Going out to do experiments is something that life science and medical laboratory researchers have been longing for for for a long time.

On the one hand, some data are not available in the laboratory and must be obtained in social scenes and nature. More importantly, everyone has been holding in the laboratory for too long. If they don't go out for ventilation, they have to jump into the colony pool and settle themselves.

Zhou Xiao made a plan for the outdoor experiment. The expected time of this outdoor experiment is two to three days. The main place is the districts and counties around Jiangcheng.

The contents involved are the sewage discharge outlet of the industrial zone, the gathering place of urban domestic sewage, the gathering place of rural garbage and sewage and the natural environment.

The purpose of the experiment is to study the treatment efficiency of digestive bacteria on non laboratory waste, and whether the experimental digestive bacteria can survive in nature.

The second experiment is very important. If digestive bacteria can survive and reproduce in nature under non laboratory conditions (i.e. non constant temperature, non culture medium environment), then the promotion and application of digestive bacteria will be a big question mark.

Nature is the most uncontrollable. If an emerging colony is uncontrollable, the disadvantages to human society will be far greater than overflow.

Zhou Xiao even chose to close the experiment.

Mo Li and others don't care so much. They completely take the going out experiment as an opportunity to relax. The little girl is even packing her bags and snacks

Zhou Xiao looked at the hot crowd and didn't want to spoil the fun, but kindly reminded: "remember to pack the experimental equipment."

"Oh, I know, I know! You're sitting in the car! " Mo Li pushes Zhou Xiao onto the business car.

The laboratory doesn't have its own business car. It's still borrowed from CHEN Ye.

At five o'clock in the evening, the crowd set out in a mighty manner.

The first stop of the destination is snack street in university town.

Zhou Xiao is the driver and commander this time.

After rubbing a meal in the snack street, the experiment began.

Mo Li and Zhang Sheng aim at the garbage and sewage everywhere in the snack street. In the words of eating goods Mo Li, the snack street is a collection of human domestic garbage.

The Spring Festival is more than a month away. Some students in the university town have no holidays, so the business of snack street is still very good.

People squatted at different stalls.

Zhou Xiao pointed to a barbecue stand and said, "see, there are a lot of garbage in this house, including glass and plastic bottles, milk bottles in cartons, bamboo sticks, shredded meat and toilet paper on the ground... Some of the shredded meat are not spicy, some of which are wrapped with snot."

Mo Li felt cold. "Boss, can you stop talking about the details so clearly? It's disgusting, isn't it good?"

Zhou Xiao said, "the details are the types of samples we take. Do you see the pollution discharge point outside the barbecue stand? I can't see very clearly, but there is sewage coming out... "

They didn't eat the barbecue, but it was disgusting.

Zhou Xiao said, "Zhang Sheng, take some garbage from each sample. The more kinds, the better. You should have bottles, toilet paper and broken meat. Mo Li, you go and sample the sewage. "

Everyone's good mood is gone. They also want to have a good supper in the snack street. Now they are good. They are in no mood.

Zhou Xiao said, "I'll do the experiment later. I'll treat you to a late night snack."

Who's in the mood for a late night snack.

Mo Li took the glass bottle and straw to the sewage ditch carefully. Wearing gloves and mask, she put the turbid and greasy sewage into the glass bottle.

Even wearing a mask, the smell of sewage comes to my nose.

This taste is stronger than the taste of digestive colonies. Mo Li has a nausea and has a shadow on the barbecue since then.

Zhang Sheng... It doesn't seem to be going well.

Barbecue shop owner: "what do you want to eat?"

Zhang Sheng's eyes kept staring around under the diner's table. He saw the target.

Zhang Sheng: "I'll just have a look."

The boss's business is very good and he doesn't bother to pay attention to Zhang Sheng.

Zhang Sheng collects garbage on the ground with plastic bags.

Diners can't bite rotten beef, leftover ribs, toilet paper with snot

Zhang Sheng almost vomited out his dinner while picking it up.

"This man is crazy!" Diners saw Zhang Sheng picking up disgusting garbage on the ground and make complaints about Tucao.

Zhang Sheng is just like them. These people always know what scientific and technological workers have paid for the development of human scientific and technological circles.

But when Zhang Sheng found a plastic bottle, the voice of the old aunt interrupted Zhang Sheng's dream of a scientist.

"This bottle is mine."

Zhang Sheng pointed to the drink bottle in his hand and the old aunt nodded.

"There's plenty around here. Pick it up! I just want one. "

The old aunt had held the bottle and said in a very serious tone, "I wrapped this piece. Your bottle is mine. I said, "young man, you have good feet and good hands. You can't do anything seriously. You can't compete with my old man."

The plastic bottle in Zhang Sheng's hand is very valuable. It is covered with dirt. There are still unfinished drinks in the bottle.

This is naturally formed garbage, which has research value. There are some new plastic bottle supermarkets, but they do not have research value.

Zhang Sheng also understands the old aunt's work very much. But if life is better, who picks up bottles here in the middle of the night.

Zhang Sheng said, "sister, can I buy a bottle of water to compensate you later? I really want this."

How can aunt believe Zhang Sheng's words“ I want this. What do you want from me, a young man? "

Now the diners are watching.

Zhang Sheng didn't want to entangle with her. He made a quick decision and said, "elder sister, do you think it's ok? Do you have a QR code? I scan the code to pay for it. No, this bottle when I buy it. "

What time is it? Zhang Sheng has no cash.

"What size or not, this bottle is mine!"

Looking at Zhang Sheng's helpless face, Mo Li quickly didn't come to the rescue and gave her a hundred yuan in cash to find it.

Old aunt: "I can't afford it."

Mo Li forbeared, "take the money and we'll take the bottle."

This operation is beyond everyone's comprehension.

A messy plastic bottle was collected with 100 yuan in cash!

No one at the scene took a short video joke on that mobile phone. It's true!

If you don't understand, you just don't understand.

Later, when diners saw this, they couldn't help joking: "sister, I still have some bottles here. Do you accept them? You count fifty-one?"

Mo Li couldn't help shouting, "stop!"

The process is tortuous, but the result is perfect. The garbage is collected in the car and will be studied after numbering and recording.

The garbage is numbered and recorded in detail, and even edited what dirt there is.

The experiment is extremely rigorous. In addition to determining that these sewage and garbage are treated by digestive bacteria, the experimenters also need to isolate what the products of digestive bacteria are after treatment.

After marking, Mo Li and others injected different groups of garbage and sewage into different stainless steel thermostatic containers with digestive bacteria.

After all this, it's already twelve o'clock in the evening.

Zhou Xiao said coldly, "I invite you to have a barbecue. It's hard today."

Mo Li, Zhang Sheng and others covered their stomach and retched.
