Let it go, let it go, don't sprinkle the milk, this thing is expensive. ”

With Ah Chang's shouting, several people carried a bucket of milk down from the house, and a piece of glass buckled on it was taken off, Ah Chang touched the wall of the bucket, and the temperature was already lower than the temperature on his hand.

"Little Liuzi, go and call Shizun, and say that the rice milk and milk are ready, and the temperature is just right."

Xiao Liuzi just ran to the door, and before Zhou Heng took someone downstairs, he walked quickly towards Ah Chang's position.

Zhou Heng took a look, the rice milk was very viscous, there was a layer of milk skin floating on the milk, it was very thick when it looked at it, there were a lot of two things, there were two large buckets, and when he saw a box of petri dishes behind, Zhou Heng waved his hand.

The conditions are limited, and Zhou Heng wants to make a more suitable medium for the growth of Penicillium, after all, there is no Cha's agar, no Cha's yeast paste agar, no wort agar, and no beer wort agar.

Therefore, only the original medium can be made, but the effect is still no different.

"Move all these things to the small room at the back of the first floor, I will teach you to make a culture medium, and in the future, I will make it according to this method, and now that the weather is cold, it can be stored for more than ten days without corruption."

Ah Chang hurriedly led someone to carry these things into the room, and of course he didn't leave the plates of penicillium plaques.

"Go and get me a few pieces of gauze three feet by three feet square, both roving and spun, and bring me a bucket of distilled water, and a few basins."

Qu Ziping was quick with his hands and feet, and he had already taken someone to get it, and he would get it back in a short time.

Zhou Heng poured a plate of penicillium into a basin, and then asked people to pour distilled water, and in an instant, the green mold in the entire basin floated up.

Hand a long spoon to Xiao Liuzi, "Don't be impatient, stir slowly, let these molds dissolve in the water and then filter, add water and stir again like this, and then filter again, do you understand?" ”

Xiao Liuzi nodded, took two people, made three basins, and began to stir slowly, the movements were extremely gentle, after all, they were all from the medicine group, and the hands and feet were quick and accurate, and the people around them watched their movements without blinking.

Zhou Heng looked at it and walked towards Ah Chang with a smile, a sterilized kettle was placed on the table, Zhou Heng measured the rice milk, taro juice and milk in a ratio of one to one with a large beaker, and poured them into the pot uniformly.

Then he held the kettle, stirred evenly, picked up a petri dish, poured the natural nutrient solution into it, it seemed that the temperature was getting lower and lower, the juice had become extremely viscous, and after pouring it for a while, it was like fat and half-solidified attached to the bottom of the petri dish.

Zhou Heng handed the kettle to Ah Chang, "Just pour one-third of the petri dish one by one, the principle is to spread one layer, and then don't shake the time of a tea, it will solidify, just make fifty, and then find a place with the lowest temperature to store." ”

Ah Chang took the kettle, and the movements in his hand did not stop, but his face still looked a little puzzled.

"Master, could it be that these rice soups can also be used as medicine?"

Zhou Heng shook his head, "It's useless to say it at the moment, you will know later, hurry up and get the next step." ”

Ah Chang didn't pause and hurriedly started making petri dishes, Zhou Heng approached Xiao Liuzi and a few of them, the mold had quickly dissolved into the water, and the color in the water became green, but there were still a lot of impurities in the large pieces.

"Alright, stop stirring."

Xiao Liuzi stopped moving, Zhou Heng glanced at the liquid and glanced at the gauze.

"Find the coarsest gauze, filter it for the first time, and filter out the pulp and large impurities."

Xiao Liuzi nodded, picked up the basin, and poured the liquid into the basin covered with a layer of gauze, which left large pieces of pulp, but very few penicillium plaques remained.

Soon, several large basins were preliminarily coarsely filtered, Zhou Heng took a look at the liquid, and the concentration of the turbid cyan blue liquid was still very high, and a smile appeared on his face.

Raising his eyes, he continued: "Find me some of these small water tanks, the kind that have been disinfected before." ”

Xiao Liuzi hurriedly brought someone to bring some stoneware jars for medicine, and Zhou Heng pointed to the basin and ordered:

"Pour these mixtures into the tank, remember to pour one-third, and then pour one-third of the nutrient solution made by Achang, cover the tank with a white cloth, tie it tightly with a rope outside, and send someone to the next door of the alcohol room, where the temperature is high and easy to ferment and suitable for mold growth, and the low temperature environment takes seven days, if it is next door to the alcohol room, it can be purified after four or five days."

There was no need to command, a few handymen stepped forward and walked towards the next door of the alcohol room with more than a dozen large vats, and Ah Chang did not forget to shout in the back:

"Go find Brother Xue, we bought a lock and locked the room in a while."

At this moment, the window on the second floor poked his head out, and Ma Lingshan called Zhou Heng with some excitement.

"Master, it seems that the microscope can be used this time."

Zhou Heng's face was overjoyed, and he hurriedly walked upstairs and returned to the room where he was doing research, and Liu Xiu'er hurriedly gave him a place.

Ma Lingshan has eagerly introduced, "Just now I and my little sister debugged again, and found that the lenses we installed were in the opposite direction, so we took them apart and reinstalled them. ”

Zhou Heng approached and looked down with a low magnification, there was already a piece of mold the size of a needle tip on the two glass slides, looking at it from the low magnification, Zhou Heng soon found the position, not to mention that the magnification was good, Zhou Heng adjusted to the position of the high magnification, this is a small point where the mold can be seen, Zhou Heng was a little excited.

Unexpectedly, according to their own memory, they drew such a flawed microscope diagram, and they actually made it, from the magnification point of view, this high magnification should reach more than 400 times, as for how much, it's really hard to say.

Zhou Heng found a small bottle, which was filled with grease.

Even if the microscope they made is a high magnification, the magnification is still limited, so they can only use an oil mirror to increase the magnification, but this is all the information that Zhou Heng checked when he was in school, and he didn't know if it could be realized.

Taking a deep breath, the oil fell low on the outer layer of the slide, Zhou Heng adjusted the position of the oil mirror, slowly moved down, and in an instant, there was still a small mold in the eyepiece, which was magnified, and one by one the dendritic hyphae appeared in front of him, Zhou Heng was a little excited, and let go of the position of the microscope.

"If it works, you can come and take a look."

Ma Lingshan hurried up, saw the mycelium, looked puzzled, and then looked at the slide, his eyes widened with an expression of disbelief.

"Master, this is this little dot on the glass piece, it can be magnified like a branch, how many times is this magnified?"

Zhou Heng picked up the pen and made a simple calculation on the book.

"If I'm right, that's a thousand, sixteen hundredfold expansion."

Mingyu, who was behind Boss Xue, poked his head over, and saw that Desheng and Liu Xiu'er had finished reading, so he hurried forward.

I put my eyes on the eyepiece, looked at the mycelium below, stared at it without blinking, and I didn't know what to think in my head.

Suddenly, Mingyu exclaimed, "Ah, how can this thing move?" I just saw a small bubble coming out of the corner of the branch, isn't it...... Is this growing? ”

Mingyu's words made Zhou Heng stunned, but he didn't expect Mingyu to be the first to find out that this thing was alive.

It seems that it is useful to read more, but literate people are different.

"That's right, this thing is called Penicillium, it's alive, if you're interested, you can find a patient who has been infected for many days, take some secretions from his wound, and then apply two boxes on the petri dish, one box is not disposed of, and the other box is smeared with a layer of penicillium like this on it, and after a few hours you can observe and see what changes have occurred in these molds."

This time, Ma Lingshan raised his hand and said: "I will look for the patient, there was an old man who came yesterday, his son's leg was broken, and he couldn't be treated by many medical centers before, saying that his calf was swollen and pus, and he was attracted to flies, so I asked him to come to the doctor early this morning, I don't know if he came." ”

As soon as the words fell, Qu Ziping hurriedly pushed the door in.

"Boss, there's a patient from outside Dr. Ma, and his leg is injured and someone has been carried here, so let's go down and take a look."

Zhou Heng was stunned and looked at Ma Lingshan, who quickly got up.

"It seems that this person is the son of the old man yesterday, master, I will go down and take a look first."

Zhou Heng stopped Ma Lingshan, "Wait, let's go together, Xiu'er will follow." ”

Liu Xiu'er was stunned, and her eyes instantly panicked.

"Ah, I'll go too?"
