Cellulose and hemicellulose account for a large proportion of dead plants, and cellulose is a polymer of glucose, which has the ability to resist various oxidants due to its special structure. The microorganisms and the action on cellulose depend entirely on the function of the microorganisms and the conditions under which they are decomposed.

Generally speaking, under normal conditions, it takes 2-3 years for various scavenging microorganisms to completely decompose dead plants.

What Chen Cheng needs to do is to develop a super degradable microorganism, preferably to shorten the degradation time to less than 1 year.

He decided to use urease microorganisms like those at that time, or through iterative culture, to enhance the degradation ability of microorganisms.

Common microorganisms that degrade plants are white rot fungi, Aspergillus niger, Trichoderma viridum. Chen Cheng called up their information one by one.

White rot fungi are a kind of fungi that make dead plants appear white decay, which can secrete extracellular oxidase to degrade lignin, and the ability to degrade lignin is better than the ability to degrade cellulose, these enzymes can promote wood decay into a colorful spongy mass - white rot, so it is called white rot fungi.

Aspergillus niger is black-brown in color, with a large spherical parietal sac, a bilayer of small peduncles, and a spherical conidia, black, black-brown, smooth or coarse. It is resistant to ultraviolet rays and ozone. The hyphae are well developed, multi-branched, multicellular fungi with multiple nucleations.

The conidia are made up of specialized thick walls that grow vertically from the enlarged hyphal cells (podocytes), and the conidia are head-like like "chrysanthemums".

Trichoderma viridis is a type of Trichoderma fungus, which is widely distributed in nature and often saprophytes on wood, seeds and plant residues.

Trichoderma viridis can produce a variety of biologically active enzyme systems, and the strain with the highest cellulase activity is produced, and the cellulase produced has a very good effect on crops.

Chen Cheng used a supercomputer to simulate the offspring of the three microorganisms with enhanced decomposition ability, and then mixed them into the soil.

"Start simulating the decomposition of plants." Chen Cheng said.

【Okay】

In less than a minute, the system suddenly sounded.

[Simulation error, terminate experiment]

"What's the situation?" Chen Cheng hurriedly went to look at the simulation process.

It turns out that these three improved degrading microorganisms are indeed effective, but at the same time, they also corrode some of the watermelon rhizomes in the growing period, causing the watermelon root system to rot and eventually causing the plant to die.

"This..."

Chen Cheng really didn't expect such an effect.

Everything in nature has its original logic, and if there is a sudden change in a certain force, it will cause an imbalance.

If you lose your balance, you can go wrong.

Just as he was racking his brains, Wang Kai called him outside.

Chen Cheng simply cleaned up and walked out.

Wang Kai, who was standing outside the laboratory, rubbed his hands and said, "Lao Chen, do you know what day it is?" You're still busy. ”

"The Point Guard Is Here"

"What day?" Chen Cheng asked.

"Chinese New Year's Eve!" Wang Kaidao.

Only then did Chen Cheng react.

"Why did it go so fast?" He muttered.

"It's because you're living the same every day, so you don't know how many days have passed." Wang Kai said.

"Brother Kai, what are you looking for me?" Chen Cheng asked.

Wang Kai said: "A few of us discussed, let's cook a hot pot in the bedroom tonight, and Ding Tao and they all went out to buy something." I'll call you back to your bedroom. ”

"Let's cook hot pot in the dormitory, won't the dormitory aunt pull the gate?"

"No, I asked, the dormitory manager aunt is going home for the New Year tonight. In the entire dormitory building, only 404 of us has someone to stay overnight. ”

"That's good. Let's go. Chen Cheng packed up the laboratory and walked back with Wang Kai.

...

When night fell, the colorful light strips were lit up in the 404 dormitory of Building 3 of the West Garden of Agricultural University, and the 'Spring Festival Gala' of the five men officially began.

A small hot pot boiled on an induction cooker, filled with all kinds of meat and vegetables, five bottles of beer on a small table, and two boxes behind Wang Kai.

"Come on, let's have a drink!" Chen Cheng proposed.

The other four held up beer bottles.

"Don't you have to say a couple of words before drinking?" Wang Kai asked.

Lao Xu and the others also looked at Chen Cheng.

Chen Cheng coughed, and then said, "Since this is the case, then I will say two words." First of all, I would like to thank you for your help in the past year. The second sentence is that I hope we can make persistent efforts in the coming year and create more brilliant results. ”

"Good!"

The five touched the bottle, and each drank it all.

After finishing a bottle of beer, a few people sat down and started eating.

Lao Xu opened two bottles of beer and handed one to Chen Cheng.

"Lao Chen, thank you." Lao Xu touched the bottle with him with emotion.

"Huh... Lao Chen, let's drink half of it. Drink another bottle, and I won't be able to eat this hot pot. Chen Cheng said.

"Good!"

After the two of them finished drinking, Lao Xu said: "Lao Chen, I am going to apply for the insurance research next year, and my supervisor told me to recommend the graduate students of the Institute of Agricultural Sciences." ”

"What a good thing!" ×3.

"So, I said thank you." Lao Xu said to Chen Cheng: "If it weren't for your project as a black pig in Iasi, I might not be able to pass my application for insurance research." ”

Chen Cheng said: "Lao Xu, don't be presumptuous, I recently conducted research with you, and I found that your level of ability is very high."

It's just that you went to the Institute of Agricultural Sciences, can you continue to study this project in the future? ”

Lao Xu shook his head: "It depends on whether there are relevant projects on the side of the Institute of Agricultural Sciences." ”

Wang Kai sighed: "Hey, it's all because our Agricultural University doesn't have a master's degree. ”

As soon as Lao Xu came up, he mentioned this kind of sad thing, which made several people feel a little uncomfortable.

But this is an inevitable thing, after all, they have all reached the time of graduation and separation.

After the New Year, there are only a few months of college time left.

Chen Cheng thought for a while and said, "I'll visit President Zhao in two days to see if our school can introduce a few more professors and apply for a master's degree in two years." ”

"If you want me to say, Lao Chen, you should use your influence to apply for an academician as soon as possible."

"To apply for an academician, you must have the title of researcher." Ding Tao reminded.

Chen Cheng also found out that he had been busy with experiments and technology for more than half a year, and he had forgotten his job title.

"By the time I get to the researcher, it's probably been years." Chen Cheng said.

Wang Kai was unconvinced: "Your technical level is enough to apply for academicians." ”

Chen Cheng raised the wine bottle, and several people touched the bottle again, and then drank.

After half a bottle of wine, Chen Cheng asked Lao Xu: "Do you want to stay in school?" ”

Lao Xu asked: "I'm about to graduate, how can I stay?" ”

"I'm going to put you in charge of the Iasi Black Pig Research Project. By following the program, you have an income and at the same time you have the title of teaching assistant in the school. When the technical results of this project come out in the future, you can evaluate the job title, and you will be a teacher or full-time research in the future. ”

Lao Xu thought for a while, took a sip of wine, and then nodded vigorously.
