Xu Yang had planned to take out the plastic bag when he analyzed and took samples the next day, but found that there was nothing in the glassware.

Digestive colonies are pale green when they are first cultured, and over time, the amount of decomposed organic matter increases to a dark yellow-green color.

Since he couldn't see what was inside, and the volume of the glass container was not large, Xu Yang found a stainless steel leaky scoop in the kitchen to salvage it in the container.

Xu Yang didn't dare to use his hands, the components of his skin are also proteins and fats, which will be broken down by bacteria.

After fishing for a long time, there was nothing but bone slag that had not been decomposed by the colony.

Xu Yang thinks that he is not mistaken, in the study of digestive colonies, digestive colonies can indeed decompose organic matter, but plastic bags are polymers, which will not be degraded for hundreds of years in nature, and the digestive colonies will decompose in just one night?

"Xu Yang, what are you doing! Guarding the water tank, what is the stunned, the data is out, and the boss wants to see the data for a while. Mo Li came over with a bunch of materials and said.

The water tank is an interesting name for the culture vessel in the laboratory.

Xu Yang grabbed his hair and said, "Right away." ”

The recent experimental data was summarized in Zhou Xiao's hands, and Zhou Xiao organized a meeting.

The environment of the new science and technology area is very beautiful, and the scenery by the lake where the laboratory is located is even more beautiful.

In early winter, due to the proximity of the new science and technology area to the mountains (Lingwu Mountain), the temperature was already several degrees lower than the outside, and in the past few days, it has been possible to see that the distant peaks in the distance have been topped with a layer of snow, and the hay next to the lake has frost in the morning.

But with such a beautiful scenery, Zhou Xiao and the experimenters didn't have time to see it, and they didn't even go out of the door of the laboratory.

Since the laboratory is strictly confidential, outsiders are not allowed to enter. Therefore, every day, the staff brings fresh vegetables, fruits, meat, etc., and the researchers are divided into groups to cook, wash dishes, and clean up.

Everyone has been in the laboratory for more than a month and has not been out, and it seems that it is about to be New Year's Day, and then the Spring Festival is coming.

Life Science and Medical Research Center (Laboratory), Zhou Xiao held a meeting.

After reading the data, Zhou Xiao said: "Let's emancipate our minds, don't think about whether our experiments are useful, we have to think about how to use the most efficient way to cultivate digestive bacteria." ”

Zhou Xiao said: "If everyone is wondering whether it is useful for us to study this thing, our experiment should not continue." ”

"The difficulty of the experiment now is the reproduction of colonies, at present, the colonies in our colony culture vessels will die after the end of the life cycle, and they cannot reproduce independently in the culture vessels, which is very troublesome, the information I showed you that day has pointed out the direction for our experiments, and you can completely emancipate your mind and try more......"

Zhou Xiao said: "If you have to talk about the application of our research object, then I will briefly say a few words. At a temperature of 36.5 to 37 degrees, if digestive bacteria can survive in the body in a certain way without eroding our body, will it be able to help us digest food? I'm just thinking outside the box, and being is reasonable. ”

Zhou Xiao is throwing bricks and stones, but it does shock the people in the laboratory.

Some time ago, experiments have proved that the products of organic decomposition by digestive bacteria can be absorbed by the human body, which is of important clinical significance.

Mo Li whispered to Zhang Sheng: "I used to stay in the Department of Gastroenterology when I was an intern, and many patients with advanced gastrointestinal cancer have been controlled, but their digestive organs such as the stomach and intestines are all ulcerated and can no longer work. At this time, even if the patient relies on the infusion of nutrient solution to hang his life, although he will not die for the time being, his life is also very inconvenient, and he basically waits for death in bed. ”

"If you can build a new digestive system in the body, it will definitely be a big breakthrough in the medical world!"

Zhang Sheng also said: "Does the commensal protein produce a little glucose? ”

"Go!" Mo Li said, "I'm having a pure medical discussion with you. ”

Zhang Sheng gave Zhou Xiao a thumbs up, the boss is the boss, and the issues he considers are indeed much more thoughtful than everyone else.

But how to survive in the body without eroding the body is a difficult problem.

Zhou Xiao is actually not very worried about the independent reproduction of digestive bacteria, with the science and technology compendium and the technology accumulated by Origin Technology for such a long time, it is only a matter of time to complete the reproduction experiment of digestive bacteria.

When Zhou Xiao was speaking, Xu Yang was a little distracted, he kept thinking about where the plastic bags went?

This plastic bag is a bag for delivering vegetables outside, and it is a high-density polyethylene material, which is very difficult to degrade.

In terms of treatment process, it is generally recycled and reprocessed, and the recovery rate is about 25%.

That is, only 25% of the used plastic bags are recycled, and the rest are turned into ethane, water, hydrogen, and so on in the recycling process.

If you want to use the report to write the equation and reaction principle of the recovery reaction, I am afraid that there are no three or five thousand words that cannot be explained.

This shows that high-density polyethylene plastic bags are very difficult to degrade.

In addition, the places where plastic bags are used most in Xia are in third- and fourth-tier cities or towns, and the recycling rate is even worse.

Most of the high-density polyethylene plastic bags will be recycled and landfilled and incinerated.

Xu Yang really can't figure it out!

After Zhou Xiao finished assigning the task, everyone took their places and continued to start technical research.

Tonight, Xu Yang was in charge of washing the dishes, and all the leftovers were put in the bag.

If it is a regular operation, Xu Yang will pack the garbage bag and put it in the kitchen and give it to the aunt who delivers the food tomorrow.

This time, Xu Yang was both lazy and wanted to confirm what he thought in his heart, and came to the constant temperature laboratory again.

Xu Yang began to prepare.

He set up the camera in a suitable position and turned on the time-lapse (the laboratory is completely secret, and no one is allowed to bring a cell phone or other means of communication).

Xu Yang then put all the food scraps into the container, and then tied the end of the garbage bag with a rope and hung it in the air, half of which was submerged in the colony solution and half of which was exposed.

Zhang Sheng said after verifying a data in the constant temperature laboratory: "Brother Yang, it's eleven o'clock, you still don't want to go back?" Let's go back and play a game, I haven't played for two days, and my hands are itchy. ”

In the boring days of experimentation, playing chess, playing cards, and watching TV are not many ways for everyone to relax.

"No, I have another experiment project at night, and I won't be back in my room tonight." Xu Yang is going to spend one night in the glass room of the constant temperature laboratory (with air conditioning, and the temperature is isolated from the constant temperature laboratory) to record the data of the experiment for the first time and confirm his ideas.
