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

On the one hand, it is because some data are not available in the laboratory and must be obtained in social scenes and nature, and more importantly, everyone has been in the laboratory for too long, and if they don't go out to breathe, they will jump out of the colony pool and end up by themselves.

Zhou Xiao made a plan to go out for the experiment, and the estimated time for this outing experiment is two to three days, and the main location is the surrounding districts and counties of Jiangcheng.

The contents involved are sewage outlets in industrial areas, domestic sewage gathering places in cities, rural garbage and sewage gathering places, and the natural environment.

The purpose of the experiment was to study the efficiency of digestive colonies in the treatment of non-laboratory waste, and whether the experimental digestive bacteria could survive in nature under non-laboratory conditions.

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

Nature is the most uncontrollable, and if an emerging colony is uncontrollable, the harm to human society far outweighs the spillover.

Zhou Xiao will even choose to close the experiment and end this experiment.

Mo Li and the others didn't care so much, they completely regarded the experiment as an opportunity to relax, and the little girl was even packing her luggage and snacks......

Zhou Xiao looked at the enthusiastic crowd and didn't want to ruin the fun, but kindly reminded: "Remember to pack the experimental equipment." ”

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

The laboratory does not have its own business car, and this car is still borrowed from Chen Ye.

At five o'clock in the evening, everyone set off in a mighty manner.

The first stop of the destination, the snack street of the university town.

Zhou Xiao is the driver and commander this time.

After a meal at the snack street, the experiment began.

Mo Li and Zhang Sheng are targeting the garbage and sewage that are all over the ground in the snack street, which, in the words of foodie Mo Li, is a collection of human domestic waste.

There is still more than a month before the Spring Festival, and there are still some students in the university town who do not have a holiday, so the business of the snack street is still very good.

Everyone squatted and stood guard at different stalls.

Zhou Xiao pointed to a barbecue stall and said: "See, there is a lot of garbage in this house, glass and plastic bottles, as well as milk bottles in cartons, and bamboo skewers, minced meat, and toilet paper on the ground...... The minced meat is not spicy or spicy, and there are chili peppers on the toilet paper, and some are covered with snot. ”

Mo Li felt a chill, "Boss, can you not tell the details so clearly, this is disgusting, okay." ”

Zhou Xiao said: "The details are the types of samples we sampled, do you see such sewage points outside the barbecue stall?" I can't see it very clearly, but there's sewage coming out......"

The crowd didn't eat the barbecue, but it was nauseous.

Zhou Xiao instructed: "Zhang Sheng, you go and sample garbage, take a little bit of each sample, the more types the better, bottles, toilet paper, and minced meat." Mo Li, you go and sample the sewage. ”

Everyone's good mood disappeared all of a sudden, and they still wanted to have a good supper in the snack street, but now it's okay, and there is no mood at all.

Zhou Xiao said: "I will do the experiment first in a while, and I will invite everyone to have supper." ”

Who has the heart to eat supper.

Mo Li cautiously came to the sewage ditch with a glass bottle and a straw, and she wore gloves and a mask to put the muddy and greasy sewage into the glass bottle.

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

The taste was stronger than the taste of digesting the colonies, and Mo Li was sick to his stomach for a while, and since then he has a shadow on the barbecue.

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

Barbecue restaurant owner: "What do you want to eat handsome guy?" ”

Zhang Sheng's eyes kept staring under the diner's table, and he saw the target.

Zhang Sheng: "I'll just take a look." ”

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

Zhang Sheng uses plastic bags to collect garbage on the ground.

Beef that diners can't chew on, leftover ribs, toilet paper with snot......

Zhang Sheng gagged while picking it up, and almost vomited out of dinner.

"This man is insane!" When the diners saw Zhang Sheng picking up disgusting garbage on the ground, they couldn't help but complain.

Zhang Sheng is just like them, these people will always know everything that scientific and technological workers have done for the development of the human scientific and technological community.

But when Zhang Sheng picked up a plastic bottle, the old aunt's voice interrupted Zhang Sheng's dream as a scientist.

"This bottle is mine."

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

"There's so much around here, you can pick it up casually! I only need one. ”

The old aunt had already pinched the bottle and said in a very serious tone: "I have covered this piece, and your bottle is mine." I said, young man, you are so good at doing something serious, what kind of business is you stealing from my old fellow. ”

The plastic bottle in Zhang Sheng's hand was very valuable, it was covered with filth, and there were unfinished drinks in the bottle.

This is naturally occurring garbage, which has both research value, and the new plastic bottle supermarket has it, but it does not have research value.

Zhang Sheng also understands the work of the old aunt very well, but whoever has a better life, who picks up bottles here in the middle of the night.

Zhang Sheng said: "Eldest sister, I'll buy a bottle of water to compensate you later, I really want this." ”

Zhang Sheng's words, how can my aunt believe it. "I just want this, what are you young man robbing with me."

Now the diners are watching the excitement.

Zhang Sheng didn't want to entangle with her, so he quickly said, "Eldest sister, do you think this is okay?" Do you have a QR code? I scanned the code to pay the money no, this bottle when I bought it. ”

What era is it, Zhang Sheng has no cash.

"What's not a yard, this bottle is mine!"

Seeing Zhang Sheng's helpless look, Mo Li hurriedly didn't come to solve the siege, and gave the eldest sister a hundred yuan in cash for the eldest sister to find.

Old Aunt: "I can't afford to find it." ”

Mo Li endured it, "You take the money, we want the bottle." ”

This saucy operation makes everyone incomprehensible.

A messy plastic bottle was actually collected for 100 yuan in cash!

There was no one at the scene who took a short video spoof with his mobile phone, it was a real thing!

If you can't understand it, you just can't understand it.

Later, when the diners saw this, they couldn't help but joke: "Sister, I still have some bottles here, do you accept them, do you count fifty-one?" ”

Mo Li couldn't help but shout: "Shut it up!" ”

The process was tortuous but the result was perfect, the garbage was collected in the car, and the number was recorded and then the research was done.

The garbage is numbered and recorded in detail, and even edited to see what the filth is.

The experiment is extremely rigorous, and the experimenter has to determine not only that the sewage and garbage have been treated by the digestive bacteria, but also to isolate what the products of the digestive bacteria are treated.

After the labeling, Mo Li and others injected different groups of garbage and sewage into different stainless steel thermostatic containers, which contained digestive bacteria.

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

Zhou Xiao said coldly: "I invite everyone to eat barbecue, everyone has worked hard today." ”

Mo Li, Zhang Sheng and the others clutched their stomachs and retched.
