylococcus.

However, because the lid of the petri dish was not properly covered, a penicillium spor floated in through the window and happened to land on the agar used to grow the bacteria.

As a result, Fleming was surprised to find that the staphylococci around the Penicillium spores had magically disappeared.

Fleming immediately concluded that Penicillium produced something harmful to staphylococcus, so he decided to do further research, which led to the invention of the miraculous antimicrobial drug "penicillin".

Unfortunately, however, it was not difficult to culture penicillin, but it was very difficult to isolate and purify, so Fleming was unable to find a way to extract high-purity penicillin.

After more than ten years of hard work, human beings finally mastered the method of purifying penicillin, which greatly enhanced the ability of human beings to resist bacterial infections and led to the birth of the antibiotic family.

Since then, antibiotics such as streptomycin, chloramphenicol, oxytetracycline, and tetracycline have been produced, which has greatly enhanced the ability of humans to treat infectious diseases.

It is no exaggeration to say that it was the discovery of penicillin that ushered in a new era of antibiotic treatment for diseases.

Later, through decades of refinement, penicillin injections and oral penicillin have been able to treat pneumonia, tuberculosis, meningitis, endocarditis, diphtheria, anthrax and many other conditions, respectively.

However, due to the low production of natural penicillin, this drug, called penicillin, was once very, very expensive, and for a long time, only high-ranking officials and nobles could use and afford it.

Of course, in the 21st century, when Lin Xiao and the others crossed over, semi-synthetic penicillin replaced natural penicillin, which had long since become a broad-spectrum antibiotic, saving countless lives, and the production cost was extremely low.

……

When he came to Yu Jifan's room, Lin Xiao found that this small laboratory was simply a utility room, full of large and small pots and jars of different shapes.

Yu Jifan didn't say anything big, he not only showed Lin Xiao the finished product in a small cake, but also explained the general steps of culturing and isolating penicillin with great interest.

"The process of making penicillin is actually very simple, only eight steps."

Yu Jifan led Lin Xiao to a large table and said, "Look at it, Tianlong Eight Steps, officially start ......"

"Poof......

Lin Xiao almost squirted, Tianlong Babu? What is the relationship with the eight steps of hair?

"First of all, it's a steamed bun, it's already moldy,"

Yu Jifan didn't care what Lin Xiao's reaction was, he picked up a moldy and green one from a small basket full of steamed buns, and pointed to a bowl next to him and said, "This is a soup made of rice juice mixed with sweet potatoes, and it is the culture liquid of bacteria......

"The second step is to scrape off the Penicillium and transplant it,"

Yu Jifan explained while operating, so that Lin Xiao could understand, "After this step, I will wait for cultivation, and it will take about a week ......."

"The third step is to filter the culture medium,"

Yu Jifan picked up a small crockpot on the table, sealed the top of the crockpot with a piece of oiled paper, cut a small hole in the oiled paper, then picked up a funnel, put a ball of medical cotton in the funnel, picked up another small bowl with pre-cultured culture, slowly poured it into the funnel, and kept explaining in his mouth, "This is a full seven days...... Then pour in the rapeseed oil and stir ......"

"Next, scoop the grease off,"

Yu Jifan picked up a small spoon and slowly scooped out the liquid in the crockpot, "Don't want the oil on it, just the water." ”

"Wait a minute, what is this?"

Lin Xiao didn't understand this step, in the spirit of humility and studiousness, he urgently stopped and asked an idiot question, "Since you don't want oil, then just now...... What are you pouring it in? ”

"This is to remove both insoluble and fat-soluble substances from the culture medium."

"Oh oh, got it, keep ......"

Lin Xiao's face was slightly red, and he waved his hand.

"Look, the fifth step, add the charcoal powder and stir well until it becomes a paste...... Isn't it simple? ”

Yu Jifan teased with a smile while stirring.

"Mmmm, it's okay, I can read it."

Lin Xiao was thick-skinned and laughed at himself.

"Step 6 is the most important and the most costly,"

Yu Jifan said, poured the black paste into a brand new white cotton cloth, and covered the cotton cloth on a large bowl, then picked up one from the glass bottle arranged on the table next to him, poured a little water from it, and slowly rinsed the paste in the cotton cloth, "The cotton cloth should be boiled...... This is distilled water......"

Pick up another one and rinse it, "This is water with vinegar ......"

Pick up another one and rinse, "This is seaweed juice ......"

"Wait,"

Lin Xiao frowned and stopped again, "How do you get distilled water?" ”

"How else can I get it? The soil method is on the horse, and the lid of the pot is dripping,"

Yu Jifan smiled bitterly, "I asked Lao Cao to make a few large iron pots, which are specially used to boil water, and the lid is tilted, of course, it is also iron...... Isn't it easy to get a lot of distilled water? ”

"Uh-huh,"

At this point, Lin Xiao didn't blush at all, but sneered, "What kind of high cost is this?" ”

(Question: Since the beginning of modern times, a large number of people who have risen to the top of the earth in Hunan have risen to save the country, so there is a saying that "Hunan is half a talented country", can you name two of them?) ）
