Chapter 922 Medical Expert Little Fairy ([-])
Mr. Luther asked: "Does Staphylococcus aureus have anything to do with the penicillin we are going to study?"

"Of course there is." Bai Weiyang said convincingly, shrugging her shoulders incomparably at ease, picked up a bean on the plate and put it on the table, and pointed to the bean as a metaphor, ""Staphylococcus aureus", the cell wall contains 90% peptidoglycan and 10% teichoic acid. The peptidoglycan network structure is denser than that of Gram-negative bacteria. When staining, crystal violet is not decolorized by alcohol after staining, so it appears purple. On the contrary, the cell wall of negative bacteria The peptidoglycan layer is thin, poorly cross-linked, and high in lipids, so the purple complex is washed away by the alcohol and attaches a sandy red color."

This is relatively professional knowledge. She is proficient in French, but this is the scope of medical professional terms, and she uses English to explain.

Bai Weiyang smiled meaningfully: "But, have you ever tried to put Staphylococcus aureus on agarose plate culture medium for a long time?"

"No."

Everyone shook their heads.

Who would put Staphylococcus aureus on the agarose plate medium properly! !

Bai Weiyang smiled calmly, continued to play with the green bean, sprinkled a layer of white sugar on the bean, and said lightly: "I tried to put Staphylococcus aureus on the agarose plate medium for about 52 days. After culturing at room temperature, you will get a variety of mutated colonies, even white colonies. Those white colonies contain a mold on them, which is exactly Penicillin! Penicillin only has a significant effect on Gram-positive bacteria represented by Staphylococcus aureus. This It is also caused by the thickness and structure of the peptidoglycan layer."

Mr. Martin was shocked, "What? You have already researched it?"

Bai Weiyang said with a half-smile: "That's why I published a paper "On the Bactericidal Effect of Mold Culture"! It was derived from that research."

"The little fairy asked us to come here, what needs to be done." She has already researched it, and everyone started to look at her with new admiration.

"Because Penicillin is extremely difficult to extract and its activity is unstable. I can't solve these problems, so I need everyone to brainstorm. I believe that as the pioneers and benchmark leaders in the French medical field, we can't solve this problem if we get together. I'm afraid, no one on this planet can solve it. Right?"

Bai Weiyang praised all the medical experts present with a pleasant smile.

Scholars are very useful to hear this.They all patted their chests.

"Yes, as representatives of the French medical community, we are cutting-edge talents in modern medicine. If we can't solve this problem together, I'm afraid no one will be able to solve it."

Gu Changfeng: ...? ?

She is putting a high hat on you, do you understand?

He understood her discovery.

But what she wants to do is to purify and mass-produce it. I'm afraid she has an idea. Calling these people is just to research it openly and make penicillin mass-produced.

Seeing that everyone was aroused, Bai Weiyang hurriedly said: "I need a purification experiment, I have asked Gu Changfeng to prepare a laboratory, which can be used for everyone's research."

Several scholars glanced at each other, and Mr. Thomas immediately said: "Little fairy, since you believe in our ability so much, during this time, we have asked Mr. Schneider to prepare a perfect scientific research laboratory in the French Concession! Do research on penicillin. The equipment in the laboratory is the most advanced biological purification equipment, and it must be of great need to you."

Bai Weiyang knew what little calculations the French were planning.
